Together, these data streams will quantify occurrence, movement, diving, and behavioral context for these two key species in relation to the local soundscape—including operational signals near the Dabob Bay Range Complex (DBRC) and the Bangor Trident Base. Results can provide an empirical foundation and inform the study design of future cetacean behavioral response studies (BRS) in Hood Canal.

With acoustic telemetry, determine 1) the location of green sturgeon detections within Washington, 2) the season for specific habitat use (e.g., estuaries; coastal waters), 3) the frequency an animal moves between coastal and estuarine waters, and 4) the range of each tagged animal.

Telemetry and Genetic Identity of Chinook Salmon in Alaska
Project Objectives
To use a combination of pop-up satellite technology and salmon genetics to provide critical information on Chinook salmon spatial and temporal distribution in the Gulf of Alaska and along the Washington coast to inform salmon management and U.S. Navy training activities. The study seeks to 1) determine the occurrence, timing, and specific run of Chinook salmon through genetics within the Navy training areas; 2) describe the influence of environmental covariates on Chinook salmon occurrence; and 3) improve the understanding of run-specific timing and geographical occurrence of Chinook salmon as the prey of Southern Resident killer whales in Washington.

Characterizing the Distribution of ESA-listed Salmonids in Washington and Alaska
Project Objectives
Use acoustic tagging technology to provide critical information on spatial and temporal distribution of salmonids to inform salmon management, U.S. Navy activity, and Southern Resident Killer Whale (SRKW) conservation. The study seeks to 1) determine the occurrence and timing of salmonids within the Navy training ranges, 2) describe the influence of environmental covariates on salmonid occurrence; and, 3) describe the occurrence of salmonids in relation to SRKW distribution.

Acoustic and Visual Survey for Cetaceans in Behm Canal and Southern Clarence Strait, Alaska
Project Objectives
Conduct visual line-transect surveys and passive acoustic monitoring for cetaceans, and other marine mammals, to determine species occurrence, and to estimate density within Navy’s testing range. Acoustic monitoring devices will be deployed during the vessel based survey, and long-term passive acoustic hydrophones will be monitored for year-round detection of rare and/or cryptic cetacean species.
