Project Objectives

Response

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

Obtain data to characterize the potential exposure of marine mammals and ESA-listed marine species to Navy training and testing activities, evaluate the effectiveness of mitigation measures

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?

Project Objectives

Improve knowledge of baseline population demographics, vital rates, and movement patterns of Cuvier’s beaked whales and fin whales. Examine what, if any, short term behavioral and/or vocal responses occur when exposed to sonar or explosions at different levels and conditions. Determine if exposure to sonar or explosives impact the long term fitness and survival of individuals or the population, species, or stock

Project Objectives

Assess availability bias and habitat associations of endangered Kemp’s ridley and threatened green sea turtles to improve spatial density models

Project Objectives

Monitor species composition and distribution on JSWTR, support M3R species verifications

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

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

Project Objectives

Assess occurrence, habitat use, and baseline behavior of humpback whales in the mid-Atlantic region

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

Project Objectives

Establish behavioral baseline and foraging ecology. Assess behavioral response to acoustic stimuli and Navy training activities

Project Objectives

1) Identify and classify Southern Resident killer whale (SRKW) detections from acoustic recorders and satellite tag tracking; 2) Develop a model to estimate the seasonal and annual occurrence patterns of southern resident killer whales relative to offshore Navy training ranges. 3) Characterize occurrence of anthropogenic sounds in potential SRKW habitat. 4) Develop state space habitat model for SRKW prey, based on fall Chinook salmon tagged released from California to British Columbia between 1977 and 1990 to estimate seasonal distribution along the west coast.

Project Objectives

Project Objectives

The goal of the visual surveys is to collect individually-identifying information from humpback whales present near and around Farallon de Medinilla (FDM)

Project Objectives

To determine the abundance and habitat use of California sea lions that haul out at Navy facilities and forage in testing and training areas

Project Objectives

Develop a better understanding of sea turtle distribution and habitat use in the Mariana Islands, particularly in relation to locations used by the Navy for underwater detonation training

Project Objectives

Determine the source levels produced by impact and vibratory driving of different size and material piles during construction projects

Project Objectives

Determine the distribution and temporal patterns of beaked whale occurrence in the waters within and outside the Southern California Range Complex (SOCAL). Use passive acoustic monitoring to determine what species are present in SOCAL and examine spatial and temporal patterns.

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
