In 2003, Stacy DeRuiter arrived as a graduate student at Woods Hole Oceanographic Institution (WHOI), where a new device developed at WHOI was sparking a revolution in marine mammal research: the D-tag. The cell phone-size […]
Scientists tag whales and find they sprint-dive to forage, hunting like undersea cheetahs.
Eight years ago, several U.S. Navy destroyers used sonar in the Bahamas during routine training exercises. Within 36 hours, 17 animals—including 14 beaked whales, one of the world’s deepest-diving whale species—were found on three islands […]
For years, sperm whales and elephant seals were thought to hold world records for holding their breath under water. But those animals have nothing on beaked whales.
Using digital tags temporarily suction-cupped to two species of […]
For the first time in history, we can accompany a whale on its dive, hear what it hears, and observe its normal, natural, previously hidden behavior in the depths. Working closely together, scientists and engineers have created an innovative new device—the digital acoustic recording tag, or D-tag. It attaches to a living whale and records nearly everything that happens on its dives, without disturbing the animal.
