Kon-Tiki expedition. The "Kon-Tiki" expedition was a 1947 journey by raft across the Pacific Ocean from South America to the Polynesian islands, led by Norwegian explorer and writer Thor Heyerdahl. The raft was named "Kon-Tiki" after the Inca god Viracocha, for whom "Kon-Tiki" was said to be an old name. "" is also the name of Heyerdahl's book, the Academy Award–winning 1950 documentary film chronicling his adventures, and the 2012 dramatized feature film nominated for the Academy Award for Best Foreign Language Film.Heyerdahl believed that people from South America could have reached Polynesia during pre-Columbian times. His aim in mounting the "Kon-Tiki.

Kon-Tiki expedition. expedition was to show, by using only the materials and technologies available to those people at the time, that there were no technical reasons to prevent them from having done so. Although the expedition carried some modern equipment, such as a radio, watches, charts, sextant, and metal knives, Heyerdahl argued they were incidental to the purpose of proving that the raft itself could make the journey. This idea has recently received support from statistical analysis of genetic evidence of contact between South America and Polynesia.Heyerdahl's full hypothesis of a South American origin of the Polynesian peoples is generally rejected by.

Kon-Tiki expedition. scientists today. Most archaeological, linguistic, cultural, and genetic evidence tends to support a western origin for Polynesians, from Island Southeast Asia, using sophisticated multihull sailing technologies and navigation techniques during the Austronesian expansion. However, there is evidence of some gene flow from South America to Easter Island. In 2020 some researchers published research confirming a wider impact on genetic and cultural elements in Polynesia due to South American contacts. The "Kon-Tiki" expedition was funded by private loans, along with donations of equipment from the United States Army. Heyerdahl and a small team went to Peru, where, with the help of.

Kon-Tiki expedition. dockyard facilities provided by the Peruvian authorities, they constructed the raft out of balsa logs and other native materials in an indigenous style as recorded in illustrations by Spanish conquistadores. The trip began on April 28, 1947. Heyerdahl and five companions sailed the raft for 101 days over 6,900 km (4,300 miles) across the Pacific Ocean before smashing into a reef at Raroia in the Tuamotus on August 7, 1947. The crew made successful landfall and all returned safely.Thor Heyerdahl's book about his experience became a bestseller. It was published in Norwegian in 1948 as "The Kon-Tiki Expedition: By Raft.

Kon-Tiki expedition. Across the South Seas", later reprinted as "Kon-Tiki: Across the Pacific in a Raft". It appeared with great success in English in 1950, also in many other languages. A documentary motion picture about the expedition, also called "Kon-Tiki", was produced from a write-up and expansion of the crew's filmstrip notes and won an Academy Award in 1951. It was directed by Heyerdahl and edited by Olle Nordemar. The voyage was also chronicled in the documentary TV-series "The Kon-Tiki Man: The Life and Adventures of Thor Heyerdahl", directed by Bengt Jonson.The original "Kon-Tiki" raft is now on display in the Kon-Tiki.

Kon-Tiki expedition. Museum at Bygdøy in Oslo.## Crew."Kon-Tiki" had a six-man crew, all of whom were Norwegian except for Bengt Danielsson, a Swede. Thor Heyerdahl (1914–2002) was the expedition leader. He was also the author of the book of the expedition and the narrator of the story. Heyerdahl had studied the ancient people of South America and Polynesia and believed that there was a link between the two. Erik Hesselberg (1914–1972) was the navigator and artist. He painted the large Kon-Tiki figure on the raft's sail. His children's book "Kon-Tiki and I" appeared in Norwegian in 1949 and has since been published.

Kon-Tiki expedition. in more than 15 languages. Bengt Danielsson (1921–1997) took on the role of steward, in charge of supplies and daily rations. Danielsson was a Swedish sociologist interested in human migration theory. He also served as translator, as he was the only member of the crew who spoke Spanish. He was also a voracious reader; his box aboard the raft contained many books. Knut Haugland (1917–2009) was a radio expert, decorated by the British in World War II for actions in the Norwegian heavy water sabotage that stalled what were believed to be Germany's plans to develop an atomic bomb. Haugland.

Kon-Tiki expedition. was the last surviving crew member; he died on Christmas Day, 2009 at the age of 92. Torstein Raaby (1918–1964) was also in charge of radio transmissions. He gained radio experience while hiding behind German lines during WWII, spying on the German battleship "Tirpitz". His secret radio transmissions eventually helped guide in Allied bombers to sink the ship. Herman Watzinger (1910–1986) was an engineer whose area of expertise was in technical measurements. He was the first to join Heyerdahl for the trip. He collected and recorded all sorts of data on the voyage. Much of what he recorded, such as.

Kon-Tiki expedition. weather data, was sent back to various people, since this area of the ocean was largely unstudied.The expedition also carried a pet parrot named Lorita.## Construction.The main body of the float was composed of nine balsa tree trunks up to 45 (ft) long, 2 (ft) in diameter, lashed together with 1+1/4 (in) hemp ropes. Cross-pieces of balsa logs 18 (ft) long and 1 (ft) in diameter were lashed across the logs at 3 (ft) intervals to give lateral support. Pine splashboards clad the bow, and lengths of pine 1 (in) thick and 2 (ft) wide were wedged between the balsa.

Kon-Tiki expedition. logs and used as centreboards.The main mast was made of lengths of mangrove wood lashed together to form an A-frame 29 (ft) high. Behind the main-mast was a cabin of plaited bamboo 14 (ft) long and 8 (ft) wide, about 4 - 5 (ft) high and roofed with banana leaf thatch. At the stern was a 19 (ft) long steering oar of mangrove wood, with a blade of fir. The main sail was 15 by 18 (ft) on a yard of bamboo stems lashed together. Photographs also show a top-sail above the main sail, and also a mizzen-sail, mounted at.

Kon-Tiki expedition. the stern.The raft was partially decked in split bamboo. The main spars were a laminate of wood and reeds and Heyerdahl tested more than twenty different composites before settling on one that proved an effective compromise between bulk and torsional rigidity. No metal was used in the construction.## Supplies."Kon-Tiki" carried 275 (USgal) of drinking water in 56 water cans, as well as a number of sealed bamboo rods. The purpose stated by Heyerdahl for carrying modern and ancient containers was to test the effectiveness of ancient water storage. For food "Kon-Tiki" carried 200 coconuts, sweet potatoes, bottle gourds and other.

Kon-Tiki expedition. assorted fruit and roots. The U.S. Army Quartermaster Corps provided field rations, tinned food and survival equipment. In return, the "Kon-Tiki" explorers reported on the quality and utility of the provisions. They also caught plentiful numbers of fish, particularly flying fish, "dolphin fish", yellowfin tuna, bonito and shark.Heyerdahl and crew were equipped with water-tight sports wristwatches manufactured by Swiss watchmaking firm Eterna. After the journey, Eterna decided to brand their sports watches as "Kon-Tiki".## Communications.The expedition carried an amateur radio station with the call sign of LI2B operated by former World War II Norwegian resistance radio operators Knut Haugland and.

