This dataset represents the surveys (4 Legs) aboard the MacArthur II that began and ended in LaJolla, CA (4 August - 10 December). There were 290 cetacean sightings which included 22 identified species as well as unidentified dolphins, large whales and beaked whales.

[2023-09-06] Some of the sightings got their group sizes estimated incorrectly. These are fixed. 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).
