Atlantic Odontocete Movements and Behavior

Movements, behavior, and spatial use of odontocetes off the mid-Atlantic states

From 2014 through 2018 we were involved in a collaborative project with researchers from Duke University Marine Lab to examine movements and diving behavior of a number of species of odontocetes along the east coast of the U.S., using LIMPET satellite tags. Starting in 2017 this work expanded as part of a behavioral response study to examine how some species respond to mid-frequency active sonar, collaborating with researchers from Southall Environmental Associates and others. The primary study area is off Cape Hatteras, North Carolina, with additional field effort off Jacksonville, Florida. The two primary study species are Cuvier’s beaked whales and short-finned pilot whales, but we have also obtained movement information from common bottlenose dolphins (in 2014, 2015 and 2016), short-beaked common dolphins (in 2014 and 2016), an Atlantic spotted dolphin (in 2016), a Clymene dolphin (in 2016), a Risso’s dolphin (in 2016), and a sperm whale (in 2015). More details are available in the yearly reports below as well as a number of peer-reviewed publications that have come out on this work.

Cascadia biologists involved in this effort are Daniel Webster and Robin Baird. For more information on this work contact Robin Baird at rwbaird (at) cascadiaresearch.org

The tagging work was undertaken under NMFS scientific research permits No. 15330 and 20605, and was funded by the Naval Facilities Engineering Command Atlantic as part of the Navy’s marine species monitoring program
