The Hawaiian Islands Cetacean and Ecosystem Assessment Survey (HICEAS) was a 179-day survey for whales, dolphins, and seabirds within the Hawaiian Archipelago, from shore to 200 nmi offshore. There were four major research components to HICEAS: visual observations for cetaceans, including photo-identification, biopsy sampling, and satellite tagging; passive acoustic monitoring using towed hydrophone arrays and other tools; ecosystem assessment, including visual surveys for seabirds and measurement of oceanographic variables (CTD casts, EK-60); and conduct other ancillary projects, such as aerial photogrammetry using a hexacopter, testing of new passive acoustic tools, and other projects that support and augment our assessment mission.
