    • Cetacean visual observations using line-transect survey methods onboard the NOAA Ship Gordon Gunter in the GOM, 6/29/2017 to 8/17/2017, GoMMAPPS survey (GU1703)

    Metadata Updated: June 1, 2025

    As part of the Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPPS), the Southeast Fisheries Science Center (SEFSC) conducted aerial surveys of the U.S. continental shelf waters (up to the 200-m isobath) in the Gulf of Mexico from 6/29/2017 to 8/17/2017. 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.
