Identifying beaked whale foraging habitat in the tongue of the ocean, Bahamas
Date:4/27/2011

In a recent study to be published on April 27, 2011, in the peer-reviewed open-access journal PLoS ONE, Dr. Elliott Hazen and colleagues found that oceanographic and prey measurements can be used to identify beaked whale foraging habitat. The research team from Duke University, Woods Hole, and the Naval Undersea Warfare Center listened for foraging beaked whales and measured ocean features and distributions of prey off the east coast of Andross Island in the Bahamas.

Their manuscript provides evidence that these difficult to study deep-diving creatures use specific ocean features such as salinity and temperature to find their prey. This is the first study describing their distribution and feeding habitat relative to ocean features Blaineville's beaked whales regularly dive over 1000 meters for over an hour in search of prey which varies from 400-1000 meters. The shy and elusive toothed whales feed primarily on fish and squid in the ocean's deep scattering layer, an important prey resource for many species throughout the world's oceans. In addition, Blaineville's beaked whales are listed as data deficient by the IUCN, and very little is currently known about the ecology of these creatures. Beaked whale species are thought to be sensitive to noise arising from certain human activities; in 2000, beaked whale strandings were observed coinciding with naval sonar exercises in the Bahamas. Understanding the distribution and behavior of these species is important to minimize harmful impacts from human uses of the ocean. Researchers worked aboard the R/V Revelle, an 86-meter vessel out of Scripps Institute of Marine Science. Fisheries acoustics data found scattering layers of prey on the western edge of the tongue of the ocean were denser than those at the eastern edge. Eighty-two bottom-mounted hydrophones also recorded increased foraging activity on the western edge of the basin.

The hydrophone range at AUTEC allowed for unprecedented measu