Kon-Tiki expedition. Torstein Raaby. Haugland and Raaby maintained regular communication with a number of American, Canadian, and South American stations that relayed "Kon Tiki's" status to the Norwegian Embassy in Washington, D.C. On August 5, Haugland made contact with a station in Oslo, Norway, 10000 (mi) away."Kon Tiki's" transmitters were powered by batteries and a hand-cranked generator and operated on the 40, 20, 10, and 6-meter bands. Each unit was water resistant, used 2E30 vacuum tubes, and provided approximately 6 watts of RF output; the equivalent of a small flashlight. Two British 3-16 MHz Mark II transmitters were also carried on board,.

Kon-Tiki expedition. as was a VHF transmitter for communicating with aircraft and a hand-cranked survival radio of the Gibson Girl type for 500 and 8280 kHz.The radio receiver used throughout the voyage, a National Radio Company NC-173, once required a thorough drying out after being soaked when landing in Raratonga. The crew once used a hand-cranked emergency transmitter to send out an "all well, all well" message "just in time to head off a massive rescue attempt".The call sign LI2B was used by Heyerdahl again in 1969–70, when he built a papyrus reed raft and sailed from Morocco to Barbados in an.

Kon-Tiki expedition. attempt to show a possible link between the civilization of ancient Egypt and the New World.## The voyage."Kon-Tiki" left Callao, Peru, on the afternoon of April 28, 1947. To avoid coastal traffic it was initially towed 50 (mi) out by the Peruvian Navy fleet tug "Guardian Rios", then sailed roughly west carried along on the Humboldt Current.On 2 July Heyerdahl writes about an encounter with a rogue wave; in his book he describes a "Three Sister" phenomenon: "During a night-shift with quiet seas appears an 'abnormal huge wave' followed by two more waves. The raft is being swept up and.

Kon-Tiki expedition. down and is covered in water." After the three waves he describes the sea as quiet as before.The crew's first sight of land was the atoll of Puka-Puka on July 30. On August 4, the 97th day after departure, "Kon-Tiki" reached the Angatau atoll. The crew made brief contact with the inhabitants of Angatau Island, but were unable to land safely. Calculations made by Heyerdahl before the trip had indicated that 97 days was the minimum amount of time required to reach the Tuamotus, so the encounter with Angatau showed that they had made good time.On August 7, the voyage.

Kon-Tiki expedition. ended when the raft struck a reef and was then beached on an uninhabited islet off Raroia atoll in the Tuamotus. The team had travelled a distance of around 6980 (km) in 101 days, at an average speed of 1.5 (kn).After spending a number of days alone on the islet, the crew was greeted by men from a village on a nearby island who arrived in canoes, having seen washed-up flotsam from the raft. The crew were taken back to the native village, where they were feted with traditional dances and other festivities. Finally the crew were taken off Raroia.

Kon-Tiki expedition. to Tahiti by the French schooner "Tamara", with the salvaged "Kon-Tiki" in tow.## Anthropology.The basis of the "Kon-Tiki" expedition was pseudoscientific, racially controversial, and has not gained acceptance among scientists (even prior to the voyage). Heyerdahl believed that the original inhabitants of Easter Island (and the rest of Polynesia) were the "Tiki people", a race of "white bearded men" who supposedly originally sailed from Peru. He described these "Tiki people" as being a sun-worshipping fair-skinned people with blue eyes, fair or red hair, tall statures, and beards. He further said that these people were originally from the Middle East, and.

Kon-Tiki expedition. had crossed the Atlantic earlier to found the great Mesoamerican civilizations. By 500 CE, a branch of these people were supposedly forced out into Tiahuanaco where they became the ruling class of the Inca Empire and set out to voyage into the Pacific Ocean under the leadership of "Con Ticci Viracocha".He argued that the monumental statues known as moai resembled sculptures more typical of pre-Columbian Peru than any Polynesian designs. He believed that the Easter Island myth of a power struggle between two peoples called the Hanau epe and Hanau momoko was a memory of conflicts between the original inhabitants.

Kon-Tiki expedition. of the island and a later wave of Native Americans from the Northwest coast, eventually leading to the annihilation of the Hanau epe and the destruction of the island's culture and once-prosperous economy. Heyerdahl described these later migrants as "Maori-Polynesians" who were supposedly Asians who crossed over the Bering land bridge into Northwest America before sailing westward towards Polynesia (the westward direction is because he refused to accept that Polynesians were capable of sailing against winds and currents). He associated them with the Tlingit and Haida peoples and characterized them as "inferior" to the Tiki people.Heyerdahl's hypothesis was part of.

Kon-Tiki expedition. early Eurocentric hyperdiffusionism and the westerner disbelief that (non-white) "stone-age" peoples with "no math" could colonize islands separated by vast distances of ocean water, even against prevailing winds and currents. He rejected the highly skilled voyaging and navigating traditions of the Austronesian peoples and instead argued that Polynesia was settled from boats following the wind and currents for navigation from South America. As such, the "Kon-Tiki" was deliberately a primitive raft and unsteerable, in contrast to the sophisticated outrigger canoes and catamarans of the Austronesian people.Heyerdahl's hypothesis of Polynesian origins is overwhelmingly rejected by scientists today. Archaeological, linguistic, cultural, and.

Kon-Tiki expedition. genetic evidence all support a western origin (from Island Southeast Asia) for Polynesians via the Austronesian expansion. "Drift voyaging" from South America was also deemed "extremely unlikely" in 1973 by computer modeling, although is in contrast with recent genetic analysis. The 1976 voyage of the "Hōkūleʻa", a performance-accurate replica of a Polynesian double-hulled "wa'a kaulua" voyaging canoe, from Hawaiʻi to Tahiti was partly a demonstration to prove that Heyerdahl was wrong. The "Hōkūleʻa" sailed against prevailing winds and exclusively used wayfinding and celestial Polynesian navigation techniques (unlike the modern equipment and charts of the "Kon-Tiki"). "Hōkūleʻa" also remains fully operational,.

Kon-Tiki expedition. and has since completed ten other voyages, including a three-year circumnavigation of the planet from 2014 to 2017, with other sister ships.Historians today consider that the Polynesians from the west were the original inhabitants and that the story of the Hanau epe is either pure myth, or a memory of internal tribal or class conflicts. In 2011, Erik Thorsby of the University of Oslo presented DNA evidence to the Royal Society which, whilst agreeing with the west origin, also identified a distinctive but smaller genetic contribution from South America. This result was questioned in 2012 because of the possibility of.

