Gulf of Mexico Marine Mammal Assessment Vessel Surveys

Metadata Updated: February 8, 2018

These data sets are a compilation of large vessel surveys for marine mammal stock assessments in the Gulf of Mexico from 1991 to the present. These are designed as line-transect surveys which typically follow a double saw-tooth pattern covering waters between the continental shelf break (approx. 200m depth) and the U.S. Economic Exclusivity Zone. Visual survey data are collected following standard protocols and are intended for analysis using the line-transect Distance method to provide estimates of abundance for marine mammal stocks within the survey area. Each survey includes a collection of data sets including visual survey data (survey effort and sightings of marine mammals and other species), passive and active acoustics data, sample collection information, and physical oceanographic data. These data have been used to develop estimates of population size for target species for use in annual Marine Mammal Protection Act stock assessment reports.
