Tracking Killer Whales with Technology

SHARE THIS:

WHOI researchers will use a small, non-invasive piece of technology, the digital archival tag or D-tag, in November to tag free-ranging killer whales in northern Norway. The researchers will record the sounds and movements of these animals as part of a study to understand the relationship between their vocalizations and highly coordinated group foraging behavior. The D-tag, developed by WHOI scientists and engineers, has been used to study a variety of whales and dolphins, including sperm whales, beaked whales, humpback whales, narwhals and killer whales.