Kon-Tiki expedition. contamination by South Americans after European contact with the islands. In 2014, further work by a team including Anna-Sapfo Malaspinas (from the Natural History Museum of Denmark) analysed the genomes of 27 native Rapa Nui people and found that their DNA was on average 76 percent Polynesian, 8 percent Native American and 16 percent European. Analysis showed that "although the European lineage could be explained by contact with white Europeans after the island was 'discovered' in 1722 by Dutch sailors, the South American component was much older, dating to between about 1280 and 1495, soon after the island was first.

Kon-Tiki expedition. colonised by Polynesians in around 1200." Genetic analysis of Polynesians and Native South Americans, published in "Nature" in July 2020, has revealed that several eastern Polynesian populations have signs of an ancient genetic signature that originated from Native South American people. An initial admixture event between Native South Americans and Polynesians, discovered by statistical analysis, took place around 1150–1230 CE.## Later recreations of "Kon-Tiki".## "Seven Little Sisters".In 1954, William Willis sailed alone on a raft "Seven Little Sisters" from Peru to American Samoa, successfully completing the journey. He sailed 6,700 (mi), which was 2,200 (mi) farther than "Kon-Tiki". In a.

Kon-Tiki expedition. second great voyage ten years later, he rafted 7457 (mi) from South America to Australia with a metal raft "Age Unlimited".## "Kantuta".In 1955, the Czech explorer and adventurer Eduard Ingris attempted to recreate the "Kon-Tiki" expedition on a balsa raft called "Kantuta". His first expedition, "Kantuta I", took place in 1955–1956 and led to failure. In 1959, Ingris built a new balsa raft, "Kantuta II", and tried to repeat the previous expedition. The second expedition was a success. Ingris was able to cross the Pacific Ocean on the balsa raft from Peru to Polynesia.## "Tahiti-Nui".A French seafarer, Éric de Bisschop,.

Kon-Tiki expedition. committed himself in a project he had had for some years: he built a Polynesian raft in order to cross the eastern Pacific Ocean from Tahiti to Chile (contrary to Thor Heyerdahl's crossing); the "Tahiti-Nui" left Papeete with a crew of five on November 8, 1956. When near the Juan Fernández Islands (Chile) in May 1957, the raft was in a very poor state and they asked for a towing, but it was damaged during the operation and had to be abandoned, but they were able to preserve all the equipment that had been aboard.## "Tahiti-Nui II".A second "Tahiti-Nui" was.

Kon-Tiki expedition. built in Constitución, Chile, leaving on April 13, 1958, towards Callao, then towards the Marquesas. It missed its target and after four months, the raft began to sink. The crew built a new smaller raft, the "Tahiti Nui III", in the ocean out of the more buoyant parts of the "Tahiti Nui II". They were swept towards Cook Islands where on August 30, the raft went aground and was wrecked at Rakahanga atoll. Éric de Bisschop died in this accident.## "Tangaroa" (1965).A Peruvian expedition led by Carlos Caravedo crossed the Pacific Ocean in 1965 in 115 days in a raft.

Kon-Tiki expedition. named "Tangaroa", of which 18 days were used by the crew to cross Tuamotus, the Tuamotu Archipielago, making "Tangaroa" the only raft that has managed to cross that dangerous archipelago of French Polynesia by its own means. On November 18, 1965, the "Tangaroa" ended its journey on the Fakarava island. Fakarava is where the "Tangaroa" is currently preserved.## Las Balsas.The 1973 Las Balsas expedition was the first (and so far only) multiple-raft crossing of the Pacific Ocean in recent history. It is the longest-known raft voyage in history. The expedition was led by Spaniard Vital Alsar, who, in 1970, led.

Kon-Tiki expedition. the La Balsa expedition, only on that occasion with one raft and three companions. The crossing was successful and, at the time, the longest raft voyage in history, until eclipsed in 1973 by Las Balsas. The purpose of the 1973 expedition was three-fold: (1) to prove that the success of 1970 was no accident, (2) to test different currents in the sea, which Alsar maintained ancient mariners knew as modern humans know road maps, and (3) to show that the original expeditions, directed perhaps toward trade or colonisation, may have consisted of small fleets of balsa rafts.## "Tangaroa" (2006).In 2006,.

Kon-Tiki expedition. the Tangaroa Expedition recreated the "Kon-Tiki" voyage using a newly built raft, the "Tangaroa", named after the Māori sea-god Tangaroa. Tangaroa's six-man crew was led by Norwegian Torgeir Higraff and included Olav Heyerdahl, grandson of Thor Heyerdahl, Bjarne Krekvik (captain), Øyvin Lauten (executive officer), Swedish Anders Berg (photographer) and Peruvian Roberto Sala. "Tangaroa" was launched on the same day that "Kon-Tiki" had been—April 28—and it reached its destination on July 7, which was 30 days faster than Heyerdahl's Kon-Tiki which had taken 101 days for the voyage. Tangaroa's speed was credited to the proper use of guaras (centerboards).## "An-Tiki".On January.

Kon-Tiki expedition. 30, 2011, "An-Tiki", a raft modeled after "Kon-Tiki", began a 3000 (mi), 70-day journey across the Atlantic Ocean from the Canary Islands to the island of Eleuthera in the Bahamas. The expedition was piloted by four men, aged from 56 to 84 years, led by Anthony Smith. The trip was designed to commemorate the journey in an open boat of survivors from the British steamship "Anglo-Saxon", sunk by the German cruiser "Widder" in 1940. The raft ended its voyage in the Caribbean island of St Maarten, completing its trip to Eleuthera in the following year with Smith and a new.

Kon-Tiki expedition. crew.## "Kon-Tiki2".On 7 November 2015, two teams with two balsa rafts "Rahiti Tane" and "Tupac Yupanqui" left Lima, Peru for Easter Island. Expedition "Kon-Tiki2" got its name because it had 2 crews from many nations: Norway, Russia, UK, Mexico, New Zealand, Sweden, and Peru. It sought to double down on Heyerdahl's voyage by sailing two rafts from South America to Polynesia and then back. Expedition leader was Torgeir Higraff from Tangaroa Expedition (2006). Øyvin Lauten and Kari Skår Dahl were captains on the first leg, while Signe Meling and Ola Borgfjord were captains on the second leg. The raft reached.

Kon-Tiki expedition. Easter Island, but did not complete the return.The two rafts were made of 11 balsa logs and 10 crossbeams held together by 2000 meters (1¼ miles) of natural fiber ropes. Tens of thousands of waves, up to six meters (20') tall, hit the rafts in an El Niño year. This stress for 16 weeks weakened the ropes, but the crew could not replace all of them. On March 3, 2016, all crew members were taken on board the Hokuetsu Ushaka freight ship after 115 days of sailing and 4½ months at sea.## Documentation.## Memoir book.A book documenting the voyage and.

