title: "Boeing 707" content: Boeing 707 The Boeing 707 is a mid-sized, long-range, narrow-body, four-engine jet airliner built by Boeing Commercial Airplanes from 1958 to 1979. Its name is commonly pronounced as "seven oh seven". Versions of the aircraft have a capacity from 140 to 219 passengers and a range of . Developed as Boeing's first jet airliner, the 707 is a swept-wing design with podded engines. Although it was not the first jetliner in service, the 707 was the first to be commercially successful. Dominating passenger air transport in the 1960s and remaining common through the 1970s, the 707 is generally credited with

title: "Boeing 707" content: ushering in the Jet Age. It established Boeing as one of the largest manufacturers of passenger aircraft, and led to the later series of airliners with "7x7" designations. The later 720, 727, 737, and 757 share elements of the 707's fuselage design. The 707 was developed from the Boeing 367-80, a prototype jet first flown in 1954. A larger fuselage cross-section and other modifications resulted in the initial-production 707-120, powered by Pratt & Whitney JT3C turbojet engines, which first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958. Later derivatives included the

title: "Boeing 707" content: shortened long-range 707-138 and the stretched 707-320, both of which entered service in 1959. A smaller short-range variant, the 720, was introduced in 1960. The 707-420, a version of the stretched 707 with Rolls-Royce Conway turbofans, debuted in 1960, while Pratt & Whitney JT3D turbofans debuted on the 707-120B and 707-320B models in 1961 and 1962, respectively. The 707 has been used on domestic, transcontinental, and transatlantic flights, and for cargo and military applications. A convertible passenger-freighter model, the 707-320C, entered service in 1963, and passenger 707s have been modified to freighter configurations. Military derivatives include the E-3 Sentry airborne

title: "Boeing 707" content: reconnaissance aircraft and the C-137 Stratoliner VIP transports. Boeing produced and delivered 1,011 airliners including the smaller 720 series; over 800 military versions were also produced. As of July 2017, there were no active 707s in commercial airline service. During and after World War II, Boeing was known for its military aircraft. The company had produced innovative and important bombers, from the B-17 Flying Fortress and B-29 Superfortress, to the jet-powered B-47 Stratojet and B-52 Stratofortress. The company's civil aviation department lagged far behind Douglas and other competitors, the only noteworthy airliners being the Boeing 314 Clipper and 307 Stratoliner.

title: "Boeing 707" content: During 1949–1950, Boeing embarked on studies for a new jet transport, realizing that any design must be aimed at both the military and civilian markets. At the time, aerial refueling was becoming a standard technique for military aircraft, with over 800 KC-97 Stratofreighters on order. With the advent of the Jet Age, a new tanker was required to meet the USAF's fleet of jet-powered bombers; this was where Boeing's new design would potentially win military orders. Boeing studied numerous wing and engine layouts for its new transport/tanker, some of which were based on the B-47 and C-97, before settling on

title: "Boeing 707" content: 367−80. The "Dash 80" took less than two years from project launch in 1952 to rollout on May 14, 1954, then first flew on July 15, 1954. It was powered by the Pratt & Whitney JT3C turbojet engine, which was the civilian version of the J57 used on many military aircraft of the day, including the F-100 Super Sabre fighter and the B-52 bomber. The prototype was a proof-of-concept aircraft for both military and civilian use. The United States Air Force was the first customer, using it as the basis for the KC-135 Stratotanker aerial refueling platform. Whether the passenger

title: "Boeing 707" content: 707 would be profitable was far from certain. At the time, Boeing was making nearly all of its money from military contracts: Its last passenger transport, the Boeing 377 Stratocruiser, had netted the company a $15 million loss before it was purchased by the Air Force as the KC-97 Stratofreighter. In a demonstration flight over Lake Washington outside Seattle, on August 7, 1955, test pilot Tex Johnston performed a barrel roll in the 367-80 prototype. The 132-inch (3.35 m) wide fuselage of the Dash 80 was large enough for four-abreast (two-plus-two) seating like the Stratocruiser. Answering customers' demands and under

title: "Boeing 707" content: Douglas competition, Boeing soon realized this would not provide a viable payload, so it widened the fuselage to to allow five-abreast seating and use of the KC-135's tooling. Douglas Aircraft had launched its DC-8 with a fuselage width of . The airlines liked the extra space and six-abreast seating, so Boeing increased the 707's width again to compete, this time to . The first flight of the first-production 707-120 took place on December 20, 1957, and FAA certification followed on September 18, 1958. Both test pilots Joseph John "Tym" Tymczyszyn and James R. Gannett were awarded the first Iven C.

title: "Boeing 707" content: Kincheloe Award for the test flights that led to certification. A number of changes were incorporated into the production models from the prototype. A Krueger flap was installed along the leading edge between the inner and outer engines on early 707-120 and −320 models. The initial standard model was the 707-120 with JT3C turbojet engines. Qantas ordered a shorter-bodied version called the 707-138, which was a −120 with six fuselage frames removed, three in front of the wings, and three aft. The frames in the 707 were each 20 in (500 mm) apart, so this resulted in a net shortening

title: "Boeing 707" content: of 10 ft (3 m) to . Because the maximum takeoff weight remained the same as that of the −120 (247,000 lb or 112 t), the −138 was able to fly the longer routes that Qantas needed. Braniff International Airways ordered the higher-thrust version with Pratt & Whitney JT4A engines, the 707-220. The final major derivative was the 707-320, which featured an extended-span wing and JT4A engines, while the 707-420 was the same as the −320, but with Conway turbofan engines. British certification requirements relating to go-arounds with one engine inoperative also forced Boeing to increase the height of the

title: "Boeing 707" content: tail fin on all 707 variants, as well as add a ventral fin, which was retrofitted on earlier −120 and −220 aircraft. These modifications also aided in the mitigation of Dutch roll by providing more stability in yaw. Though initially fitted with turbojet engines, the dominant engine for the Boeing 707 family was the Pratt & Whitney JT3D, a turbofan variant of the JT3C with lower fuel consumption and higher thrust. JT3D-engined 707s and 720s were denoted with a "B" suffix. While many 707-120Bs and -720Bs were conversions of existing JT3C-powered machines, 707-320Bs were available only as newly built aircraft,

title: "Boeing 707" content: as they had a stronger structure to support a maximum takeoff weight increased by , along with modifications to the wing. The 707-320B series enabled nonstop westbound flights from Europe to the US West Coast and from the US to Japan. The final 707 variant was the 707-320C, (C for "Convertible"), which had a large fuselage door for cargo. It had a revised wing with three-sectioned leading-edge flaps, improving takeoff and landing performance and allowing the ventral fin to be removed (although the taller fin was retained). The 707-320Bs built after 1963 used the same wing as the −320C and

title: "Boeing 707" content: were known as 707-320B Advanced aircraft. Production of the passenger 707 ended in 1978. In total, 1,010 707s were built for civilian use, though many of these found their way to military service. The 707 production line remained open for purpose-built military variants until 1991, with the last new-build 707 airframes built as E-3 and E-6 aircraft. Traces of the 707 are still found in the 737, which uses a modified version of the 707's fuselage, as well as the same external nose and cockpit configurations as those of the 707. These were also used on the previous 727, while

title: "Boeing 707" content: the 757 also used the 707 fuselage cross-section. The 707's wings are swept back at 35°, and like all swept-wing aircraft, display an undesirable "Dutch roll" flying characteristic that manifests itself as an alternating yawing and rolling motion. Boeing already had considerable experience with this on the B-47 and B-52, and had developed the yaw damper system on the B-47 that would be applied to later swept-wing configurations like the 707. However, many novice 707 pilots had no experience with this phenomenon, as they were transitioning from straight-wing propeller-driven aircraft such as the Douglas DC-7 and Lockheed Constellation. On one

