The first of two spring vessel surveys of the GulfCet II Program was conducted in 1996 in oceanic and upper continental slope waters of U.S. Gulf of Mexico 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.
During the 44 survey days, at least 16 species were sighted, including
Pygmy sperm whale
Dwarf sperm whale
Cuvier's beaked whale
Pantropical spotted dolphin
Atlantic spotted 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.
Specific objectives of this survey are:
1. Collect line-transect data to estimate abundances and define the distributions of cetacean species in oceanic and selected continental shelf waters of the northern Gulf of Mexico.
2. Obtain biopsy samples of skin from selected cetacean species for genetic analysis in order to study the stock structure of Gulf of Mexico cetaceans.
3. collect associated environmental data at designated stations in order to define cetacean habitats.
4. Collect data on the distribution and abundance of seabirds and other marine life.
5. Collect data on species identity, distribution and abundance, and stock structure of flyingfish.
It turned out that the records were duplicated (two completely identical data were added). The duplication was discarded on 2012-05-08.

The dataset contains information necessary to locate the species sightings observed in the survey. The structure of the dataset was defined by NOAA Southeast Fisheries Science Center. Note that the dataset is a subset of the larger, complete dataset collected in the survey which includes environmental information. The columns before LineNo are applied to the shapefile only. The following information is not included in the dataset but will be found in the master data. For details, please contact NOAA Southeast Fisheries Science Center. Track; Speed; GPS Status; Observers; Wind direction; Weather; Sea state; Swell; Visibility; Turbidity; Sunlight; Water depth; Water color; Water temperature; Sighting angle; Effort status.