Adventfjorden. Adventfjorden (Advent Bay) is a 7 km long and 4 km wide bay running south-eastwards from the southern side of Isfjorden, on the west coast of Spitsbergen in Svalbard. The name represents a corruption of "Adventure Bay" - probably named after the Hull-built whaleship "Adventure", which operated in Isfjorden in 1656. The fjord was originally known as "Klass Billen Bay". At the head of Adventfjorden is Adventdalen (Advent Valley).The former mining-camp of Longyearbyen (now Svalbard's main town) lies on the fjord's southwestern shore, while another former mining-camp, Hiorthhamn, is located on its northeastern shore.Conway, W.

Coprinopsis lagopus. Coprinopsis lagopus is a species of fungus in the family Psathyrellaceae. Until 2001, the species was known as "Coprinus lagopus"; advances in the understanding of phylogenetic relationships between the various coprinoid species led to a major reorganization of that genus. It is a delicate and short-lived fungus, the fruit bodies lasting only a few hours before dissolving into a black ink – a process called "deliquescence". The vague resemblance of the young fruit body to the paw of a white rabbit has earned this species the common name harefoot mushroom.## Description.The fruit body size of "Coprinopsis lagopus" can vary tremendously.

Coprinopsis lagopus. very dark-brown at center beneath the whitish to silvery grey veil but becomes paler towards the margin. As the mushroom matures, the shape of the cap becomes more conical or convex, and finally flattens out, with edges curved upward. The veil is initially whitish, then turns to a silvery grey or grey-brown; it eventually splits up, becoming hairy (fibrillose). The gills are freely attached to the stem, very thin and crowded closely together. Initially, the color of the gills is white, then progresses to grayish-brown then to black as the spores mature. In maturity the gill edges dissolve ("deliquesce") into.

Coprinopsis lagopus. a black liquid. These mushrooms are evanescent, lasting only a few hours before dying; the autodigestive process is enhanced in humid environments. The stem is whitish in color, and is hollow, hairy (flocculose) over the whole surface but especially at lower parts, and becomes smooth (glabrous) with age. The spore print is violet-black.The species is nonpoisonous. Its edibility is unknown but it is considered too small to be worthwhile.## Microscopic features.Spores have dimensions of 11–13 x 6–8 μm. They are ellipsoid or ovoid in shape, with a rounded base and apex, dark red-brown in color, and nonamyloid.The cystidia found on.

As no electricity distribution system was available at the time, no practical commercial market emerged for these motors.After many other more or less successful attempts with relatively weak rotating and reciprocating apparatus Prussian/Russian Moritz von Jacobi created the first real rotating electric motor in May 1834. It developed remarkable mechanical output power. His motor set a world record, which Jacobi improved four years later in September 1838.

Calystegia sepium. Calystegia sepium (hedge bindweed, Rutland beauty, bugle vine, heavenly trumpets, bellbind, granny-pop-out-of-bed and many others) is a species of flowering plant in the family Convolvulaceae. It has a subcosmopolitan distribution throughout temperate regions of the North and South hemispheres.## Description.It is an herbaceous perennial that twines around other plants, in a counter-clockwise direction, to a height of up to 2 - 4 (m), rarely 5 (m). The pale matte green leaves are arranged spirally, simple, pointed at the tip and are arrowhead shaped, 5–10 (cm) long and 3–7 (cm) broad.The flowers are white, or pale pink with five darker stripes,.

Calystegia sepium. in hedges, fields, borders, roadsides and open woods.Hedge bindweed is toxic, containing calystegine alkaloids.## Identification.There are several species of "Calystegia" which and occur in similar habitats and can be difficult to distinguish, especially when not in flower. It is common practice in Britain to treat "C. sepium", "C. silvatica" and "C. pulchra" as an aggregate, usually recorded as ""C. sepium" agg.", whenever identification is uncertain. The use of this term sometimes creates confusion about which taxon is being discussed.The best way to separate hedge bindweed ("sepium") from the other taxa is by the bracteoles, which subtend the flower and wholly.

Shaft sinking. Shaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.Shaft sinking is one of the most difficult of all mine development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Shafts may be sunk by conventional drill and blast or mechanised means.Historically, mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve.

Shaft sinking. of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada, Germany, China and South Africa.The modern shaft sinking industry is gradually shifting further towards greater mechanisation, recent innovations in the form of full-face shaft boring (akin to a vertical tunnel boring machine) have shown promise but the use of this method is, as of 2019, not widespread.## Mine shafts.Mine shafts are vertical or near-vertical tunnels, which are "sunk" as a means of accessing an underground ore body, during of the development of an underground mine.The shape (in plan view), dimensions and depth of mine shafts vary greatly.

Shaft sinking. in response to the specific needs of the mine they are part of and the geology they are sunk through. For example, in North and South America, smaller shafts are designed to be rectangular in plan view with timber supports. Larger shafts are round in plan and are concrete lined.Mine shafts may be used for a variety of purposes, including as a means of escape in the event of an emergency underground and allowing for the movement of: People Materials Mine services (such as compressed air, water, backfill, power, communications and fuel) Ventilation air Broken rock (in the form of.

Shaft sinking. payable ore, or non payable waste) Or any combination of the aboveWhen the top of the excavation is the ground surface, it is referred to as a "shaft"; when the top of the excavation is underground, it is called a "winze" or a "sub-shaft". Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called "raises".A shaft may be either vertical or inclined (between 80 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of.

Shaft sinking. the proposed shaft, and ground conditions allow, then raise boring may be used to excavate the shaft from the bottom up; such shafts are called "borehole shafts".Following the Hartley Colliery disaster where the single shaft at the mine became blocked, the United Kingdom made single shaft mines illegal in 1862, establishing the practice that all underground mines must have a "a second means of egress". Many other global mining jurisdictions have adopted this rule and shafts are therefore often found in pairs (although there are multiple alternative methods of providing a second means of egress).The current the deepest single lift.

(i.e. continuous) mine shaft in the world is the 2991m deep, main shaft at South Deep Mine in South Africa, owned by Gold Fields Limited, which, along with its twin ventilation shafts, took ten years to sink and equip.## Parts of a mine shaft.The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist (or winder) used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground).

Shaft sinking. The headframe will also typically contain bins for storing ore being transferred to the processing facility.At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for workers, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out.

Shaft sinking. of the mine.Beneath the collar the part of the shaft which continues into the ground is called the "shaft barrel".At locations where the shaft barrel meets horizontal workings there is a "shaft station" (or inset) which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest shaft station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a "loading pocket" is excavated on one side of the shaft at this.

Shaft sinking. location to allow transfer facilities to be built.Beneath the lowest shaft station the shaft continues on for some distance, this area is referred to as the "shaft bottom". A tunnel called a "ramp" typically connects the bottom of the shaft with the rest of the mine, this ramp often contains the mine's water handling facility, called the "sump", as water will naturally flow to the lowest point in the mine.## Shaft lining.Many (although not all) shafts are lined following excavation and the installation of temporary ground support.The shaft lining performs several functions; it is first and foremost a safety feature.

