Digital tags recently developed at Woods Hole Oceanographic Institution
attach non-invasively to whales, then
release after a few hours. After this beaked whale was tagged, the
device recorded data about the animal's behavior and
information about the surrounding ocean environment. The
tags have increased scientists’ ability to learn how whales respond to
sonar. The research was conducted under a permit issued by the Bahamas
Department of Resources and under permit # 981-1707 issued by the
National Marine Fisheries Service under the authority of the Marine
Mammal Protection Act and the U.S. Environmental Protection Agency.
