Kaua'i Field Work Updates
February 20, 2025
Scientists from Cascadia Research Collective recently completed a ~9-day field project off Kaua’i that started on February 9th. This project is timed to occur prior to a Submarine Command Course (SCC) training event. The primary goal is to deploy satellite telemetry tags on multiple species of odontocete cetaceans prior to the SCC, to be able to examine their behavior before, during, and after the event. This approach has been very successful in the past as a way of examining how different species respond to Navy training activities including mid-frequency active sonar (MFAS).

Estimation of Received Levels of MFAS and Behavioral Response of Marine Mammals at PMRF
Project Objectives
Further our understanding of the Monitoring Questions: 1) What is the occurrence and estimated received levels of MFAS on 'blackfish', humpback, minke, sperm and Blainville's beaked whales within the PMRF instrumented range? and 2) What, if any, are the short term behavioral responses of 'blackfish,' humpback, minke, sperm and Blainville's beaked whales when exposed to MFAS/explosions at different levels/conditions at PMRF?

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.
