A multi-objective research cruise was conducted in the northern Caribbean Sea and the adjacent Atlantic Ocean from 29 January through 8 March 1995. One aspect of the cruise was to determine the feasibility of using ship-based line-transect survey methods to estimate the abundance of cetaceans in waters of Puerto Rico and the U.S. Virgin Islands. Cetacean surveys were also conducted during daylight between ichthyoplankton sampling stations in the Atlantic Ocean east of the Virgin Islands, while in transit, and around Pedro Bank, Jamaica. Cetaceans were sighted 65 times (including three two-species sightings) and 4275 transect km were surveyed. At least nine cetacean species were identified, including (number of groups sighted) humpback whale (Megaptera novaeangliae), 12; minke whale (Balaenoptera acutorostrata), 1; sperm whale (Physeter macrocephalus), 8; Mesoplodon spp., 2; shortfin pilot whale (Globicephala macrorhynchus), 9; bottlenose dolphin (Tursiops truncatus), 3; Atlantic spotted dolphin (Stenella frontalis), 8; pantropical spotted dolphin (S. attenuata), 6; and striped dolphin (S. coeruleoalba), 1. Eighteen groups could not be identified to species.