Shaft sinking. preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into, and lastly a smooth surface to minimise resistance to airflow for ventilation.Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind "shaft forms" in.

Shaft sinking. lifts of 6 m as the shaft advances (gets deeper).Shotcrete, fibrecrete, brick, cast iron tubing, and precast concrete segments have all been used at one time or another. Additionally, the use of materials like bitumen and even squash balls have been required by specific circumstances. In extreme cases, particularly when sinking through halite, composite liners consisting of two or more materials may be required.The shaft liner does not reach right to the bottom of the shaft during sinking, but lags behind by a fixed distance. This distance is determined by the methodology of excavation and the design thickness of the.

Shaft sinking. permanent liner. To ensure the safety of persons working on the shaft bottom temporary ground support is installed, usually consisting of welded mesh and rock bolts. The installation of the temporary ground support (called "bolting") is among the most physically challenging parts of the shaft sinking cycle as bolts must be installed using pneumatic powered rock drills.For this reason, and to minimise the number of persons on the shaft bottom a number of projects have successfully switched to shotcrete for this temporary lining. Research and development in this area is focusing on the robotic application of shotcrete and the commercialisation.

Shaft sinking. of thin sprayed polymer liners.## Shaft compartments.Where the shaft is to be used for hoisting it is frequently split into multiple compartments by "shaft sets", these may be made of either timber or steel. Vertical members in a shaft set are called "guides", horizontal members are called "buntons". For steel shaft guides, the main two options are hollow structural sections and top hat sections. Top hat sections offer a number of advantages over hollow structural sections including simpler installation, improved corrosion resistance and increased stiffness. Mine conveyances run on the guides in a similar way to how a steel roller.

Shaft sinking. coaster runs on its rails, both having wheels which keep them securely in place.Some shafts do not use guide beams but instead utilize steel wire rope (called "guide rope") kept in tension by massive weights at shaft bottom called "cheese weights" (because of their resemblance to a truckle or wheel of cheese) as these are easier to maintain and replace.The largest compartment is typically used for the "mine cage", a conveyance used for moving workers and supplies below the surface, which is suspended from the hoist on steel wire rope. It functions in a similar manner to an elevator. Cages.

Shaft sinking. may be single-, double-, or rarely triple-deck, always having multiple redundant safety systems in case of unexpected failure.The second compartment is used for one or more skips, used to hoist ore to the surface. Smaller mining operations use a skip mounted underneath the cage, rather than a separate device, while some large mines have separate shafts for the cage and skips. The third compartment is used for an emergency exit; it may house an auxiliary cage or a system of ladders. An additional compartment houses mine services such as high voltage cables and pipes for transfer of water, compressed air.

Shaft sinking. or diesel fuel.A second reason to divide the shaft is for ventilation. One or more of the compartments discussed above may be used for air intake, while others may be used for exhaust. Where this is the case a steel or concrete wall called a "brattice" is installed between the two compartments to separate the air flow. At many mines there are one or more complete additional separate "auxiliary shafts" with separate head gear and cages.## Shaft construction.The lowest point in a sinking shaft is known as "shaft bottom", shaft projects differ from some other forms of mine development in.

Shaft sinking. that all activities that take place on shaft bottom become part of the critical path for the project schedule. The infrastructure required to sink a shaft is referred to a "the sinking set-up".It is typical for progress (the "sinking rate") in the sinking phase (that is excavation, ground support and lining) of a shaft project to follow a learning curve as the project team repeat the same series of activities over and over in what is called "the sinking cycle", eventually approaching the theoretical maximum rate for that sinking set up over time. The use of experienced shaft sinkers is.

Shaft sinking. necessary to reduce the length of this learning curve and thus the duration of the project as much as possible.Key to a successful shaft sinking project are: Getting the various components of the sinking set-up correct and installed at the right time. Having experienced people involved from as early in the project as possible Using the available time on shaft bottom as efficiently as possible.Although significant emphasis is placed on the rate of progress of a project sinking cycle by shaft sinkers, sinking is only one of a number of phases in the conventional construction of a new shaft, as.

Shaft sinking. follows; "Box Cut Excavation". A box cut is a large square or rectangular excavation typically completed using earthmoving equipment down to bedrock, inside which the shaft collar will be constructed. Having the loads imposed by the collar, headframe and hoisting plant transferred into solid rock is necessary to prevent unplanned subsidence. Where the depth of bedrock is to great to for a box cut to economically viable, or the bedrock is not strong enough, civil engineering techniques such as diaphragm walls or concrete piles may be used to create a deep foundation instead. "Pre-Sink". The pre-sink is the excavation and.

Shaft sinking. support of the first 60 – 100 meters of the shaft barrel, often completed smaller equipment such as handheld, pneumatic drilling equipment to drill holes for basting and ground support and mini-excavators for mucking. During the pre-sink hoisting of muck and equipment is usually performed by a mobile crane on surface. It is necessary to sink this part of the shaft first so that the Galloway, a multi-level working platform may be installed with enough vertical distance to shaft bottom that it will not be damaged by fly rock during blasting. "Collar Construction". From the bottom of the box-cut, the.

Shaft sinking. shaft collar is constructed bottom up in a planned series of concrete pours. "Galloway (Sinking Stage) Construction & Installation." The Galloway (also known as a Sinking Stage or Scaffold) is a multi-level working platform, suspended in the shaft from winches located on surface. The Galloway allows sinkers to efficiently work on differing levels as required by the various tasks of the sinking cycle. It is typical for the Galloway to be constructed off to one side of the shaft and lowered into the pre-sink with a crane in as complete a state as possible. Once in place the Galloway is.

Shaft sinking. "chaired" (suspended from the shaft collar) while the headframe is built above, often protected by a bulkhead. "Headframe & Hoist House Construction." With the collar constructed and the Galloway installed the headframe and hoist (or winder) houses may be constructed and the hoist and winch ropes installed. Headframes may be either steel or concrete and their design will determine how they are constructed. The Galloway is moved in the shaft by means of winches, which move slowly and are rated for significant loads, while the sinking buckets (or kibbles) are moved in the shaft by the sinking hoist, which moves.

Shaft sinking. quickly and is rates for less load that the winches. To protect the hoist(s) and winches and the sensitive electronics which are used to control their operation they are normally installed inside of a build called a hoist (or winder) house. "Commissioning Sinking Set Up." The Sinking set-up must then be commissioned to ensure that all parts are operating as planned. "Full Sink". The activities of the sinking cycle (excavation, installation of temporary ground support, placement of the shaft lining and extending shaft services) all take place in this phase of construction. In a shaft where there are to be.