title: "Boeing 707" content: customer-acceptance flight, where the yaw damper was turned off to familiarize the new pilots with flying techniques, a trainee pilot's actions violently exacerbated the Dutch roll motion and caused three of the four engines to be torn from the wings. The plane, a brand new 707-227, "N7071", destined for Braniff, crash-landed on a river bed north of Seattle at Arlington, Washington, killing four of the eight occupants. In his autobiography, test pilot Johnston describes a Dutch roll incident he experienced as a passenger on an early commercial 707 flight. As the aircraft's movements did not cease and most of the

title: "Boeing 707" content: passengers became ill, he suspected a misrigging of the directional autopilot (yaw damper). He went to the cockpit and found the crew unable to understand and resolve the situation. He introduced himself and relieved the ashen-faced captain who immediately left the cockpit feeling ill. Johnston disconnected the faulty autopilot and manually stabilized the plane "with two slight control movements". The 707 uses engine-driven turbocompressors to supply pressurized air for cabin pressurization. On many commercial 707s, the outer port (number 1) engine mount is distinctly different from the other three, as this engine is not fitted with a turbocompressor. Later-model 707s

title: "Boeing 707" content: typically had this configuration, although American Airlines had turbocompressors on engines 2 and 3 only. Early 707 models often had turbocompressor fairings on all four engines, but with only two or three compressors installed. The JT3D-3B engines are readily identifiable by the large gray secondary air inlet doors in the nose cowl. These doors are fully open (sucked in at the rear) during takeoff to provide additional air. When the engines are throttled back to cruise, the doors are shut. The 707 was the first commercial jet aircraft to be fitted with clamshell-type thrust reversers on each of the four

title: "Boeing 707" content: engines. Pratt & Whitney, in a joint venture with Seven Q Seven (SQS) and Omega Air, has selected the JT8D-219 as a re-engine powerplant for Boeing 707-based aircraft, calling their modified configuration a 707RE. Northrop Grumman has selected the −219 to re-engine the United States Air Force's fleet of 19 E-8 Joint STARS aircraft, which will allow the J-STARS more time on station due to the engine's greater fuel efficiency. NATO also plans to re-engine their fleet of E-3 Sentry AWACS aircraft. The −219 is publicized as being half the cost of the competing 707 re-engine powerplant, the CFM International

title: "Boeing 707" content: CFM56, and is 40 dB quieter than JT3D engines that are being replaced. The first commercial orders for the 707 came on October 13, 1955, when Pan Am committed to 20 707s and 25 Douglas DC-8s, dramatically increasing their passenger capacity (in available revenue passenger seat-miles per hour/per day) over its existing fleet of propeller aircraft. The competition between the 707 and Douglas DC-8 was fierce. Pan American ordered these planes, when and as they did, so that they would be the operators of the "first-off" production line for each aircraft type. Until their initial batch of the aircraft had

title: "Boeing 707" content: been delivered to them and put into operation, Pan American would have the distinction of being not only the "Launch Customer" for both transcontinental American jets, but the exclusive operator of American intercontinental jet transports for at least a year. The only rival in intercontinental jet aircraft production at the time was the British de Havilland Comet. However, this was never real competition for the American market as the Comet series had been the subject of fatal accidents (due to design flaws) early in its introduction, withdrawn from service, virtually redesigned from scratch, and reintroduced as version -4. It was

title: "Boeing 707" content: also smaller and slower than the 707. Several major airlines committed only to the (second place in the production race) Douglas DC-8. Douglas Aircraft was the more established and preferred (by airlines and their passengers) maker of passenger aircraft at the time. Douglas had correctly decided to await the validation of a larger and more fuel efficient engine (JT4A from Pratt & Whitney), and to design a larger and longer range aircraft around this engine. To stay competitive, Boeing made a late and costly decision to redesign and enlarge the 707's wing to help increase range and payload. The new

title: "Boeing 707" content: version was numbered 707-320. Pan Am was the first airline to operate the 707; the carrier inaugurated 707 service with a christening at National Airport on October 17, 1958, attended by President Eisenhower, followed by a transatlantic flight for VIPs (personal guests of founder Juan Trippe) from Baltimore's Friendship International Airport to Paris. The aircraft's first commercial flight was from Idlewild Airport, New York, to Le Bourget, Paris, on October 26, 1958, with a fuel stop in Gander, Newfoundland. In December, National Airlines operated the first U.S. domestic jet airline flights between New York/Idlewild and Miami, using 707s leased from

title: "Boeing 707" content: Pan Am; American Airlines was the first domestic airline to fly its own jets, on January 25, 1959. TWA started domestic 707-131 flights in March and Continental Airlines started 707-124 flights in June; airlines that had ordered only the DC-8, such as United, Delta, and Eastern, were left without jets until September and lost market share on transcontinental flights. Qantas was the first non-US airline to use the 707s, starting in 1959. The 707 quickly became the most popular jetliner of its time. Its popularity led to rapid developments in airport terminals, runways, airline catering, baggage handling, reservations systems, and

title: "Boeing 707" content: other air transport infrastructure. The advent of the 707 also led to the upgrading of air traffic control systems to prevent interference with military jet operations. As the 1960s drew to a close, the exponential growth in air travel led to the 707 being a victim of its own success. The 707 was now too small to handle the increased numbers of passengers on the routes for which it was designed. Stretching the fuselage was not a viable option because the installation of larger, more powerful engines would need a larger undercarriage, which was not feasible given the design's limited

title: "Boeing 707" content: ground clearance at takeoff. Boeing's answer to the problem was the first wide-body airliner—the Boeing 747. The 707's first-generation engine technology was also rapidly becoming obsolete in the areas of noise and fuel economy, especially after the 1973 oil crisis. In 1982, during the Falklands War, the Argentine Air Force extensively used 707s for long-range maritime patrol, with some of them being intercepted and shepherded away by Royal Navy Sea Harriers, it also led to the conversion of British Nimrods to carry Sidewinder air-to-air missiles after a casual encounter. Trans World Airlines flew the last scheduled 707 flight for passengers

title: "Boeing 707" content: by a US carrier on October 30, 1983, although 707s remained in scheduled service by airlines from other nations for much longer. Middle East Airlines of Lebanon flew 707s and 720s in front-line passenger service until the end of the 1990s. Since LADE of Argentina took its 707-320Bs from regular service in 2007, Saha Airlines of Iran was the last airline to keep 707s in scheduled passenger service until April 2013. Operations of the 707 were threatened by the enactment of international noise regulations in 1985. Shannon Engineering of Seattle developed a hush kit with funding from Tracor, Inc, of

title: "Boeing 707" content: Austin, Texas. By the late 1980s, 172 Boeing 707s had been equipped with the Quiet 707 package. Boeing acknowledged that more 707s were in service than before the hush kit was available. Most remaining 707s are in freighter form, or as business jets. Although certified as Series 100s, 200s, 300s, etc., the different 707 variants are more commonly known as Series 120s, 220s, 320s, and so on, where the "20" part of the designation is Boeing's "customer number" for its development aircraft. The 707-020 was the original designation for what ultimately became the Boeing 720. Launch customer United Air Lines

title: "Boeing 707" content: was a Douglas DC-8 customer and preferred not to be seen as buying the competing 707, hence the 720 designation. American Airlines always referred to its 720s as 707s. The 707-120 was the first production 707 variant, with a longer, wider fuselage, and greater wingspan than the Dash 80. The cabin had a full set of rectangular windows and could seat up to 189 passengers. It was designed for transcontinental routes, and often required a refueling stop when flying across the North Atlantic. It had four Pratt & Whitney JT3C-6 turbojets, civilian versions of the military J57, initially producing 13,000

