Using DTAGs to study acoustics and behavior of Southern Resident killer whales
Cascadia Research is collaborating with researchers from the NOAA Fisheries Northwest Fisheries Science Center (NWFSC) on a study using digital acoustic recording tags (DTAGs) to examine sound exposure, sound use and behavior.
Several risk factors were identified as part of the ESA listing process for Southern Resident killer whales (SRKWs), and were included in the recovery plan. These include prey quality and quantity, water pollution and environmental contaminants, vessel effects and sound exposure, and cumulative effects. A number of scientific studies conducted over the past several years have investigated foraging and dive behavior, behavioral responses to vessels and anthropogenic noise exposure in Southern Residents. All of these studies have provided important scientific information that has helped guide recovery efforts and other management decisions of endangered SR killer whales.
