Hill NOAA Pacific Islands Fisheries Science Center Primary contact Marie.Hill@noaa.gov owner 2025-09-29 eng Original provider: NOAA Pacific Islands Fisheries Science Center (PIFSC) Dataset credits: NOAA Pacific Islands Fisheries Science Center Abstract: The Hawaiian Islands Cetacean and Ecosystem Assessment Survey (HICEAS) of 2017 was a large-scale ship survey for cetaceans and seabirds within U.S. waters surrounding the Hawaiian Islands. HICEAS 2017 was the third of its kind using many of the same methods and encompassing the same study area as surveys which occurred in 2002 (Barlow et al. 2006) and 2010 (Bradford et al. 2017). The 2017 survey represented the first Cetacean and Ecosystem Assessment Survey conducted as part of the Pacific Marine Assessment Program for Protected Species (PacMAPPS), a partnership between NOAA Fisheries, Bureau of Ocean Energy Management (BOEM), U.S. Navy, and U.S. Fish and Wildlife Service. PacMAPPS includes rotational ship surveys in regions of joint interest throughout the Pacific designed to estimate the abundance of cetaceans and seabirds and to assess the ecosystems supporting these species. HICEAS 2017 was a collaborative survey between the Pacific Islands and Southwest Fisheries Science Centers (PIFSC and SWFSC). The survey took place from 6 July to 1 December 2017, aboard the NOAA Ships Oscar Elton Sette and Reuben Lasker, spanning 7 survey “legs” and 179 days-at-sea across both ships.

These are fixed. Data from survey legs aboard Oscar Elton Sette (Cruise ID: 1706) and Reuben Lasker (Cruise ID: 1705) were merged. Survey tracks include on-effort segments only. Attributes for fields within the trackline files: Cruise - see description in attribute table below segnum - segment number for continuous on-effort line Date - Local date m/dd/yyyy TimeStart - Local time at start of on-effort segment LatStart - Latitude in decimal degrees at starting point of on-effort segment LongStart - Longitude in decimal degrees at starting point of on-effort segment TimeEnd - Local time at end of on-effort segment LatEnd - Latitude in decimal degrees at end point of on-effort segment LongEnd - Longitude in decimal degrees at end point of on-effort segment Mode - see description in attribute table below EffType - see description in attribute table below avgSpdKt - average speed (knots) of the ship over the on-effort segment traveled avgBft - average Beaufort Sea State over the on-effort segment This work is licensed under a Creative Commons Attribution Non Commercial (CC-BY-NC) 4.0 License. https://seamap.env.duke.edu/dataset/2180 Western Pacific sector, North Pacific,Hawaii,California 177.96217 180 32.01767 16.5585 Eastern Pacific sector, North Pacific,Hawaii,California -180 -120.11417 32.01767 16.5585 2017-07-08 2017-11-30 Scientific names are based on the Integrated Taxonomic Information System (ITIS). genus Balaenoptera Baleen whales species Balaenoptera acutorostrata Common minke whale species Balaenoptera brydei Bryde's whale species Balaenoptera musculus Blue whale species Balaenoptera physalus Fin whale family Balaenopteridae Rorquals order Cetacea Cetaceans family Delphinidae Dolphins species Delphinus delphis Short-beaked common dolphin species Feresa attenuata Pygmy killer whale species Globicephala macrorhynchus Short-finned pilot whale species Grampus griseus Risso's dolphin family Hyperoodontidae Beaked whales species Indopacetus pacificus Longman's beaked whale genus Kogia Pygmy sperm whales species Kogia breviceps Pygmy sperm whale species Lagenodelphis hosei Fraser's dolphin species Megaptera novaeangliae Humpback whale genus Mesoplodon Beaked whales species Mesoplodon densirostris Blainville's beaked whale species Orcinus orca Killer whale species Peponocephala electra Melon-headed whale species Physeter macrocephalus Sperm whale species Pseudorca crassidens False killer whale species Stenella attenuata Pantropical spotted dolphin species Stenella coeruleoalba Striped dolphin species Stenella longirostris Spinner dolphin species Steno bredanensis Rough-toothed dolphin species Tursiops truncatus Common bottlenose dolphin species Ziphius cavirostris Cuvier's beaked whale The primary goals of HICEAS 2017 were to collect data required to estimate the abundance and distribution, examine the population structure, and understand the habitat of cetaceans within U.S. waters around the Hawaiian Islands. There were 5 major research components to HICEAS 2017: ● visual observations for cetaceans following a line-transect survey design; ● passive acoustic monitoring for cetaceans using towed hydrophone arrays, sonobuoys, and autonomous drifting acoustic recorders; ● collection of photographs and tissue samples and deployment of satellite tags for select cetacean groups; ● visual observations for seabirds following a strip-transect survey design; and ● ecosystem measurements for assessment of cetacean and seabird habitat. notPlanned Marie C.
