A contemporary Duke University led study offers the elemental detailed record of the diving conduct of Cuvier’s beaked whales in U.S. Atlantic waters. Cuvier’s beaked whales are the world’s profound diving mammal but scrutinization of their behavior is contrived by the animal’s waterside location and restricted time disbursed at the surface.
The contemporary data chronicled from 5,926 dives of tagged whales off Cape Hatteras, N.C. portrays the extraordinary diving abilities of these animals and offers contemporary clues on how they survive in the depths of extreme cold.
Jeanne Shearer, a doctoral student in ecology at Duke University’s Nicholas School of the Environment said that their profound dives norm about 1,400 meters, remaining for an hour while they are sustaining near the sea floor.
They habitually only disburse about two minutes at the surface between dives. It’s a spectacle to see that they can dive to such depths confront the pressure and sustain for a time span with such short recovery times.
Past research has chronicled the diving behavior of Cuvier’s beaked whales in Pacific waters, Italy, and the Bahamas, but this is an elemental one concentrating in the U.S. Atlantic. Scientists appraise about 6,500 Cuvier’s beaked whales residing in the Northwest Atlantic. Populace in various regions displays certain disagreements in diving behavior underscoring the requirement of data from around the globe.
To carry out the study scientists connected LIMPET satellite-linked tags to 11 Cuvier’s beaked whales that reside and dive the majority of the time of the year in water, a two-hour boat ride from Cape Hatteras.
