Description
Data from visual surveys in the Gulf of Alaska conducted to study cetaceans in 2003. more
Visual surveys for cetaceans were conducted in the Gulf of Alaska in association with a NOAA/Alaska Fisheries Science Center’s pollock stock assessment survey aboard the NOAA ship Miller Freeman from 26 June - 15 July 2003. Standard line-transect methods were used with three observers rotating through two 25x (Big Eye) binocular positions and one recorder on the flying bridge. Survey effort was conducted along the pollock survey transect lines, weather permitting. Additional effort was made while in transit to and from pollock survey waypoints. A total of 2,242 km of trackline were surveyed with 364 cetacean sightings (1,079 individuals). An additional 28 cetacean sightings were made (175 individuals) during off effort periods. Species included harbor porpoise (Phocoena phocoena), Dall’s porpoise (Phocoenoides dalli), Pacific white-sided dolphin (Lagenorhynchus obliquidens), killer whale (Orcinus orca), minke whale (Balaenoptera acutorostrata), fin whale (Balaenoptera physalus), humpback whale (Megaptera novaeangliae), sperm whale (Physeter macrocephalus), Baird’s beaked whale (Berardius bairdii), and Cuvier’s beaked whale (Ziphius cavirostris).
