In the summer of 2004, the Southeast Fisheries Science Center (SEFSC) conducted a marine mammal survey in the northern Gulf of America. Operations occurred in the waters from 200 m deep seaward to the Exclusive Economic Zone (EEZ) from Brownsville, Texas east into the Straights of Florida. The survey was designed using ship-based, line-transect methods in which experienced marine mammal observers visually located marine mammals, identified the species (to the lowest taxonomic level possible) and counted the number of whales and dolphins sighted along predetermined track-lines. A sighting constitutes a group of marine mammals (whales and dolphins) seen at the same location and time. 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 information on biopsy samples collected during the survey. The primary goal was to conduct visual line-transect survey for abundance estimation, and distribution of cetaceans in the U.S. waters of the Gulf of America.

A single-team observer approach was used. Survey tracklines were oriented perpendicular to bathymetry lines and followed a “sawtooth” pattern.; Data Quality Method: Data auditing consisted of making corrections based on 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. dataset Previous title: Cetacean visual observations using line-transect survey methods onboard the NOAA Ship Gordon Gunter (GU) in the Gulf of Mexico (survey GU0402) from 2004-04-15 to 2004-06-10 (NCEI Accession 0284773) The title of the dataset has been updated by the NOAA National Centers for Environmental Information to reflect geographic name changes consistent with EO 14172. 2025-11-14T15:32:08Z asNeeded Metadata are developed, maintained and distributed by NCEI.
