    • Cetacean visual observations using line-transect survey methods onboard the NOAA Ship Gordon Gunter in the Gulf of Mexico, January through March 2018, GoMMAPPS survey (GU1801)

    Metadata Updated: November 1, 2024

    As part of the GoMMAPPS, the SEFSC conducted shipboard surveys of the oceanic waters of the Gulf of Mexico out to the U.S. Exclusive Economic Zone (EEZ) between 14 January and 16 March 2018. The survey was designed for a two independent visual observer teams approach with Distance sampling to estimate the detection probabilities for marine mammal sightings. This dataset includes marine mammal 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 opportunistic marine mammal photographs and non-marine mammal sightings such as sea turtles. Raw and processed files from Conductivity, temperature and depth (CTD) casts performed on a daily basis during the survey are also available.