Shaft sinking. multiple working levels, shaft stations and station stubs (short lengths of horizontal tunnel leading away from the station) will be developed by the sinkers on the way down. As the equipment to excavate these stations must be small enough to fit through the openings in the Galloway, the rate of advance in developing the station stubs is typically low, compared to what can be achieved with full size mining equipment so station stubs are typically kept as short as possible. "Shaft Equipping & Headframe Changeover." Once the shaft reaches the final design depth, the shaft is stripped of any temporary.

Shaft sinking. services, the Galloway cut up or modified to suit the installation of the permanent shaft set-up, the shaft sets (if required) installed and the headframe / winders modified to allow for permanent hoisting. Any permanent conveyances will be installed at this stage. "Commissioning Permanent Set Up." The Permanent set-up must then be commissioned to ensure that all parts are operating as planned before being handed over to the new owner.As with the depth and design of shafts significant variations do exist in this sequence depending on local conditions, for example in that hard Canadian Shield rocks which dominate shaft sinking.

Shaft sinking. in Canada a deep and complex shaft collar is unnecessary as the bedrock is both strong and close to surface. This reduces the amount of time typically required to establish the shaft collar.Traditionally sinking contractors would build a temporary headframe for the sinking set up, which would then be dismantled to make way for a permanent headframe. With the growth in complexity and duration of shaft sinking projects over time it has become more common to incorporate more of the permanent shaft set-up into the sinking phase. This results in a reduced overall project duration, as for example, if the.

Shaft sinking. service piping used to sink the shaft does not need to be stripped out to make way for permanent piping.With the advancements made in raise boring technology, raise borers have been used to create a pilot hole for shaft sinking, where access exists at the bottom of the new shaft, in this case the sinking phase is dedicated to enlarging this pilot hole to full diameter (a process usually called "slashing"). This methodology can be considerably faster than full face sinking as muck (waste rock) from sinking falls down the pilot hole and is handled using existing mine infrastructure off.

Australian wood duck. The Australian wood duck, maned duck or maned goose ("Chenonetta jubata") is a dabbling duck found throughout much of Australia. It is the only living species in the genus Chenonetta. Traditionally placed in the subfamily Anatinae (dabbling ducks), it might belong to the subfamily Tadorninae (shelducks); the ringed teal may be its closest living relative.## Taxonomy.The Australian wood duck was first described by the English ornithologist John Latham in 1801 under the binomial name "Anas jubata".The flightless New Zealand species "Chenonetta finschi" (Finsch's duck) which was formerly believed to constitute a monotypic genus ("Euryanas") has been determined to belong to.

Saint Augustine's Reach became the heart of Bristol's docks with its quays and wharfs. The River Avon within the gorge, and the River Severn into which it flows, has tides which fluctuate about 30 (ft) between high and low water. This means that the river is easily navigable at high tide but reduced to a muddy channel at low tide in which ships would often run aground. Ships had no option but to be stranded in the harbour.

Wolf. habitat.Wolves occur across Eurasia and North America. However, deliberate human persecution because of livestock predation and fear of attacks on humans has reduced the wolf's range to about one-third of its historic range; the wolf is now extirpated (locally extinct) from much of its range in Western Europe, the United States and Mexico, and completely in Ireland, the United Kingdom, and Japan. In modern times, the wolf occurs mostly in wilderness and remote areas. The wolf can be found between sea level and 3000 (m). Wolves live in forests, inland wetlands, shrublands, grasslands (including Arctic tundra), pastures, deserts, and rocky.

Wolf. are nocturnal predators. During the winter, a pack will commence hunting in the twilight of early evening and will hunt all night, traveling tens of kilometres. Sometimes hunting large prey occurs during the day. During the summer, wolves generally tend to hunt individually, ambushing their prey and rarely giving pursuit.When hunting large gregarious prey, wolves will try to isolate an individual from its group. If successful, a wolf pack can bring down game that will feed it for days, but one error in judgement can lead to serious injury or death. Most large prey have developed defensive adaptations and behaviours.

Kon-Tiki expedition. The "Kon-Tiki" expedition was a 1947 journey by raft across the Pacific Ocean from South America to the Polynesian islands, led by Norwegian explorer and writer Thor Heyerdahl. The raft was named "Kon-Tiki" after the Inca god Viracocha, for whom "Kon-Tiki" was said to be an old name. "" is also the name of Heyerdahl's book, the Academy Award–winning 1950 documentary film chronicling his adventures, and the 2012 dramatized feature film nominated for the Academy Award for Best Foreign Language Film.Heyerdahl believed that people from South America could have reached Polynesia during pre-Columbian times. His aim in mounting the "Kon-Tiki.

Kon-Tiki expedition. expedition was to show, by using only the materials and technologies available to those people at the time, that there were no technical reasons to prevent them from having done so. Although the expedition carried some modern equipment, such as a radio, watches, charts, sextant, and metal knives, Heyerdahl argued they were incidental to the purpose of proving that the raft itself could make the journey. This idea has recently received support from statistical analysis of genetic evidence of contact between South America and Polynesia.Heyerdahl's full hypothesis of a South American origin of the Polynesian peoples is generally rejected by.

Kon-Tiki expedition. scientists today. Most archaeological, linguistic, cultural, and genetic evidence tends to support a western origin for Polynesians, from Island Southeast Asia, using sophisticated multihull sailing technologies and navigation techniques during the Austronesian expansion. However, there is evidence of some gene flow from South America to Easter Island. In 2020 some researchers published research confirming a wider impact on genetic and cultural elements in Polynesia due to South American contacts. The "Kon-Tiki" expedition was funded by private loans, along with donations of equipment from the United States Army. Heyerdahl and a small team went to Peru, where, with the help of.

Kon-Tiki expedition. dockyard facilities provided by the Peruvian authorities, they constructed the raft out of balsa logs and other native materials in an indigenous style as recorded in illustrations by Spanish conquistadores. The trip began on April 28, 1947. Heyerdahl and five companions sailed the raft for 101 days over 6,900 km (4,300 miles) across the Pacific Ocean before smashing into a reef at Raroia in the Tuamotus on August 7, 1947. The crew made successful landfall and all returned safely.Thor Heyerdahl's book about his experience became a bestseller. It was published in Norwegian in 1948 as "The Kon-Tiki Expedition: By Raft.

Kon-Tiki expedition. Across the South Seas", later reprinted as "Kon-Tiki: Across the Pacific in a Raft". It appeared with great success in English in 1950, also in many other languages. A documentary motion picture about the expedition, also called "Kon-Tiki", was produced from a write-up and expansion of the crew's filmstrip notes and won an Academy Award in 1951. It was directed by Heyerdahl and edited by Olle Nordemar. The voyage was also chronicled in the documentary TV-series "The Kon-Tiki Man: The Life and Adventures of Thor Heyerdahl", directed by Bengt Jonson.The original "Kon-Tiki" raft is now on display in the Kon-Tiki.

