Description

Original provider: NOAA Pacific Islands Fisheries Science Center (PIFSC) Dataset credits: NOAA Pacific Islands Fisheries Science Center Abstract: In April 2019, the NOAA Pacific Islands Fisheries Science Center and Hawaiian Islands Humpback Whale National Marine Sanctuary conducted a collaborative exploratory ship-based survey for humpback whales (Megaptera novaeangliae) in the Papahānaumokuākea Marine National Monument (PMNM) aboard the NOAA Oscar Elton Sette. During the 6-day effort the shallow atolls and banks extending from Middle Bank (north of Kauai) to St. Rogatien Banks (north of French Frigate Shoals) were surveyed. There were 60 cetacean sightings, most of which were humpback whales. Supplemental information: Data were collected under NMFS permit 20311. 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.
Oceanographic data were collected (CTD).
