Cascadia Research Collective (CRC) has been undertaking surveys for odontocetes in Hawaiian waters since 2000. From photo-identification and satellite tagging there is evidence of a small resident population of Blainville's beaked whales off the island of Hawaiʻi (Big Island), as well as an offshore population. Less is known about this species off other islands.
The MdTag009 tag deployment is an individual from the offshore population (Baird et al. 2011), while other deployments are on individuals from the resident insular population (Schorr et al. 2009).
