DTAG Support: Tagging Beaked Whales in the North Atlantic

Alessandro Bocconcelli, Woods Hole Oceanographic Institution

ABSTRACT

The goal of the project is to study the behavior of beaked whales in the North Atlantic offshore the U.S. coast. The proposed work takes advantage of the digital acoustic recording tag (DTAG) developed at Woods Hole Oceanographic Institution (WHOI) for studying the behavior of marine mammals in the wild. The National Oceanic and Atmospheric Administration (NOAA) Northeast Fisheries Science Center’s (NEFSC’s) Passive Acoustic Research Group will be conducting the field component of this project. The recording tag is attached non-invasively to the back of the whales using suction cups. Once released, the tag floats to the surface and it is recovered using radio-tracking. A large memory array on the tag stores raw sensor data.
