Garrison and Jenny Litz As part of GoMMAPPS, the Southeast Fisheries Science Center conducted aerial surveys of continental shelf waters (up to the 200-m isobath) in the U.S. Gulf of Mexico. The survey was conducted between 12 October and 28 November 2018 aboard a NOAA Twin Otter aircraft at an altitude of 600 feet (183 m) and a speed of 100-110 knots (185-204 kph). Survey tracklines were oriented perpendicular to the shoreline and latitudinally spaced 20 km apart. The survey was designed for analysis using Distance sampling with a two-team (independent observer) approach to correct for perception bias in resulting abundance estimates. download https://www.boem.gov/gommapps WWW:LINK-1.0-http--link Gommapps Home Page Online Resource download https://www.fisheries.noaa.gov/southeast/population-assessments/marine-mammal-research-surveys-noaas-southeast-region WWW:LINK-1.0-http--link NOAA Fisheries Population Assessment of Marine Mammals in SE Online Resource download Cite as: Litz, Jenny; Foster, Marjorie; Dias, Laura A.; Rappucci, Gina; Martinez, Anthony; Soldevilla, Melissa; Garrison, Lance; Mullin, Keith (2021).

The survey was designed for a two-team independent visual observer approach with distance sampling to estimate abundance and characterize spatial distribution of marine mammals and sea turtles. This dataset includes marine mammal and sea turtle visual observation data and effort points with surveying conditions that can be used in abundance and density modeling per visual line-transect survey protocols. This dataset also includes marine mammal photographs used to aid in species identification The primary goal was to collect data on the distribution and abundance of marine mammals and sea turtles in the U.S. continental shelf waters of the Gulf of Mexico (GOM) using two independent visual survey teams. completed Rappucci, Gina (305) 361-4283 75 Virginia Beach Drive Miami FL 33149 gina.rappucci@noaa.gov pointOfContact Dias, Laura A (305) 361-4269 75 Virginia Beach Drive Miami FL 33149 laura.dias@noaa.gov https://orcid.org/0000-0001-9378-4577 WWW:LINK-1.0-http--link ORCID Page Laura Dias Website listed for Dias, Laura A information pointOfContact Litz, Jenny 305-361-4224 305-365-4102 75 Virginia Beach Drive Miami FL 33139 Jenny.Litz@noaa.gov custodian asNeeded EARTH SCIENCE > BIOLOGICAL CLASSIFICATION EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > MAMMALS EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > MAMMALS > CETACEANS EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > MAMMALS > CETACEANS > BALEEN WHALES EARTH SCIENCE > BIOLOGICAL CLASSIFICATION > ANIMALS/VERTEBRATES > MAMMALS > CETACEANS > TOOTHED WHALES EARTH SCIENCE > BIOSPHERE > ECOLOGICAL DYNAMICS > COMMUNITY DYNAMICS > INDICATOR SPECIES EARTH SCIENCE > BIOSPHERE > ECOLOGICAL DYNAMICS > SPECIES/POPULATION INTERACTIONS EARTH SCIENCE > BIOSPHERE > ECOLOGICAL DYNAMICS > SPECIES/POPULATION INTERACTIONS > ENDANGERED SPECIES EARTH SCIENCE > CLIMATE INDICATORS > PALEOCLIMATE INDICATORS > BIOLOGICAL RECORDS > POPULATION ABUNDANCE theme Global Change Master Directory (GCMD) Science Keywords 17.0 CONTINENT > NORTH AMERICA OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF AMERICA place Global Change Master Directory (GCMD) Location Keywords 20.8 BINOCULAR > BINOCULAR CAMERAS VIDEO CAMERA > VIDEO CAMERA VISUAL OBSERVATIONS > VISUAL OBSERVATIONS instrument Global Change Master Directory (GCMD) Instrument Keywords 17.2 Airplane > Airplane NOAA Twin Otter > NOAA De Havilland DHC-6-300 Twin Otter platform Global Change Master Directory (GCMD) Platform Keywords 17.2 10.25921/y796-a161 theme DOI 14450 theme ESA/MMPA Permit Number GOMMAPPS > Gulf of Mexico Marine Assessment Program theme Global Change Master Directory (GCMD) Project Keywords M17PG00013 theme Interagency Agreement 0243468 theme NCEI ACCESSION NUMBER US DOC; NOAA; NMFS; Southeast Fisheries Science Center theme NODC COLLECTING INSTITUTION NAMES THESAURUS MARINE MAMMALS SPECIES IDENTIFICATION cetacean species abundance theme NODC DATA TYPES THESAURUS biological in situ marine mammal observation visual estimate visual observation theme NODC OBSERVATION TYPES THESAURUS Gulf of Mexico Marine Assessment Program for Protected Species (GOMMAPPS) theme NODC PROJECT NAMES THESAURUS Gulf of Mexico theme NODC SEA AREA NAMES THESAURUS US DOC; NOAA; NMFS; Southeast Fisheries Science Center; Miami, FL Laboratory theme NODC SUBMITTING INSTITUTION NAMES THESAURUS NA15OAR4320064 NA20OAR4320472 theme cooperative agreement oceanography theme wmo_categorycode binoculars camera photograph video camera instrument NODC INSTRUMENT TYPES THESAURUS CETACEANS DOLPHIN PHOTOGRAPHS SEA TURTLE SIGHTING VIDEO VISUAL OBSERVATIONS theme 2018 temporal AIRCRAFT DISTANCE SAMPLING LINE-TRANSECT SURVEY instrument DeHavilland DHC-6 Twin Otter aircraft platform DOC/NOAA/NMFS/SEFSC > Southeast Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Parameter or Variable: CETACEANS, VISUAL OBSERVATIONS (measured); Units: NA; Observation Category: In Situ/Laboratory Instruments, SPECIES DISTRIBUTION MODELS, POPULATION ABUNDANCE; Sampling Instrument: AIRCRAFT, LINE-TRANSECT SURVEY, DISTANCE SAMPLING; Sampling and Analyzing Method: The goal of the survey was to conduct line-transect surveys using the distance sampling approach to estimate the abundance and spatial distribution of marine mammals and sea turtles in waters over the continental shelf in the U.S. Gulf of Mexico. A two-team independent observer approach was used to correct for perception bias in resulting abundance estimates. Survey tracklines were oriented perpendicular to the shoreline and latitudinally spaced 20 km apart.; Data Quality Method: Data auditing consisted of making corrections based on error log notes from the field, plotting trackline points to identify errors made when recording effort status, and verifying sighting data based on data sheets from the field..