title: "Boeing 707" content: lb (57.8 kN) with water injection. Maximum takeoff weight was 247,000 lb and first flight was on December 20, 1957. Major orders were the launch order for 20 707-121 aircraft by Pan Am and an American Airlines order for 30 707-123 aircraft. The first revenue flight was on October 26, 1958; 56 were built, plus seven short-bodied −138s; the last −120 was delivered to Western in May 1960. The 707-138 was a −120 with a fuselage 10 ft shorter than the others, with 5 ft (three frames) removed ahead and behind the wing, giving increased range. Maximum takeoff weight was

title: "Boeing 707" content: the same 247,000 lb as the standard version. It was a variant for Qantas, thus had its customer number 38. The seven −138s were delivered to Qantas June–September 1959 and first carried passengers that July. The 707-120B had Pratt & Whitney JT3D-1 turbofan engines, which were quieter, more powerful, and more fuel-efficient, producing each, with the later JT3D-3 version giving . (This thrust did not require water injection, eliminating both the system and 5000–6000 lb of water.) The −120B had the wing modifications introduced on the 720 and a longer tailplane; a total of 72 were built, 31 for American

title: "Boeing 707" content: and 41 for TWA, plus six short-bodied −138Bs for Qantas. American had its 23 surviving −123s converted to 123Bs, but TWA did not convert its 15 -131s. The only other conversions were Pan American's five surviving −121s and one surviving −139, the three aircraft delivered to the USAF as −153s and the seven short-bodied Qantas −138s. The first flight of the −120B was on June 22, 1960, and American carried the first passengers in March 1961; the last delivery was to American in April 1969. Maximum weight was 258,000 lb (117,025 kg) for both the long- and short-bodied versions. The

title: "Boeing 707" content: 707-220 was designed for hot and high operations with more powerful 15,800 lb (70.3 kN) Pratt & Whitney JT4A-3 turbojets. Five of these were produced, but only four were ultimately delivered, with one being lost during a test flight. All were for Braniff International Airways and carried the model number 707-227; the first entered service in December 1959. This version was made obsolete by the arrival of the turbofan-powered 707-120B. The 707-320 Intercontinental is a stretched version of the turbojet-powered 707-120, initially powered by JT4A-3 or JT4A-5 turbojets producing 15,800 lb (70.3 kN) each (most eventually got 17,500 lb (78.4

title: "Boeing 707" content: kN) JT4A-11s). The interior allowed up to 189 passengers, the same as the -120 and -220 series, but improved two-class capacity due to an 80-in fuselage stretch ahead of the wing (from to ), with extensions to the fin and horizontal stabilizer extending the aircraft's length further. The longer wing carried more fuel, increasing range by and allowing the aircraft to operate as true transoceanic aircraft. The wing modifications included outboard and inboard inserts, as well as a kink in the trailing edge to add area inboard. Takeoff weight was increased to initially and to with the higher-rated JT4As and

title: "Boeing 707" content: center section tanks. Its first flight was on January 11, 1958; 69 turbojet 707-320s were delivered through January 1963, the first passengers being carried (by Pan Am) in August 1959. The 707-420 was identical to the −320, but fitted with Rolls-Royce Conway 508 (RCo.12) turbofans (or by-pass turbojets as Rolls-Royce called them) of 18,000 lb (79 kN) thrust each. The first announced customer was Lufthansa. BOAC's controversial order was announced six months later, but the British carrier got the first service-ready aircraft off the production line. The British Air Registration Board refused to give the aircraft a certificate of airworthiness,

title: "Boeing 707" content: citing insufficient lateral control, excessive rudder forces, and the ability to over-rotate on takeoff, stalling the wing on the ground (a fault of the de Havilland Comet 1). Boeing responded by adding 40 inches to the vertical stabilizer, applying full instead of partial rudder boost, and fitting an underfin to prevent over-rotation. These modifications except to the fin under the tail became standard on all 707 variants and were retrofitted to all earlier 707s. The 37 -420s were delivered to BOAC, Lufthansa, Air-India, El Al, and Varig through November 1963; Lufthansa was the first to carry passengers, in March 1960.

title: "Boeing 707" content: The 707-320B had the application of the JT3D turbofan to the Intercontinental, but with aerodynamic refinements. The wing was modified from the −320 by adding a second inboard kink, a dog-toothed leading edge, and curved low-drag wingtips instead of the earlier blunt ones. These wingtips increased overall wingspan by 3.0 ft. Takeoff gross weight was increased to . The 175 707-320B aircraft were all new-build; no original −320 models were converted to fan engines in civilian use. First service was June 1962, with Pan Am. The 707-320B Advanced is an improved version of the −320B, adding the three-section leading-edge flaps

title: "Boeing 707" content: already seen on the −320C. These reduced takeoff and landing speeds and altered the lift distribution of the wing, allowing the ventral fin found on earlier 707s to be deleted. From 1965, -320Bs had the uprated −320C undercarriage allowing the same MTOW. These were often identified as 707-320BA-H. The 707-320C has a convertible passenger–freight configuration, which became the most widely produced variant of the 707. The 707-320C added a strengthened floor and a new cargo door to the −320B model. The wing was fitted with three-section leading-edge flaps which allowed the deletion of the underfin. Three hundred and thirty-five of

title: "Boeing 707" content: these variants were built, including a small number with JT3D-7 engines (19,000 lb or 84.6 kN takeoff thrust) and a takeoff gross weight of . Ironically, most −320Cs were delivered as passenger aircraft, airlines hoping that the cargo door would increase second-hand values. The addition of two additional emergency exits, one on either side aft of the wing raised the maximum passenger capacity to a theoretical 219. Only a few aircraft were delivered as pure freighters. One of the final orders was by the Iranian Government for 14 707-3J9C aircraft capable of VIP transportation, communication, and in-flight refuelling tasks. The

title: "Boeing 707" content: 707-700 was a test aircraft used to study the feasibility of using CFM International CFM56 engines on a 707 airframe and possibly retrofitting existing aircraft with the engine. After testing in 1979, "N707QT", the last commercial 707 airframe, was restored to 707-320C configuration and delivered to the Moroccan Air Force as a tanker aircraft via a "civilian" order. Boeing abandoned the retrofit program, since it felt it would be a threat to the Boeing 757 program. The information gathered from testing led to the eventual retrofitting of CFM56 engines to the USAF C-135/KC-135R models, and some military versions of the

title: "Boeing 707" content: 707 also used the CFM56. The Douglas DC-8 "Super 70" series with CFM56 engines was developed and extended the DC-8's life in a stricter noise regulatory environment. So, more DC-8s than 707s are in service now. The 707-620 was a proposed domestic range-stretched variant of the 707-320B. The 707-620 was to carry around 200 passengers while retaining several aspects of the 707-320B. It would have been delivered around 1968 and would have also been Boeing's answer to the stretched Douglas DC-8 Series 60. Had the 707-620 been built, it would have cost around US$8,000,000. However, engineers discovered that a longer

title: "Boeing 707" content: fuselage and wing meant a painstaking redesign of the wing and landing-gear structures. Rather than spend money on upgrading the 707, engineer Joe Sutter stated the company "decided spending money on the 707 wasn't worth it". The project was cancelled in 1966 in favor of the newer Boeing 747. The 707-820 was a proposed intercontinental stretched variant of the 707-320B. It was to be powered by four Pratt & Whitney JT3D-15 turbofan engines and would have had a extension in wingspan. Two variations were proposed, the 707-820(505) model and the 707-820(506) model. The 505 model would have had a fuselage

title: "Boeing 707" content: longer than the 707-320B and would have carried 209 passengers in mixed-class configuration and 260 passengers in all-economy configuration. The 506 model would have had a fuselage longer than the 707-320B and would have carried 225 passengers in mixed class configuration and 279 passengers in all economy configuration. Like the 707-620, the 707-820 was also set to compete with the stretched DC-8s. The design was being pitched to American, TWA, BOAC, and Pan Am at the time of its proposal in early 1965. The 707-820 would have cost US$10,000,000. Like the 707-620, the 707-820 would have required a massive structural

