Summary
ABSTRACT: A winter marine mammals survey in Gulf of Mexico was conducted in
1993 by NOAA Southeast Fisheries Science Center to examine the distribution and
estimate abundance of cetaceans in U.S. waters. The survey was followed by a
similar spring survey in 1993. 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 31 survey days, 10 species were sighted,
including Atlantic spotted dolphin Clymene dolphin Melon-headed whale
Pantropical spotted dolphin Pygmy sperm whale Short/Long-finned pilot whale
Sperm whale Standard Bottlenose dolphin Striped dolphin 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. Complete a line transect survey of the study area for marine mammals during
daylight hours following prescribed transects. 2. Collect ichthyoplankton
samples for the Southeast Area Monitoring and Assessment Program (SEAMAP)
during the non-daylight hours using neuston, bongo and Tucker trawls. 3. Obtain
associated environmental and oceanographic data.
