72376 Document Published / External 72373 Cetacean visual observations using line-transect survey methods onboard the NOAA Ship Gordon Gunter (GU) during the Atlantic Marine Assessment Program for Protected Species (AMAPPS) in the Western North Atlantic Ocean (survey GU2301) from 2023-02-04 to 2023-04-27. (NCEI Accession 0290563) Data Set Completed 2023-11 As part of the Atlantic Marine Assessment Program for Protected Species (AMAPPS), the Southeast Fisheries Science Center (SEFSC) conducted shipboard surveys of the U.S. waters of the Western North Atlantic (WNA) from approximately the 200m isobath out to the U.S. Exclusive Economic Zone (EEZ). The survey was conducted between January 23 and April 28, 2023 onboard the NOAA Ship Gordon Gunter, for a total of 44 days at sea split into three survey legs. Multiple days were lost due to mechanical problems with the ship and unfavorable weather conditions. The survey design was similar to other SEFSC line-transect surveys in the Atlantic Ocean and Gulf of Mexico (Garrison et al., 2016; Rappucci et al., 2019). The ship surveyed along prescribed tracklines in a "double saw-tooth" configuration perpendicularly oriented to bathymetry lines. The main goal of this survey was to collect data on the distribution and abundance of marine mammals in the U.S. waters of the WNA using visual survey teams and passive acoustic detections Southeast Fisheries Science Center Reference Document PRBD-2023-05 10.25923/gtac-4j18 NOAA Central Library Theme NOAA Institutional Repository 56116 Theme Cetacea Populations Theme estimates Temporal 2023 Spatial North Atlantic Ocean Cruise Report Acrobat Portable Document Format Final Author 2023 Organization Southeast Fisheries Science Center SEFSC https://ror.org/0396y0w87 75 Virginia Beach Drive Miami FL 33149 USA (305)361-5761 https://www.fisheries.noaa.gov/about/southeast-fisheries-science-center About SEFSC Online Resource 8:00 a.m. - 4:30 p.m. EST Author 2023 Person Soldevilla, Melissa melissa.soldevilla@noaa.gov 75 Virginia Beach Drive Miami FL 33149 USA 305-361-4238 Author 2023 Person Dias, Laura A laura.dias@noaa.gov https://orcid.org/0000-0001-9378-4577 75 Virginia Beach Drive Miami FL 33149 (305) 361-4269 https://orcid.org/0000-0001-9378-4577 ORCID Page Laura Dias Online Resource Author 2023 Person Walsh, Harvey J harvey.walsh@noaa.gov 28 Tarzwell Drive Narragansett RI 02882 Author 2023 Person Garrison, Lance Lance.Garrison@noaa.gov 75 Virginia Beach Dr Miami FL 33149 305-361-4488 305-361-4478 8:00 AM - 4:30 PM EST/EDT Author 2023 2025-02 Person Martinez, Anthony anthony.martinez@noaa.gov 75 Virginia Beach Drive Miami FL 33149 USA 305-361-4486 305-361-4478 Distributor 2023 Organization NOAA Central Library library.reference@noaa.gov 1315 East-West Highway SSMC3, 2nd Floor Silver Spring MD 20910 United States (301) 734-2607 ext. 157 https://library.noaa.gov/ HomePage NOAA Central Library Online Resource 8:00 AM 4:30 - PM Unclassified This cruise report is used for documentation and timely communication of preliminary results immediately following the conclusion of the survey.