title: "Boeing 707" content: redesign to the wing and gear structures. The 707-820 was also cancelled in 1966 in favor of the 747. The militaries of the US and other countries have used the civilian 707 aircraft in a variety of roles, and under different designations. (The 707 and U.S. Air Force's KC-135 were developed in parallel from the Boeing 367–80 prototype.) The Boeing E-3 Sentry is a US military airborne warning and control system (AWACS) aircraft based on the Boeing 707 that provides all-weather surveillance, command, control, and communications. The VC-137C variant of the Stratoliner was a special-purpose design meant to serve as

title: "Boeing 707" content: Air Force One, the secure transport for the President of the United States. These models were in operational use from 1962 to 1990. The two aircraft remain on display: SAM 26000 is at the National Museum of the United States Air Force near Dayton, Ohio and SAM 27000 is at the Ronald Reagan Presidential Library in Simi Valley, California. The Canadian Forces also operated the Boeing 707 with the designation CC-137 Husky (707-347C) from 1971 to 1997. Boeing 717 was the company designation for C-135 Stratolifter and KC-135 Stratotanker derivatives of the 367-80. The designation was later reused in renaming

title: Marimba content: Marimba The marimba () is a percussion instrument consisting of a set of wooden bars struck with yarn or rubber mallets to produce musical tones. Resonators or pipes suspended underneath the bars amplify their sound. The bars of a chromatic marimba are arranged like the keys of a piano, with the groups of two and three accidentals raised vertically, overlapping the natural bars to aid the performer both visually and physically. This instrument is a type of idiophone, but with a more resonant and lower-pitched tessitura than the xylophone. A person who plays the marimba is called a "marimbist" or

title: Marimba content: a "marimba player". Modern uses of the marimba include solo performances, woodwind and brass ensembles, marimba concertos, jazz ensembles, marching band (front ensembles), drum and bugle corps, and orchestral compositions. Contemporary composers have used the unique sound of the marimba more and more in recent years. Xylophones are widely used in music of west and central Africa. In Latin America, enslaved Africans recreated them in the 16th and 17th centuries. The name "marimba" stems from Bantu "marimba" or "malimba", 'xylophone'. According to some Western sources, the word 'marimba' is formed from "ma" 'many' and "rimba" 'single-bar xylophone,' however the use

title: Marimba content: of the term marimba and/or derivative terms is not present in any West African language. The instrument itself is present, but is called balafon or heri in Mali and/or Guinea, while it is known as gyil among the Akan peoples in and around Ghana. The word marimba and derivative words is used widely in East, Central and Southern Africa. A survey of the literature on the African marimba and related instruments, like the Xylorimba, likembe and ilimba indicate a relationship between the word marimba and the various lamellaphones found all over Central and East Africa. Other sources credit the creation

title: Marimba content: of the marimba and the kalimba to Queen Marimba of the Wakambi people, who live south of Lake Victoria. In the Shona language "imba" means song. Kuimba is to sing. Marimba, is said to be the "mother of song" and the creator of all the instruments, including the marimba. Mama means mother in Kiswahili, so it makes perfect sense that the word mother would be combined with the word "imba" which is the unconjugated verb for 'sing'. The karimba is also said to have been created by Queen Marimba. In much of East & Central Africa the karimba is seen

title: Marimba content: as a hand-held version of the marimba. Diatonic xylophones were introduced to Central America in the 16th or 17th century. The first historical record of Mayan musicians using gourd resonator marimbas in Guatemala was made in 1680, by the historian . It became more widespread during the 18th and 19th centuries, as Mayan and Ladino ensembles started using it on festivals. In 1821, the marimba was proclaimed the national instrument of Guatemala in its independence proclamation. In 1850, Mexican marimbist Manuel Bolán Cruz (1810-1863), modified the old bow marimba, by the wooden straight one, lengthening the legs so that the

title: Marimba content: musicians could play in a standing mode, expanded the keyboard and replaced the gourd resonators by wooden boxes. In 1892, Mexican musician expanded marimba to include the chromatic scale by adding another row of sound bars, akin to black keys on the piano. The name "marimba" was later applied to the orchestra instrument inspired by the Latin American model. In the United States, companies like Deagan and Leedy company adapted the Latin American instruments for use in western music. Metal tubes were used as resonators, fine-tuned by rotating metal discs at the bottom; lowest note tubes were U-shaped. The marimbas

title: Marimba content: were first used for light music and dance, such as Vaudeville theater and comedy shows. Clair Omar Musser was a chief proponent of marimba in the United States at the time. French composer Darius Milhaud made the ground-breaking introduction of marimbas into Western classical music in his 1947 "Concerto for Marimba and Vibraphone". Four-mallet grip was employed to play chords, enhancing interest for the instrument. In the late 20th century, modernist and contemporary composers found new ways to use marimba: notable examples include Leoš Janáček ("Jenufa"), Carl Orff ("Antigonae"), Karl Amadeus Hartmann, Hans Werner Henze ("Elegy for Young Lovers"), Pierre

title: Marimba content: Boulez ("Le marteau sans maître") and Steve Reich. Marimba bars are typically made of either wood or synthetic material. Rosewood is the most desirable, while Padauk is a popular affordable alternative. Bars made from synthetic materials generally fall short in sound quality in comparison to wooden bars, but are less expensive and yield added durability and weather resistance, making them suitable for outdoor use; marimbas with wooden bars are usually played inside because the bars are susceptible to pitch change due to weather. Bubinga ("Guibourtia demeusei") and mahogany have also been cited as comparable to rosewood in quality for use

title: Marimba content: as marimba bars. The specific rosewood, "Dalbergia stevensonii", only grows in Southern Guatemala and Belize, formerly the British Honduras. This wood has a Janka rating of 2200, which is about three times harder than Silver Maple. The bars are wider and longer at the lowest pitched notes, and gradually get narrower and shorter as the notes get higher. During the tuning, wood is taken from the middle underside of the bar to lower the pitch. Because of this, the bars are also thinner in the lowest pitch register and thicker in the highest pitch register. In Africa, most marimbas are

title: Marimba content: made by local artisans from locally available materials. Marimba bars produce their fullest sound when struck just off center, while striking the bar in the center produces a more articulate tone. On chromatic marimbas, the accidentals ("black keys") can also be played on the extreme front edge of the bar, away from the node (the place where the string goes through the bar) if necessary. Playing on the node produces a sonically weak tone, and the technique is only used when the player or composer is looking for a muted sound from the instrument. There is no standard range of

title: Marimba content: the marimba, but the most common ranges are 4.3 octaves, 4.5 octaves and 5 octaves; 4, 4.6 and 5.5 octave sizes are also available. The range of the marimba has been gradually expanding, with companies like Marimba One adding notes up to F above the normal high C (C) on their 5.5 octave instrument, or marimba tuners adding notes lower than the low C on the 5 octave C. Adding lower notes is somewhat impractical; as the bars become bigger and the resonators become longer, the instrument must be taller and the mallets must be heavier in order to produce

title: Marimba content: a tone rather than just a percussive attack. Adding higher notes is also impractical because the hardness of the mallets required to produce the characteristic tone of a marimba are much too hard to play with in almost any other, lower range on the instrument. The marimba is a non-transposing instrument with no octave displacement, unlike the xylophone which sounds one octave higher than written and the glockenspiel which sounds two octaves higher than written. Part of the key to the marimba's rich sound is its resonators. These are tubes (usually aluminum) that hang below each bar. In the most

title: Marimba content: traditional versions, various sizes of natural gourds are attached below the keys to act as resonators; in more sophisticated versions carved wooden resonators are substituted, allowing for more precise tuning of pitch. In Central America and Mexico, a hole is often carved into the bottom of each resonator and then covered with a delicate membrane taken from the intestine of a pig to add a characteristic "buzzing" or "rattling" sound known as "charleo". In more contemporary-style marimbas, wood is replaced by PVC tubing. The holes in the bottoms of the tubes are covered with a thin layer of paper to

