A Eastern Gulf of Mexico cetacean survey was conducted in 1994 by NOAA Southeast Fisheries Science Center to examine the distribution and estimate abundance of cetaceans in U.S. waters. This dataset contains sightings of not only cetaceans but also other species including sea turtles, fish and shark observed during the ship survey.
Sighted species numbers 299 herds composed of 4,370 total individual animals, including
Atlantic spotted dolphin
Cuvier’s beaked whale
Pantropical spotted dolphin
Standard Bottlenose dolphin
The dataset is accompanied by transect data which is provided as a separate file.
The purpose of this survey is to examine the distribution and estimate abundance of cetaceans in U.S. waters, which should meet the responsibility under the Marine Mammal Protection Act and the Endangered Species Act.
Specific objectives of this survey are:
1. Collect data to estimate abundances and define the distributions of marine mammals in the eastern Gulf of Mexico.
2. Collect associated environmental data at designated stations.
3. Obtain biopsy samples of skin and blubber from selected cetacean species.
4. Conduct a shallow water (10 to 20 fathoms) experiment on dolphin attraction to a vessel.
5. Collect data on the distribution and abundance of sea turtles, seabirds and other marine life.
6. Collect data on the distribution and type of marine debris encountered during the survey.
