Additional interests include diving physiology, energetics and marine mammal competition with fisheries and aquaculture. They have been successfully applied to bowhead whales, manatees, gray whales, blue whales, humpback whales, right whales, bottlenose dolphins and pilot whales. The tags are designed to relay information on dive duration, water temperature, dive depth and locations. This information is used to determine critical habitats for feeding, calving, breeding and migration.
Current research emphasizes Arctic to subtropical waters in the northern hemisphere.
