Kaua‘i field project - August 2026
August 25, 2026
Researchers from Cascadia Research Collective are conducting a 9-day field session off Kaua'i to deploy LIMPET satellite tags on odontocete cetaceans prior to a Submarine Command Course (SCC) to be able to examine their behavior before, during, and after the training event.

First CEE Trial of 2026 – and False Killer Whales
July 23, 2026
The Atlantic BRS team had an extremely productive day on Friday, July 17th with tags deployed on both false killer whales and goose-beaked whales, as well as a successful controlled exposure experiment with simulated Continuous Active Sonar signals.
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).

Current
Visual Survey and Tagging of Hawaiian Odontocetes
Project Objectives
(1) define the spatial movement and habitat use patterns of species that are exposed to mid-frequency active (MFA) sonar (2) determine how these patterns influence exposure and potential responses
Complete
Conservation Canine for Marine Mammal Scat Collection in Hawaii
Project Objectives
Test whether a K9 can be trained to detect and 'direct' boat drivers via changes in behavior to the scat of marine mammals in Hawaii
Complete
Accelerometry Tag Development
Project Objectives
Increase capacity and develop training for marine mammal monitoring in Hawaii utilizing non-invasive triaxial accelerometry biologging tags to quantify fine-scale behavioral and energetic responses of protected species to potential anthropogenic disturbance
Complete
Small vessel visual surveys in the Mariana Islands Range Complex
Project Objectives
Identify species of beaked whales, odontocetes, and baleen whales that occur in the Mariana Islands; Monitor marine mammal and sea turtle presence, distribution, and diversity in nearshore waters during key seasons (summer and winter); Develop a better understanding of marine mammal distribution, movement patterns, habitat use, population structure, and abundance; Develop reference library of visually-validated acoustic recordings of marine mammals.
Current
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?
Current
Pacific Islands Comprehensive Stranding Investigations
Project Objectives
Conduct comprehensive investigations of stranded marine mammals throughout the Pacific Islands with emphasis on the Hawaiian and Mariana Island chains. This includes conducting necropsies of stranded animals, collecting and archiving samples, conducting disease screening, genetic testing, and analysis of historical data. The objective is to examine stranding patterns and causes of death for marine mammals in the Pacific Islands.No related documents to display
