NOAA Northern Gulf of Mexico Cetacean Survey 1998; Sightings
Entry ID: seamap31

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.

Purpose: 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 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 ... View entire text
