More than 650 volunteers gathered data from the shores of Oahu, Kauai, the Big Island and Kahoolawe for the annual Hawaiian Islands Humpback Whale National Marine Sanctuary Ocean Count on Saturday, Jan. 31. Participants tallied humpback whale sightings and documented the animals’ surface behavior during the survey. The sanctuary, which is managed by NOAA, protects humpback whales and their habitat in Hawaiian waters where they migrate each winter to mate, calve and nurse their young.
Volunteers collected data from 56 sites statewide. Every 15 minutes, an average of eight whales were counted per site statewide. The following are the average numbers of whales sighted per 15-minute count period on each of the islands:
O‘ahu – four whales
Kaua‘i – eight whales
Big Island – five whales
Kaho‘olawe – 14 whales
Scientific studies have shown that Hawaii’s humpback whale population has been increasing at an annual rate of approximately seven percent. Over time, data from the Sanctuary Ocean Count can be used to corroborate these findings. Hawaiian waters provide critical breeding habitat for approximately two-thirds of the north Pacific stock of humpback whales.
“It was great to see so many new volunteers taking part in this month’s count,” said Christine Brammer, sanctuary ocean count coordinator. “The Ocean Count project provides a unique opportunity for the public to learn about Hawaii’s humpbacks while participating in a monitoring effort. Many volunteers that try out the project come back year after year. It is easy to get hooked on watching Hawaii’s humpbacks.”
Two more Sanctuary Ocean Counts are scheduled to take place on Saturday, Feb. 28 and March 28.