title: Marimba content: produce the buzzing noise. The length of the resonators varies according to the frequency that the bar produces. Vibrations from the bars resonate as they pass through the tubes, which amplify the tone in a manner very similar to the way in which the body of a guitar or cello would. In instruments exceeding octaves, the length of tubing required for the bass notes exceeds the height of the instrument. Some manufacturers, such as DeMorrow and Malletech, compensate for this by bending the ends of the tubes. This involves soldering smaller straight sections of tubes to form "curved" tubes. Both

title: Marimba content: DeMorrow and Malletech use brass rather than aluminium. Others, such as Adams and Yamaha, expand the tubes into large box-shaped bottoms, resulting in the necessary amount of resonating space without having to extend the tubes. This result is achieved by the custom manufacturer Marimba One by widening the resonators into an oval shape, with the lowest ones reaching nearly a foot in width, and doubling the tube up inside the lowest resonators. Resonator tuning involves adjusting "stops" in the tubes themselves to compensate for temperature and humidity conditions in the room where the instrument is stored. Some companies offer adjustment

title: Marimba content: in the upper octaves only. Others do not have any adjustable stops. Still some companies (Malletech and DeMorrow) offer full range adjustable stops. On many marimbas, decorative resonators are added to fill the gaps in the accidental resonator bank. In addition to this, the resonator lengths are sometimes altered to form a decorative arch, such as in the Musser M-250. This does not affect the resonant properties, because the end plugs in the resonators are still placed at their respective lengths. The mallet shaft is commonly made of wood, usually birch, but may also be rattan or fiberglass. The most

title: Marimba content: common diameter of the shaft is around . Shafts made of rattan have a certain elasticity to them, while birch has almost no give. Professionals use both depending on their preferences, whether they are playing with two mallets or more, and which grip they use if they are using a four-mallet grip. Appropriate mallets for the instrument depend on the range. The material at the end of the shaft is almost always a type of rubber, usually wrapped with yarn. Softer mallets are used at the lowest notes, and harder mallets are used at the highest notes. Mallets that are

title: Marimba content: too hard will damage the instrument, and mallets that might be appropriate for the upper range could damage the notes in the lower range (especially on a padouk or rosewood instrument). On the lower notes, the bars are larger, and require a heavier mallet to bring out a strong fundamental. Because of the need to use varying hardnesses of mallets, some players, when playing with four or more mallets, might use graduated mallets to match the bars that they are playing (softer on the left, harder on the right). Some mallets, called "two-toned" or "multi-tonal", have a hard core, loosely

title: Marimba content: wrapped with yarn. These are designed to sound articulate when playing at a loud dynamic, and broader at the quieter dynamics. Modern marimba music calls for simultaneous use of between two and four mallets (sometimes up to six or eight), granting the performer the ability to play chords or music with large interval skips more easily. Multiple mallets are held in the same hand using any of a number of techniques or "grips". For two mallets in each hand, the most common grips are the Burton grip (made popular by Gary Burton), the Traditional Grip (or "cross grip") and the

title: Marimba content: Musser-Stevens grip (made popular by Leigh Howard Stevens). Each grip is perceived to have its own benefits and drawbacks. For example, some marimbists feel the Musser-Stevens grip is more suitable for quick interval changes and mallet independence, while the Burton grip is more suitable for stronger playing or switching between chords and single-note melody lines. The Traditional Grip gives a greater dynamic range and freedom of playing. The choice of grip varies by region (the Musser-Stevens grip and the Burton grip are more popular in the United States, while the traditional grip is more popular in Japan), by instrument (the

title: Marimba content: Burton grip is less likely to be used on marimba than on a vibraphone) and by the preference of the individual performer. Six-mallet grips consist of variations on these three grips. Six mallet marimba grips have been used for years by Mexican and Central American marimbists, but they are generally considered non-standard in the Western classical canon. Keiko Abe has written a number of compositions for six mallets, including a section in her concerto "Prism Rhapsody". Other marimbists/composers using this technique include Rebecca Kite (who commissioned composer Evan Hause to write Circe, a major work for six mallets, in 2001),

title: Marimba content: Dean Gronemeier, Robert Paterson, and Kai Stensgaard. Paterson's grip is based on the Burton grip, and his grip and technique have been called the Paterson grip, and even the Wolverine grip. Paterson states that his technique differs from others in that there is less emphasis places on block chords on the lower bank of notes (the naturals or white notes) and more emphasis on independence, one-handed rolls, and alternations between mallets 12-3 or 1-23 in the left hand (or 45-6 or 4-56 in the right hand, respectively), and so on. In 2012, Paterson released the world's first all six-mallet marimba

title: Marimba content: album entitled Six Mallet Marimba, demonstrating these techniques via works Paterson has written. Ludwig Albert published at first a work for 8 mallets and demonstrated the Ludwig Albert 8 mallet grip based on the traditional grip from 1995. This list represents an incomplete selection of Western classical compositions for the instrument: Traditional marimba bands are especially popular in Guatemala where they are the national symbol of culture, but are also strongly established in the Mexican states of Chiapas, Tabasco and Oaxaca. They are also very popular in other Central American nations like Honduras, El Salvador, Nicaragua and Costa Rica, as

title: Marimba content: well as among Afro-Ecuadorians and Afro-Colombians. There have been numerous jazz vibraphonists who also played the marimba. Notable among them are Gary Burton, David Friedman, Stefon Harris, Bobby Hutcherson, Joe Locke, Steve Nelson, Red Norvo, Dave Pike, Gloria Parker, Dave Samuels and Arthur Lipner. Marimbaist and vibraphonist Julius Wechter was the leader of a popular 1960s Latin-flavored band called Baja Marimba Band and Herb Alpert and his Tijuana Brass made frequent use of the marimba. Marimba was played famously by Brian Jones in the Rolling Stones' songs "Under My Thumb" and "Out of Time". "Island Girl" by Elton John and

Art Tripp played the marimba on several of Captain Beefheart & the Magic Band's albums, most notably on "Lick My Decals Off, Baby" and "The Spotlight Kid". Victor Feldman played the marimba on several of Steely Dan's early albums. It is played at the start of "Mamma Mia" by ABBA. One of the most popular songs to feature a marimba is "Shape of You" by Ed Sheeran, where marimba is part of the tropical house effects,

title: Marimba content: and The Psychedelic Furs 1982 song "Love My Way" which features the marimba, originally played by Todd Rundgren, throughout. It is also featured on Toto's 1982 hit song "Africa." Percussionist Evelyn Glennie has collaborated with Björk and can be heard playing the marimba on "Post" and "Telegram", as well as "Oxygen". Thompson Twins included marimba in their many 1980s works. Jack White played marimba on "The Nurse", a song on The White Stripes' album "Get Behind Me Satan". In 2003, Marina Calzado Linage recorded an album bridging the gap between academic and popular music, "Marimba de Buenos Aires", featuring music

title: Marimba content: by Ástor Piazzolla. In 2009, Canadian musician Spencer Krug, working under the moniker Moonface, released a 20-minute continuous piece called "Dreamland EP: Marimba And Shit-Drums" with Jagjaguwar. The recording consists entirely of marimba, drums and vocals and comprises many movements and recurring themes. Vincent Montana Jr. played the marimba on one of the great socially conscious soul songs of the early 1970s "People Make the World Go Round" by The Stylistics. The experimental band Coil (band) used the marimba in its later performances such as Selvaggina, Go Back into the Woods and studio albums The Ape of Naples and Black

