This contains the photos in .jpg format embedded with the exchangeable image file (EXIF) metadata recorded by the cameras (e.g., time, date, camera settings) as well as metadata tags specific to the research (e.g., project name, permit number). In addition to other attributes, file names contain the survey code (surveyEventID), sighting number and the original file name for the media file. If present, non-mammal photos are assigned MISC (miscellaneous). Photos are organized by collection date and divided into subdirectories that correspond to the sighting number (starting at one and numbered consecutively on each day of the survey) of that date. Subdirectories are defined as: The nested file structure for photos may be as follows: YYYYMMDD (Y=year, M=month, D=day) Sighting_XXX Sighting_XXX E.g.: 20181027 (27 October 2018) Sighting_026 The primary goal was to collect photographic 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.

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..
