The data were collected by U.S.G.S. biologists and their partners during several field trips from March 2013 to April 2014 in Guantanamo Bay, Cuba. Data were collected during the manatee health assessments. The U.S. Geological Survey’s Sirenia Project is a federal research effort focusing on manatee biology and ecology with a long history of studies in the U.S., Puerto Rico, and the international arena. The status of the Antillean manatee in Cuba is not well known. Manatee population census techniques are mostly prohibited due to regulation of the airspace, but it is speculated that the population of manatee in Cuba is not very large. Manatee captures will enable health assessments and radio tagging to determine movement patterns.
