(abstract in English and Spanish)
In the summer of 1991, we conducted marine mammal surveys in the Gulf of
Mexico, Caribbean Sea, and a small portion of the southwestern North
Atlantic.  A total of 193 hours of survey effort was conducted, and there
were 60 marine mammal sightings.  Species identified (number of
sightings in parentheses) were: sperm whale Physeter catodon L. (6),
Cuvier's beaked whale Ziphius cavirostris G. Cuvier (1), short-finned pilot
whale Globicephala macrorhychus Gray (1), rough-toothed dolphin Steno
bradanensis (Lesson) (1), bottlenose dolphin Tursiops truncatus (Montagu)
(6), Atlantic spotted dolphin Stenella frontalis (G. Cuvier) (2),
pantropical spotted dolphin S. attenuata (Gray) (10), spinner dolphin S.
longirostris (Gray) (1), and striped dolphin S. coeruleoalba (Meyen) (3).
Distribution of sightings was largely related to sighting conditions, but
there were concentrations of sightings in areas with high sea floor relief-
in the Straits of Florida, the area west fo Martinique, and along the
Mexican Ridge.
