Original provider: NOAA Pacific Islands Fisheries Science Center (PIFSC) Dataset credits: NOAA Pacific Islands Fisheries Science Center Abstract: The Hawaiian Islands Cetacean Ecosystem Assessment Survey (HICEAS) was a collaborative project between the Southwest and Pacific Islands Fisheries Science Centers during which two NOAA ships (MacArthur II and Oscar Elton Sette) conducted line-transect surveys throughout the entire Hawaii exclusive economic zone (EEZ) over four months (August - December 2010). This dataset represents the surveys (2 Legs) aboard the Oscar Elton Sette that began and ended in Honolulu, HI (1 September - 29 October). There were 133 cetacean sightings which included 17 identified species as well as unidentified dolphins, large whales and beaked whales. Purpose: HICEAS 2010 was the second Hawaii EEZ-wide survey. The sighting data were used to estimate the abundance and distribution of cetaceans in Hawaiian waters (Bradford et al. 2017, 2021). Supplemental information: Data were collected under NMFS permit 14097. The data included here are the sightings and on-effort tracks recorded within WinCruz survey software and extracted from the QA/QC'd DASALL file using the R package swfscDAS (https://smwoodman.github.io/swfscDAS). 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 Other data not included here: Photos and biopsy samples were collected during some sightings. Acoustic detections were recorded from a towed hydrophone array. Sonobuoys were deployed opportunistically. Oceanographic data were collected (CTD, XBT).

摘要：夏威夷群岛鲸类生态系统评估调查（Hawaiian Islands Cetacean Ecosystem Assessment Survey, HICEAS）是西南渔业科学中心（Southwest Fisheries Science Center, SWFSC）与太平洋岛屿渔业科学中心的合作项目，期间两艘NOAA船舶（麦克阿瑟二世号（MacArthur II）与奥斯卡·埃尔顿·塞特号（Oscar Elton Sette））于2010年8月至12月的四个月间，在整个夏威夷专属经济区（exclusive economic zone, EEZ）开展了线样带调查。本数据集对应“奥斯卡·埃尔顿·塞特号”的两次航次（2 Legs），该船于夏威夷檀香山起航并返航，作业时段为2010年9月1日至10月29日。本次调查共记录133次鲸类目击事件，涉及17个已确定物种，以及未分类的海豚、大型鲸类和喙鲸。
调查目的：HICEAS 2010是第二次覆盖全夏威夷专属经济区的鲸类调查。目击数据被用于估算夏威夷海域鲸类的种群丰度与分布（Bradford等人，2017、2021）。
补充信息：本数据采集自国家海洋渔业局（National Marine Fisheries Service, NMFS）许可14097项下。此处提供的数据为WinCruz调查软件记录的目击事件与有效作业航迹，并通过R包swfscDAS从经过质量控制与质量保证（QA/QC）处理的DASALL文件中提取（https://smwoodman.github.io/swfscDAS）。
