Species Distribution: Rough-Toothed Dolphin - Hawaii

Metadata Updated: December 8, 2023

This dataset contains a collection of known point locations of rough-toothed dolphins identified either via automated satellite tracking of tagged organisms or through direct human observation via shipborne and aerial surveys. This can be useful for assessing species abundance, population structure, habitat use, and behavior. This collection is aggregated from multiple data sources and survey periods listed below. Each data point contains attributes for further information about the time and source of the observation. This dataset was compiled by the Pacific Islands Ocean Observing System (PacIOOS) and may be updated in the future if additional data sources are acquired.

Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. Rough-toothed dolphins are the most abundant odontocetes around the islands of Kauai and Niihau although uncommon elsewhere. There is a small resident population of this species off of Hawaii Island. Satellite tagging has been undertaken off Kauai to examine movements of individuals in relation to the U.S. Navy's Pacific Missile Range Facility. In addition, Dr. Joseph Mobley of the Marine Mammal Research Consultants (MMRC) led aerial surveys for cetaceans in Hawaiian waters from 1993-2003.
