The Cetacean Assessment and Ecology Program (CAEP) is responsible for conducting studies to assess the status of cetaceans in Alaskan waters under the Endangered Species Act and the Marine Mammal Protection Act. Major CAEP projects have included studies of North Pacific right whales, bowhead whales, gray whales, humpback whales, beluga whales, killer whales, Dall’s porpoise, and harbor porpoise. Other species included in CAEP research are blue whales, fin whales, sei whales, minke whales, sperm whales, beaked whales (including Cuvier’s, Baird’s, and Stejneger’s), and Pacific white-sided dolphins. Most research projects involve determination of abundance, trends, stock structure, habitat use, and feeding ecology using aerial and vessel surveys, shore-based counts, acoustic studies, radio and satellite tagging, genetic studies, photo-identification of individual animals, and opportunistic sighting data. CAEP uses the results of these stock assessments to provide the scientific advice necessary to manage cetaceans in Alaskan waters. CAEP scientists also collaborate widely with other national and international research groups working on cetaceans across the North Pacific and, sometimes, in other oceans.