title: Marimba content: Antlers. The flapamba is a musical instrument in the percussion family. It consists of tuned wooden bars pinched on one side (over the node), and mounted over resonator boxes. Sliding the bars slightly forward or backward affects their tuning. Unlike marimba or xylophone however, the sound is not as focused tonally, as it is a bit more percussive (closer to tuned log drums). Part of what makes the flapamba’s characteristic sound is the tuning; for instance, the resonators are not tuned to the bars as in other standard keyboard percussion instruments. Renowned studio percussionist Emil Richards bought his original flapamba

title: Marimba content: from Professional Drum Shop in Hollywood in the late 1960s or early 1970s, and added it to his giant instrument collection, the Emil Richards Collection. The staff at the store convinced him to buy it, as they told him that they were getting out of the percussion rental business since Emil was dominating much of the work in town. Emil couldn't find any info on the history or maker of the flapamba when he purchased it, but nevertheless he started using it on recording sessions, as the chromatic layout of the instrument made it an easy transition from other keyboard

title: Marimba content: mallet instruments. He used the softest mallets possible or the meat of the fingers to get a warm, resonant, wooden sound. This original flapamba had a range from middle C (C), up two full octaves. In the 2000s, Emil decided that he would like the flapamba to have an additional lower range, so specialty mallet craftsman Chris Banta made new bars spanning F to C, and dubbed this the "bass flapamba". He also replaced the bars on the original set to maintain continuity of sound between both sets, and changed the finish to a blonde color from the original set's

title: Marimba content: brown. Both sets combined have a range from F–C. Emil's flapamba has been heard on countless soundtracks and other recordings, such as on the television shows "Lost", "Daktari", and "Kung Fu". Elmer Bernstein used it on his soundtrack for "McQ". The beginning of the Steely Dan track "Rikki Don't Lose That Number" features Victor Feldman playing the flapamba, but his contribution was cut from the original ABC single version.

The 1 Series accounted for nearly one-fifth of the total BMW sales in 2008. Initially, BMW considered adopting the Rover R30 design program into the upcoming 1 Series, however it was eventually decided to develop the 1 Series alongside the E90 3 Series. The E81/E82/E87/E88 shares approximately 60% of components with the E90, including front and rear suspension, structure, chassis, powertrain, hardware and electronic elements. Design work was done by Christopher Chapman in 2001 under design director Chris Bangle. In

The first 1 Series production models - in the E87 five-door hatchback body style - were launched at the Paris Motor Show in September 2004. The chassis has a rear-wheel drive layout with a 50:50 weight balance, a longitudinally-mounted engine and aluminium multi-link suspension. The 1 Series was launched globally in September 2004 as the E87 five-door hatchback. The E87 was produced from 2004 until 2011, with the model range consisting of the 116i, 116d, 118i, 118d, 120i, 120d, 123d and 130i. Kerb Weight: 1340 kg.

Question: What is this lake named after?

Instruction: Obtain documents that correspond to the inquiry alongside the provided image:

title: "Lake Lucerne" content: Lake Lucerne Lake Lucerne (, literally "Lake of the Four Forested Settlements", , ) is a lake in central Switzerland and the fourth largest in the country. The lake has a complicated shape, with several sharp bends and four arms. It starts in the south-north bound Reuss Valley between steep cliffs above the "Urnersee" from Flüelen towards Brunnen to the north before it makes a sharp bend to the west where it continues into the "Gersauer Becken". Here is also the deepest point of the lake with . Even more west of it is the "Buochser Bucht", but the lake

title: "Lake Lucerne" content: sharply turns north again through the narrow opening between the "Unter Nas" (lower nose) of the Bürgenstock to the west and the "Ober Nas" (upper nose) of the Rigi to the east to reach the "Vitznauer Bucht". In front of Vitznau below the Rigi the lake turns sharply west again to reach the center of a four-arm cross, called the "Chrütztrichter" (Cross Funnel). Here converge the "Vitznauer Bucht" with the "Küssnachtersee" from the north, the "Luzernersee" from the west, and the "Horwer Bucht" and the "Stanser Trichter" to the south, which is to be found right below the northeast side

title: "Lake Lucerne" content: of the Pilatus and the west side of the Bürgenstock. At the very narrow pass between the east dropper of the Pilatus (called "Lopper") and Stansstad the lake reaches its southwestern arm at Alpnachstad on the steep southern foothills of the Pilatus, the "Alpnachersee". The lake drains its water into the Reuss in Lucerne from its arm called "Luzernersee" (which literally translates as "Lake of Lucerne"). The entire lake has a total area of 114 km² (44 sq mi) at an elevation of a.s.l., and a maximum depth of . Its volume is 11.8 km³. Much of the shoreline rises

title: "Lake Lucerne" content: steeply into mountains up to 1,500 m above the lake, resulting in many picturesque views including those of the mountains Rigi and Pilatus. The Reuss enters the lake at Flüelen, in the part called "Urnersee" ("Lake of Uri", in the canton of Uri) and exits at Lucerne. The lake also receives the Muota at Brunnen, the Engelberger Aa at Buochs, and the Sarner Aa at Alpnachstad. It is possible to circumnavigate the lake by train and road, though the railway route circumvents the lake even on the north side of the Rigi via Arth-Goldau. Since 1980, the A2 motorway leads

title: "Lake Lucerne" content: through the Seelisberg Tunnel in order to reach the route to the Gotthard Pass in just half an hour in Altdorf, Uri right south of the beginning of the lake in Flüelen. Steamers and other passenger boats ply between the different villages and towns on the lake. It is a popular tourist destination, both for native Swiss and foreigners, and there are many hotels and resorts along the shores. In addition, the meadow of the Rütli, traditional site of the founding of the Swiss Confederation, is on the "Urnersee" shore. A 35 km commemorative walkway, the Swiss Path, was built

title: "Lake Lucerne" content: around the Lake of Uri to celebrate the country's 700th anniversary in 1991. The name of "Vierwaldstättersee" is first used in the 16th century. The (three) "Waldstätte(n)" (lit.: "Forested Sites/Settlements") since the 14th century were the confederate allies of Uri, Schwyz and Unterwalden. The notion of "Four Waldstätten" ("Vier Waldstätten"), with the addition of the canton of Lucerne, is first recorded in the 1450s, in an addition to the "Silver Book" of Egloff Etterlin of Lucerne. Each part of the lake has it own designation: Lake Lucerne borders on the three original Swiss cantons of Uri, Schwyz, and Unterwalden (which

title: "Lake Lucerne" content: today is divided into the cantons of Obwalden and Nidwalden), as well as the canton of Lucerne, thus the name "Vierwaldstättersee" (lit.: Lake of the Four Forested Settlements). Many of the oldest communities of Switzerland are along the shore, including Küssnacht, Weggis, Vitznau, Gersau, Brunnen, Altdorf, Buochs, and Treib. Lake Lucerne is singularly irregular and appears to lie in four different valleys, all related to the conformation of the adjoining mountains. The central portion of the lake lies in two parallel valleys whose direction is from west to east, the one lying north, the other south of the ridge of

title: "Lake Lucerne" content: the Bürgenstock. These are connected through a narrow strait, scarcely one kilometre wide, between the two rocky promontories called respectively "Unter Nas" and "Ober Nas" (Lower and Upper Nose). It is not unlikely that the southern of these two divisions of the lake—called "Buochser Bucht"—formerly extended to the west over the isthmus whereon stands the town of Stans, thus forming an island of the Bürgenstock. The west end of the main branch of the lake, whence a comparatively shallow bay extends to the town of Lucerne, is intersected obliquely by a deep trench whose south-west end is occupied by the

title: "Lake Lucerne" content: branch called "Alpnachersee", while the north-east branch forms the long arm of Küssnacht, "Küssnachtersee". These both lie in the direct line of a valley that stretches with scarcely a break in between the Uri Alps and the Emmental Alps. At the eastern end of the Gersauer Becken, where the containing walls of the lake-valley are directed from east to west, it is joined at an acute angle by the arm of Uri, or the "Urnersee", lying in the northern prolongation of the deep cleft that gives a passage to the Reuss, between the Uri Alps and the Glarus Alps. The

