Cetacean visual observations and environmental parameters collected by conductivity, temperature and depth (CTD) and other instruments onboard the NOAA Ship Gordon Gunter (GU) in the Gulf of America (survey GU1404) from 2014-07-05 to 2014-07-29 (NCEI Accession 0317335)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 09:48 PM | Dataset Last Updated: August 07, 2026 at 12:00 AM
The Southeast Fisheries Science Center (SEFSC) conducted a marine mammal survey in the offshore waters along the inner continental slope off the Dry Tortugas from 2014-07-04 to 2014-07-29. This project was conducted jointly with the Bureau of Ocean Energy Management (BOEM) to support environmental assessments associated with potential offshore energy exploration projects in the southeastern Gulf and to improve understanding of potential critical habitat areas for the Northern Gulf sperm whale (Physeter macrocephalus) population. The survey was designed with a focus on sperm whales, although sightings of other species were also recorded. 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, marine mammal photographs, marine mammal biopsy samples, and non-marine mammal sightings (a.k.a. occurrences) such as sea turtles. Raw and processed files from conductivity, temperature and depth (CTD) and expendable bathythermograph (XBT) casts performed during the survey are also available.
