66009 PC-18-05 Marine Mammal Visual Observations Data Data Set Published / External 67243 Gulf of Mexico Marine Assessment Program for Protected Species Project Completed 2018 2021 As part of the Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPPS), the Southeast Fisheries Science Center (SEFSC) conducted shipboard surveys of the U.S. oceanic waters of the Gulf of Mexico out to the Exclusive Economic Zone (EEZ) from 2018-08-12 to 2018-10-05. The survey was designed for a two-team independent visual observer 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 (occurrences) such as sea turtles. Raw and processed files from conductivity, temperature and depth (CTD) and expendable bathythermograph (XBT) casts performed on a daily basis during the survey are also available. To collect data on the distribution and abundance of marine mammals in the U.S. waters of the Gulf of Mexico (GOM) using two independent visual survey teams.

A two-team independent observer approach using pedestal-mounted 25x150 mm “big eye” binoculars was used to correct for perception bias in resulting abundance estimates. Survey tracklines were oriented perpendicular to bathymetry lines and followed a “sawtooth” pattern from approximately the 100m-isobath to the Exclusive Economic Zone. https://www.boem.gov/sites/default/files/environmental-stewardship/Environmental-Studies/GOMR/Oceanography/GoMAPPS/NOAA-Ship-Survey-January-March-2018.pdf; 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.