Kon-Tiki expedition. Museum at Bygdøy in Oslo.## Crew."Kon-Tiki" had a six-man crew, all of whom were Norwegian except for Bengt Danielsson, a Swede. Thor Heyerdahl (1914–2002) was the expedition leader. He was also the author of the book of the expedition and the narrator of the story. Heyerdahl had studied the ancient people of South America and Polynesia and believed that there was a link between the two. Erik Hesselberg (1914–1972) was the navigator and artist. He painted the large Kon-Tiki figure on the raft's sail. His children's book "Kon-Tiki and I" appeared in Norwegian in 1949 and has since been published.

Danielsson was a Swedish sociologist interested in human migration theory. He also served as translator, as he was the only member of the crew who spoke Spanish. He was also a voracious reader; his box aboard the raft contained many books. Knut Haugland (1917–2009) was a radio expert, decorated by the British in World War II for actions in the Norwegian heavy water sabotage that stalled what were believed to be Germany's plans to develop an atomic bomb.

He gained radio experience while hiding behind German lines during WWII, spying on the German battleship "Tirpitz". His secret radio transmissions eventually helped guide in Allied bombers to sink the ship. Herman Watzinger (1910–1986) was an engineer whose area of expertise was in technical measurements. He was the first to join Heyerdahl for the trip. He collected and recorded all sorts of data on the voyage. Much of what he recorded, such as.

On August 4, the 97th day after departure, "Kon-Tiki" reached the Angatau atoll. The crew made brief contact with the inhabitants of Angatau Island, but were unable to land safely. Calculations made by Heyerdahl before the trip had indicated that 97 days was the minimum amount of time required to reach the Tuamotus, so the encounter with Angatau showed that they had made good time.On August 7, the voyage.

The team had travelled a distance of around 6980 (km) in 101 days, at an average speed of 1.5 (kn).After spending a number of days alone on the islet, the crew was greeted by men from a village on a nearby island who arrived in canoes, having seen washed-up flotsam from the raft. The crew were taken back to the native village, where they were feted with traditional dances and other festivities. Finally the crew were taken off Raroia.

Kon-Tiki expedition. to Tahiti by the French schooner "Tamara", with the salvaged "Kon-Tiki" in tow.## Anthropology.The basis of the "Kon-Tiki" expedition was pseudoscientific, racially controversial, and has not gained acceptance among scientists (even prior to the voyage). Heyerdahl believed that the original inhabitants of Easter Island (and the rest of Polynesia) were the "Tiki people", a race of "white bearded men" who supposedly originally sailed from Peru. He described these "Tiki people" as being a sun-worshipping fair-skinned people with blue eyes, fair or red hair, tall statures, and beards. He further said that these people were originally from the Middle East, and.

Kon-Tiki expedition. had crossed the Atlantic earlier to found the great Mesoamerican civilizations. By 500 CE, a branch of these people were supposedly forced out into Tiahuanaco where they became the ruling class of the Inca Empire and set out to voyage into the Pacific Ocean under the leadership of "Con Ticci Viracocha".He argued that the monumental statues known as moai resembled sculptures more typical of pre-Columbian Peru than any Polynesian designs. He believed that the Easter Island myth of a power struggle between two peoples called the Hanau epe and Hanau momoko was a memory of conflicts between the original inhabitants.

Kon-Tiki expedition. of the island and a later wave of Native Americans from the Northwest coast, eventually leading to the annihilation of the Hanau epe and the destruction of the island's culture and once-prosperous economy. Heyerdahl described these later migrants as "Maori-Polynesians" who were supposedly Asians who crossed over the Bering land bridge into Northwest America before sailing westward towards Polynesia (the westward direction is because he refused to accept that Polynesians were capable of sailing against winds and currents). He associated them with the Tlingit and Haida peoples and characterized them as "inferior" to the Tiki people.Heyerdahl's hypothesis was part of.

Kon-Tiki expedition. early Eurocentric hyperdiffusionism and the westerner disbelief that (non-white) "stone-age" peoples with "no math" could colonize islands separated by vast distances of ocean water, even against prevailing winds and currents. He rejected the highly skilled voyaging and navigating traditions of the Austronesian peoples and instead argued that Polynesia was settled from boats following the wind and currents for navigation from South America. As such, the "Kon-Tiki" was deliberately a primitive raft and unsteerable, in contrast to the sophisticated outrigger canoes and catamarans of the Austronesian people.Heyerdahl's hypothesis of Polynesian origins is overwhelmingly rejected by scientists today. Archaeological, linguistic, cultural, and.

Kon-Tiki expedition. genetic evidence all support a western origin (from Island Southeast Asia) for Polynesians via the Austronesian expansion. "Drift voyaging" from South America was also deemed "extremely unlikely" in 1973 by computer modeling, although is in contrast with recent genetic analysis. The 1976 voyage of the "Hōkūleʻa", a performance-accurate replica of a Polynesian double-hulled "wa'a kaulua" voyaging canoe, from Hawaiʻi to Tahiti was partly a demonstration to prove that Heyerdahl was wrong. The "Hōkūleʻa" sailed against prevailing winds and exclusively used wayfinding and celestial Polynesian navigation techniques (unlike the modern equipment and charts of the "Kon-Tiki"). "Hōkūleʻa" also remains fully operational,.

Kon-Tiki expedition. and has since completed ten other voyages, including a three-year circumnavigation of the planet from 2014 to 2017, with other sister ships.Historians today consider that the Polynesians from the west were the original inhabitants and that the story of the Hanau epe is either pure myth, or a memory of internal tribal or class conflicts. In 2011, Erik Thorsby of the University of Oslo presented DNA evidence to the Royal Society which, whilst agreeing with the west origin, also identified a distinctive but smaller genetic contribution from South America. This result was questioned in 2012 because of the possibility of.

Kon-Tiki expedition. contamination by South Americans after European contact with the islands. In 2014, further work by a team including Anna-Sapfo Malaspinas (from the Natural History Museum of Denmark) analysed the genomes of 27 native Rapa Nui people and found that their DNA was on average 76 percent Polynesian, 8 percent Native American and 16 percent European. Analysis showed that "although the European lineage could be explained by contact with white Europeans after the island was 'discovered' in 1722 by Dutch sailors, the South American component was much older, dating to between about 1280 and 1495, soon after the island was first.

Kon-Tiki expedition. colonised by Polynesians in around 1200." Genetic analysis of Polynesians and Native South Americans, published in "Nature" in July 2020, has revealed that several eastern Polynesian populations have signs of an ancient genetic signature that originated from Native South American people. An initial admixture event between Native South Americans and Polynesians, discovered by statistical analysis, took place around 1150–1230 CE.## Later recreations of "Kon-Tiki".## "Seven Little Sisters".In 1954, William Willis sailed alone on a raft "Seven Little Sisters" from Peru to American Samoa, successfully completing the journey. He sailed 6,700 (mi), which was 2,200 (mi) farther than "Kon-Tiki". In a.

