SRKW acoustic response (Investigating noise effects on the acoustic signals and behavior of Southern Resident killer whales (Orcinus orca))

In this study, vocal compensation is being investigated in Southern Resident killer whale (SRKW) calls to determine the degree to which whales can adjust to increased background noise levels. In addition, whale and vessel behavior data are also collected to determine what contribution vessel traffic has on noise levels and how noise levels influence whale behavior. The work was part of an NRC-postdoctoral project led by Marla Holt, and includes Dawn Noren (Adams) and Candice Emmons as internal collaborators. The specific work includes experimental design, data collection, data analysis, and writing for submission to peer-reviewed journals. This is a one-time project, and addresses key risk factors (vessel and noise interactions) of SRKW. Measurements of vocal behavior, whale behavioral states, background noise measurements, vessel counts and other attributes
