PIFSC, Cetacean Survey, Guam-Hawaii Transit 2010, Cruise 1004, NOAA Pacific Islands Fisheries Science Center

Original provider: NOAA Pacific Islands Fisheries Science Center (PIFSC) Dataset credits: NOAA Pacific Islands Fisheries Science Center Abstract: The Pacific Islands Fisheries Science Center conducted cetacean surveys aboard the NOAA Oscar Elton Sette during the ship's transit from Guam to Hawaii (19 April - 4 May 2010) and covered 2,719 km of on-effort trackline. There were 23 cetacean sightings, 15 of which were identified to five species. Time and weather limitations prevented the ship’s approach of more of the sighted cetacean groups. 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 DAS 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. A High-frequency Acoustic Recording Package (HARP) was recovered and redeployed off Wake Island. Oceanographic data were collected (CTD, XBT, continuous plankton recorder).
