Rough-Toothed Dolphin Tracking

Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. From photo-identification and genetics there is evidence of an island-associated population of rough-toothed dolphins off Hawaiʻi Island (Big Island) that is isolated from the population off Kauaʻi. Satellite tagging has been undertaken off Kauaʻi to examine movements of individuals in relation to the Navy's Pacific Missile Range Facility. This research is ongoing.
