Mullin, Katherine S. Maze, & Carrie W. Hubard, NOAA Southeast Fisheries Science Center Abstract: A continental shelf cetacean survey in northern Gulf of Mexico was conducted in 1998 by NOAA Southeast Fisheries Science Center and Minerals Management Service 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. During the 6 survey days, 42 cetacean groups were sighted, including Atlantic spotted dolphin Bottlenose dolphin Pilot whale The dataset is accompanied by transect data which is provided as a separate file.

Specific objectives of this survey are: 1. Collect line-transect data to estimate abundance and define distribution of cetacean species in continental shelf waters of the northern Gulf of Mexico. 2. Obtain biopsy samples of skin and blubber from selected cetacean species for genetic and contaminant analysis in order to study the stock structure of Gulf of Mexico cetaceans. 3. Collect ichthyoplankton samples with bongo and neuston gear for Gulf-wide estimates of abundance, frequency of occurrence, and distribution of larval and small juvenile king and Spanish mackerel, red drum, snappers, and other taxa. 4. Collect associated environmental data at designated stations in order to define cetacean habitats. notPlanned Lance Garrison NOAA Southeast Fisheries Science Center Primary contact lance.garrison@noaa.gov NA NA NA Lance Garrison owner NA zd_31 2025-07-31T14:02:45-04:00 dataset Garrison, L. 2020.
