Cruise results, NOAA Ship Gordon Gunter cruise GU-01-01 (11), 6 February - 3 April 2001 : marine mammal survey of Puerto Rico and a study of sperm whales in the southeastern Gulf of Mexico Marine mammal survey of Puerto Rico and a study of sperm whales in the southeastern Gulf of Mexico NOAA Ship Gordon Gunter Cruise GU-01-01 (11), 6 February - 3 April 2001

"A visual and acoustic survey for humpback whales and other marine mammals was conducted from 6 February to 14 March 2001 in the waters to the east of the Bahamas and around Puerto Rico and the Virgin Islands. This was followed by a survey for sperm whales and other marine mammals in the eastern Gulf of Mexico from 16 March to 3 April 2001. Both surveys utilized passive acoustic techniques to augment traditional visual surveys for marine mammals. The first survey (Legs 1 and 2) relied primarily on directional sonobuoys for acoustic detections of whales, while the second survey (Leg 3) primarily utilized a towed hydrophone array for detection and tracking of sperm whales. Lists of the species encountered and their distributions are presented in 11 tables and 14 figures that accompany the text. Some photographic identification photographs and biopsy samples were obtained"--Summary. Carolyn Burks, Keith D. Mullin, Steven L. Swartz and Anthony Martinez. "August 2001."