title: "Lake Lucerne" content: Urnersee occupies the northernmost and deep portion of the great cleft of the Reuss Valley, which has cut through the Alpine ranges from the St Gotthard Pass to the neighbourhood of Schwyz. From its eastern shore the mountains rise in almost bare walls of rock to a height of from above the water. The two highest summits are the Fronalpstock and the Rophaien (2078 m). Between them the steep glen or ravine of the Riemenstaldener Tal descends to Sisikon, the only village with Flüelen right on the shore on that side of the Urnersee. On the opposite or western shore,

title: "Lake Lucerne" content: the mountains attain still greater dimensions. The Niederbauen Chulm is succeeded by the Oberbauenstock, and farther south, above the ridge of the Scharti, appear the snowy peaks of the Gitschen and the Uri Rotstock (2,928 m). In the centre opens the Reuss Valley, backed by the rugged summits of the Urner and Glarner Alps. The breadth of these various sections of the lake is very variable, but is usually between one and two miles (3 km). The lake's surface, whose mean height above the sea is 434 metres, is the lowest point of the cantons of Uri, Obwalden and Nidwalden.

title: "Lake Lucerne" content: Originally the lake was susceptible to variations in level and flooding along its shoreline. Between 1859 and 1860, the introduction of a needle dam in the Reuss in the city of Lucerne, just upstream from the Spreuerbrücke, allowed the lake level to be stabilised. The culminating point of the lake's drainage basin, as well as Central Switzerland, is the Dammastock at 3,630 metres above sea level. The lake is navigable, and has formed an important part of Switzerland's transport system for many centuries, and at least since the opening of the first track across the Gotthard Pass in 1230. This

title: "Lake Lucerne" content: trade grew with the opening of a new mail coach road across the pass in 1830. This road had its northern terminus at Flüelen at the extreme eastern end of the lake, and the lake provided the only practical onward link to Lucerne, and hence the cities of northern Switzerland and beyond. Whilst the development of Switzerland's road and rail networks has relieved the lake of much of its through traffic, it continues to be used by a considerable number of vessels, both private and public. Much of this usage is tourist or leisure oriented, but the lake continues to

title: "Lake Lucerne" content: provide practical public and cargo transport links between the smaller lakeside communities. Passenger boats of the Schifffahrtsgesellschaft des Vierwaldstättersees (SGV) provide services on the lake, including many run by historic paddle steamers. The SGV serves 32 places along the shore of the lake, with interchange to both main line and mountain railways at various points. Under separate management, the Autofähre Beckenried-Gersau provides a car ferry service between Beckenried, on the south bank of the lake, and Gersau on the north. Cargo barges, to a local design known as "Nauen", are still used on the lake. Some have been converted for

title: "Lake Lucerne" content: use as party boats. Other barges are used by the gravel dredging industry that operates on the lake, using large dredgers to obtain sand and gravel for use in the construction industry. Beethoven's "Moonlight" Sonata derives its name from an 1832 description of the first movement by music critic Ludwig Rellstab, who compared it to moonlight shining upon Lake Lucerne. Gioacchino Rossini uses this in his "William Tell" Overture Section A: Sunrise over the Alps. Lake Lucerne has twice been used as a venue for the European Rowing Championships: in 1908 and then in 1926. The nearby Rotsee has since

Question: What is this animal named after?

Instruction: Extract documents linked to the question provided in conjunction with the image:

title: "Steller sea lion" content: Steller sea lion The Steller sea lion ("Eumetopias jubatus"), also known as the northern sea lion and Steller's sea lion, is a near-threatened species of sea lions in the northern Pacific. It is the sole member of the genus "Eumetopias" and the largest of the eared seals (Otariidae) and is also the largest sea lion. Among pinnipeds, it is inferior in size only to the walrus and the two elephant seals. The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades owing to

title: "Steller sea lion" content: significant, unexplained declines in their numbers over a large portion of their range in Alaska. Adult animals are lighter in colour than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Steller sea lion pups are born almost black, weighing around , and remain dark for several months. Females and males both grow rapidly until the fifth year, after which female growth slows considerably. Adult females measure in length, with an average of , and weigh , with an average of . Males continue to grow until their secondary sexual traits appear in their fifth to eighth

title: "Steller sea lion" content: year. Males are slightly longer than the females; they grow to about long, with an average of . Males have much wider chests, necks, and general forebody structure and weigh , with an average of . Males are further distinguished from females by broader, higher foreheads, flatter snouts, and a thick mane of coarse hair around their large necks. Indeed, their Latin name translates roughly as "maned one with the broad forehead". The range of the Steller sea lion extends from the Kuril Islands and the Sea of Okhotsk in Russia to the Gulf of Alaska in the north, and

title: "Steller sea lion" content: south to Año Nuevo Island off central California. They formerly bred as far south as the Channel Islands, but have not been observed there since the 1980s. Based on genetic anаlyses and local migration patterns, the global Steller sea lion population has traditionally been divided into an eastern and western stock at 144°W longitude, roughly through the middle of the Gulf of Alaska. Recent evidence suggests the sea lions in Russia in the Sea of Okhotsk and the Kuril Islands comprise a third Asian stock, while the sea lions on the eastern seaboard of Kamchatka and the Commander Islands belong

title: "Steller sea lion" content: to the western stock. In the summer, Steller sea lions tend to shift their range somewhat southward. Thus, though no reproductive rookeries are in Japan, several consistent haulouts are found around Hokkaidō in the winter and spring. Vagrants have been spotted in the Yellow Sea and Bohai Gulf and along the coast of Korea and China. Steller sea lions tend to live in the coastal waters of the subarctic because of the cooler temperate climate of the area. Like all otariids, Steller sea lions are amphibious and spend some time in water and some on land. Typically, Stellar sea lions

title: "Steller sea lion" content: spend their time in the water feeding but haul-out onto land to reproduce, raise their pups, molt, and rest. Steller sea lions usually congregate on isolated islands because they are the ideal terrestrial habitat. These isolated islands are preferred by Stellar sea lions because they can avoid predation from terrestrial predators, easily thermoregulate (cooling winds), and access offshore prey more easily. Some haul-out sites, known as rookeries, are commonly used for reproduction while other haul-out sites, nonbreeding sites, are used for other purposes like molting. However, biotic and abiotic factors can influence the amount of time that Steller sea lions

title: "Steller sea lion" content: spend on land. Haul-out sites and haul-out abundance of the Steller sea lion is determined by prey availability, predator abundance, tide levels, weather, etc. Steller sea lions are skilled and opportunistic marine predators, feeding on a wide range of fish and cephalopod species. Important diet components include walleye pollock, Atka mackerel, halibut, herring, capelin, flatfish Pacific cod, rockfish, sculpins, Salmon, Sand lance, cephalopods like squid and octopus. They seem to prefer schooling fish and remain primarily between intertidal zones and continental shelves. They usually aggregate in groups of 1-12, and aggregate in areas of prey abundance. They are known to

title: "Steller sea lion" content: aggregate near fishing vessels, preying on by catch discards. Most of the data on their foraging comes from data collected off the coast of Alaska, and their foraging behaviors globally are unknown. In addition to their primary marine environment, they are also known to enter estuarine environments and feed on some brackish-water fish such as sturgeon. Very occasionally, they have been known to prey on northern fur seals, harbor seals, and sea otter pups. It has been recorded that their prey variety has broadened overtime. Their diet composition varies seasonally and geographically. They are opportunistic predators, capitalizing on the most

title: "Steller sea lion" content: abundant prey species. Steller Sea Lions are top-level carnivores, but are susceptible to predation primarily by killer whales. Shark species are also a possible predator, sleeper sharks preying on juvenile sea lions, and also great white sharks. Reproductively mature male sea lions aggregate in May on traditional, well-defined reproductive rookeries, usually on beaches on isolated islands. The larger, older males establish and defend distinct territories on the rookery. A week or so later, adult females arrive, accompanied occasionally by sexually immature offspring, and form fluid aggregations throughout the rookery. Like all other otariids, Steller sea lions are polygynous. However, unlike