Kon-Tiki expedition. second great voyage ten years later, he rafted 7457 (mi) from South America to Australia with a metal raft "Age Unlimited".## "Kantuta".In 1955, the Czech explorer and adventurer Eduard Ingris attempted to recreate the "Kon-Tiki" expedition on a balsa raft called "Kantuta". His first expedition, "Kantuta I", took place in 1955–1956 and led to failure. In 1959, Ingris built a new balsa raft, "Kantuta II", and tried to repeat the previous expedition. The second expedition was a success. Ingris was able to cross the Pacific Ocean on the balsa raft from Peru to Polynesia.## "Tahiti-Nui".A French seafarer, Éric de Bisschop,.

Kon-Tiki expedition. committed himself in a project he had had for some years: he built a Polynesian raft in order to cross the eastern Pacific Ocean from Tahiti to Chile (contrary to Thor Heyerdahl's crossing); the "Tahiti-Nui" left Papeete with a crew of five on November 8, 1956. When near the Juan Fernández Islands (Chile) in May 1957, the raft was in a very poor state and they asked for a towing, but it was damaged during the operation and had to be abandoned, but they were able to preserve all the equipment that had been aboard.## "Tahiti-Nui II".A second "Tahiti-Nui" was.

Kon-Tiki expedition. built in Constitución, Chile, leaving on April 13, 1958, towards Callao, then towards the Marquesas. It missed its target and after four months, the raft began to sink. The crew built a new smaller raft, the "Tahiti Nui III", in the ocean out of the more buoyant parts of the "Tahiti Nui II". They were swept towards Cook Islands where on August 30, the raft went aground and was wrecked at Rakahanga atoll. Éric de Bisschop died in this accident.## "Tangaroa" (1965).A Peruvian expedition led by Carlos Caravedo crossed the Pacific Ocean in 1965 in 115 days in a raft.

Kon-Tiki expedition. named "Tangaroa", of which 18 days were used by the crew to cross Tuamotus, the Tuamotu Archipielago, making "Tangaroa" the only raft that has managed to cross that dangerous archipelago of French Polynesia by its own means. On November 18, 1965, the "Tangaroa" ended its journey on the Fakarava island. Fakarava is where the "Tangaroa" is currently preserved.## Las Balsas.The 1973 Las Balsas expedition was the first (and so far only) multiple-raft crossing of the Pacific Ocean in recent history. It is the longest-known raft voyage in history. The expedition was led by Spaniard Vital Alsar, who, in 1970, led.

Kon-Tiki expedition. the La Balsa expedition, only on that occasion with one raft and three companions. The crossing was successful and, at the time, the longest raft voyage in history, until eclipsed in 1973 by Las Balsas. The purpose of the 1973 expedition was three-fold: (1) to prove that the success of 1970 was no accident, (2) to test different currents in the sea, which Alsar maintained ancient mariners knew as modern humans know road maps, and (3) to show that the original expeditions, directed perhaps toward trade or colonisation, may have consisted of small fleets of balsa rafts.## "Tangaroa" (2006).In 2006,.

Kon-Tiki expedition. the Tangaroa Expedition recreated the "Kon-Tiki" voyage using a newly built raft, the "Tangaroa", named after the Māori sea-god Tangaroa. Tangaroa's six-man crew was led by Norwegian Torgeir Higraff and included Olav Heyerdahl, grandson of Thor Heyerdahl, Bjarne Krekvik (captain), Øyvin Lauten (executive officer), Swedish Anders Berg (photographer) and Peruvian Roberto Sala. "Tangaroa" was launched on the same day that "Kon-Tiki" had been—April 28—and it reached its destination on July 7, which was 30 days faster than Heyerdahl's Kon-Tiki which had taken 101 days for the voyage. Tangaroa's speed was credited to the proper use of guaras (centerboards).## "An-Tiki".On January.

Kon-Tiki expedition. 30, 2011, "An-Tiki", a raft modeled after "Kon-Tiki", began a 3000 (mi), 70-day journey across the Atlantic Ocean from the Canary Islands to the island of Eleuthera in the Bahamas. The expedition was piloted by four men, aged from 56 to 84 years, led by Anthony Smith. The trip was designed to commemorate the journey in an open boat of survivors from the British steamship "Anglo-Saxon", sunk by the German cruiser "Widder" in 1940. The raft ended its voyage in the Caribbean island of St Maarten, completing its trip to Eleuthera in the following year with Smith and a new.

Expedition "Kon-Tiki2" got its name because it had 2 crews from many nations: Norway, Russia, UK, Mexico, New Zealand, Sweden, and Peru. It sought to double down on Heyerdahl's voyage by sailing two rafts from South America to Polynesia and then back. Expedition leader was Torgeir Higraff from Tangaroa Expedition (2006). Øyvin Lauten and Kari Skår Dahl were captains on the first leg, while Signe Meling and Ola Borgfjord were captains on the second leg. The raft reached.

White-bellied sea eagle. is slightly larger than the male, and can measure up to 90 (cm) long with a wingspan of up to 2.2 (m), and weigh 4.5 (kg). Immature birds have brown plumage, which is gradually replaced by white until the age of five or six years. The call is a loud goose-like honking.Resident from India and Sri Lanka through Southeast Asia to Australia on coasts and major waterways, the white-bellied sea eagle breeds and hunts near water, and fish form around half of its diet. Opportunistic, it consumes carrion and a wide variety of animals. Although rated as "Least Concern" globally,.

A pair of white-bellied sea eagles performs skilful displays of flying before copulation: diving, gliding and chasing each other while calling loudly. They may mirror each other, flying 2 – 3 (m) apart and copying each other swooping and swerving. A talon-grappling display has been recorded where the pair will fly high before one flips upside down and tries to grapple the.

White-bellied sea eagle. The white-bellied sea eagle skins the victim as it eats it. It is exceptionally efficient at digesting its food, and disgorges only tiny pellets of fragmented bone, fur and feathers.A 2006 study of inland bodies of water around Canberra where wedge-tailed eagles and white-bellied sea eagles share territories showed little overlap in the range of prey taken. Wedge-tailed eagles took rabbits, various macropods, terrestrial birds such as cockatoos and parrots, and various passerines including magpies and starlings. White-bellied sea eagles caught fish, water-dwelling reptiles such as the eastern long-necked turtle and Australian water dragon, and waterbirds such as ducks, grebes.

White-bellied sea eagle. have become rare in Thailand and some other parts of southeast Asia. They are relatively abundant in Hong Kong, where the population increased from 39 to 57 birds between 2002 and 2009. A field study on Kangaroo Island in South Australia showed that nesting pairs in areas of high human disturbance (as defined by clearing of landscape and high human activity) had lower breeding success rates. In the Eyre Peninsula in South Australia, nests have been vacated as human activities have encroached on the eagles' territories. Elsewhere, the clearing of trees suitable for nesting has seen it largely disappear locally,.
