Description
Original provider: NOAA Pacific Islands Fisheries Science Center (PIFSC) Dataset credits: NOAA Pacific Islands Fisheries Science Center Abstract: In summer 2021, the Pacific Islands Fisheries Science Center conducted a comprehensive line-transect survey for cetaceans and seabirds within the United States exclusive economic zones of Guam and the Commonwealth of the Northern Mariana Islands. MACS 2021 sailed for 59 days at sea aboard the NOAA Ship Oscar Elton Sette in May–July, 2021, and surveyed 8,711.7 km of trackline. There were 77 cetacean sightings of at least 12 species.
Data Records

Additional Metadata
marine, harvested by iOBIS. 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. Drifting Acoustic Spar Buoy Recorders (DASBRs) were deployed and recovered opportunistically. High-frequency Acoustic Recording Packages (HARPs) were recovered and redeployed off Saipan and Pagan.
| Purpose | The Mariana Archipelago Cetacean Survey (MACS) 2021 project was part of the multi-year Pacific Marine Assessment Program for Protected Species (PacMAPPS) plan to conduct surveys and estimate density for cetacean species in regions of joint NOAA Fisheries, Bureau of Ocean Energy Management, and U.S. Navy interest. |