title: "Steller sea lion" content: some other species, they do not coerce individual females into harems, but control spatial territories among which females freely move about. Steller sea lions have used aquatic, semiaquatic, and terrestrial territories. Males with semiaquatic territories have the most success in defending them. The boundaries are defined by natural features, such as rocks, faults, or ridges in rocks, and territories can remain stable for 60 days. Though Steller sea lion males are generally tolerant of pups, one male filmed on Medny Island in Russia was documented killing and eating several pups in a first-ever recorded incident of cannibalism. Though researchers are

title: "Steller sea lion" content: uncertain as to the motives or reasons behind said attacks, it is suggested that the bull involved may have an abnormal personality akin to being psychotic. Pregnant females give birth soon after arriving on a rookery, and copulation generally occurs one to two weeks after giving birth, but the fertilized egg does not become implanted in the uterus until the fall. A fertilized egg may remain inside a female for up to three months before being implanted and beginning to form into a blastocyst. Twins are rare. After a week or so of nursing without leaving the rookery, females begin

title: "Steller sea lion" content: to take progressively longer and more frequent foraging trips, leaving their pups behind, until at some point in late summer the mother and pup both leave the rookery. This behavior is called the maternal attendance pattern and is common in otariids. As pups get older the amount of time spent by females foraging out at sea increases.This continues until pups obtain the ideal body weight and energy reserves in order to eat on their own. A study conducted by the University of California, Santa Cruz found that on average male pups consume more milk than females this may be due

title: "Steller sea lion" content: to the differences in sexual dimorphism common to otariids. Reproductive males fast throughout the reproductive season, often without entering the water once from mid May until August, when the structure of the reproductive rookeries begins to fall apart and most animals leave for the open seas and disperse throughout their range. The age at weaning is highly variable; pups may remain with their mothers for as long as four years. Incidents of mothers feeding daughters that are simultaneously feeding their own newborn pups have been documented, an extremely rare occurrence among mammals. A study done at Ano Nuevo in 1983

title: "Steller sea lion" content: found that female attendance and time spent with their pup was shaped by increasing nutritional demands of the pup and the pups suckling efficiency. Females average having 21 hours ashore and 36 hours at sea. As the pups aged, females began to spend more time at sea again. As the pups mature, specifically at the sixth week past parturition, the mother's sea time declines by 30 percent. There is no relationship between the pups activity, or physical excursion to their suckling time, age, or sex. Their suckling time, and age and gender are unrelated to their use of energy. Labeled

title: "Steller sea lion" content: water studies showed that milk intake of the pup's had a direct relationship to their size. Pups that consumed more milk were heavier than those that didn't. These findings show that the amount of time females spend onshore with their pups is based on their pup's suckling efficiency and nutritional demands, their metabolic needs. In the past, the low pup production has been tied to an increase in nutritional stress found in females. This was believed to have contributed to the decline in Steller sea lions common to Alaska. In order to be able to dive for a long period

title: "Steller sea lion" content: of time, Steller sea lions exhibit apnea, bradycardia, and peripheral vasoconstriction. This allows them to maximize their oxygen stores and efficiently forage during their dives. In addition to those adaptations, their thick blubber layer and outer fur layer keep their body insulated during dives. Trained Steller sea lions from Vancouver Aquarium were placed in the open ocean research station at the University of British Columbia's Open Water Research Station to study their diving metabolism and behavior. Steller sea lions' dives are more energetically costly if they perform dive bouts. The aerobic diving limit (ADL) of Steller sea lion was observed

title: "Steller sea lion" content: to be affected by their nutritional state and feeding. Like most otariids, Steller sea lions are vocal in air. Mature male sea lions have a range of vocalizations as part of their territorial behaviors, including belches, growls, snorts, and hisses that serve as warnings to others. Both males and females also produce underwater noises similar to their above water sounds, described as clicks, barks, and belches. The primary function of their vocalizations is for social behavior. Sonogram readings reported that Steller Sea Lions make discrete, low frequency pulses underwater that resemble the male "belching" territorial noise made in air. These

title: "Steller sea lion" content: underwater vocalizations have an average of 20-30 pulses per second. Vocalizations are critical to mother-pup pairs, as the mothers must find their pups in a crowded breeding area when they return from foraging. The mother and pup both use distinctive calls, like names, to help differentiate themselves among the crowd of other sea lions. Their aerial vocalizations have been described as similar to the bleats of sheep, and bellows. Because Steller sea lions are sexually dimorphic in size, their hearing differs in sensitivity, possibly due to differences in size of the hearing structures. Females have a higher sensitivity than males,

title: "Steller sea lion" content: perhaps to hear the higher frequency calls of their pups. The Steller sea lion's hearing range also suggests that they are capable of hearing the underwater calls of one of their main predators, the killer whale. Steller sea lion were hunted for meat and other commodities by prehistoric communities everywhere their range intersected with human communities. Aside from food and clothing, their skin was used to cover baidarkas and kayaks. A subsistence harvest on the order of 300 animals or less continues to this day in some native communities in Alaska. Historically, the sea lion has had only very slight

title: "Steller sea lion" content: commercial value. For example, in the 19th century their whiskers sold for a penny apiece for use as tobacco-pipe cleaners. Steller sea lions are sometimes killed intentionally by fishermen, as they are seen as competitors and a threat to fish stocks. Killing sea lions is strictly prohibited in the U.S.A. and Russia, but in Japan a fixed number are still removed annually, ostensibly to protect their fisheries. In Canada, commercial hunting is prohibited, but limited hunting permits are occasionally granted if local culling is required—for example, nuisance animals destroying fish farms. In recent years, Steller sea lions have been known

title: "Steller sea lion" content: to enter the Columbia River estuary and feed on white sturgeon, several salmon species, and rainbow trout, some of which are also listed under the U.S. Endangered Species Act. They enter the Columbia River primarily in the late winter and spring, occasionally going as far upstream as Bonneville Dam. Though not as abundant as the California sea lion, they are still a concern for those agencies charged with managing the fish populations. Since the Steller sea lions are themselves protected under the Marine Mammal Protection Act, managers are compelled to use nonlethal deterrence methods, such as rubber bullets and noisemakers.

title: "Steller sea lion" content: Deterrence by the public is strictly forbidden. While the populations of the eastern and Asian stocks appear stable, the population of the western stock, particularly along the Aleutian Islands, was estimated to have fallen by 70–80% since the 1970s. As a consequence, in 1997 the western stock of Steller sea lions was listed as endangered and the eastern stock was listed as threatened under the United States Endangered Species Act. They have since been the object of intense study and the focus of much political and scientific debate in Alaska. One suspected cause of their precipitous decline was overfishing of

title: "Steller sea lion" content: Alaska pollock, herring, and other fish stocks in the Gulf of Alaska. This stems largely from the “junk-food hypothesis” representing a shift in their diet from fatty herring and capelin to leaner fare such as pollock and flounder, thereby limiting their ability to consume and store fat. Other hypotheses include increased predation by orcas and sharks, indirect effects of prey species composition shifts due to changes in climate, effects of disease or contaminants, shooting by fishermen, and others. The decline is certainly due to a complex of interrelated factors which have yet to be defined by the research effort. Another

title: "Steller sea lion" content: possible reason for decline in this species has been tied to the Nutritional Stress Hypothesis. The lack of prey corresponds to the decrease in population. In females specifically, obtaining an insufficient amount of nutrients has resulted in the failure to complete their pregnancies to full term. In October 2013, the eastern Steller sea lion was taken off the U.S. Endangered Species List after a major population comeback over the past several years.
