Description:In summer 2021, the Pacific Islands Fisheries Science Center conducted a comprehensive line-transect survey for cetaceans and seabirds within the United States exclusive economic zones of Guam and the Commonwealth of the Northern Mariana Islands. The Mariana Archipelago Cetacean Survey (MACS) 2021 project was part of the multi-year Pacific Marine Assessment Program for Protected Species (PacMAPPS) plan to conduct surveys and estimate density for cetacean species in regions of joint NOAA Fisheries, Bureau of Ocean Energy Management, and U.S. Navy interest. MACS 2021 sailed for 59 days at sea aboard the NOAA Ship Oscar Elton Sette in May–July, 2021, and surveyed 8,711.7 km of trackline. The team conducted visual and passive acoustic surveys during daylight hours when weather permitted. There were 77 cetacean sightings of at least 12 species.
