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

Project Objectives

Determine what species of marine mammals, specifically beaked whales, are present in the Marianas and examine their spatial and temporal patterns of acoustic behavior. Calculate acoustic abundance and density of beaked whales in surveyed area. Analyze sonar detections in area.

Project Objectives

Investigate potential impacts of naval activities on Hawaiian monk seals

Project Objectives

This 12‑month integrated pilot project combines three complementary components: (A) shore‑based theodolite monitoring of harbor porpoises, (B) high‑bandwidth passive acoustic monitoring and soundscape characterization, and (C) suction‑cup multi‑sensor tag deployments on Bigg’s (transient) killer whales. 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.

Project Objectives

Determine what species of marine mammals and sea turtles are present and estimate abundance.

Project Objectives

Improve understanding of the long term trends in occurrence of marine mammals on the PMRF and SOAR ranges.

Project Objectives

Determine the occurrence, movement patterns, and residency patterns of multiple humpback whale Distinct Population Segments within Pacific Ocean Navy Range Complexes

Project Objectives

Determine the movement patterns, occurrence, and residence times of blue whales and fin whales within U.S. Navy training and testing areas as well as Biologically Important Areas along the U.S. West Coast

Project Objectives

Improve understanding of the long term trends in occurrence of marine mammals (e.g., minke, humpback, fin, Bryde's, Blainville's) on the PMRF range. Examine what, if any, acoustic and physical behavioral responses occur to Navy activities.

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.
