Pacific Monitoring Projects
The table below summarizes current marine species monitoring projects being conducted in the Pacific Ocean in support of Gulf of Alaska Navy Training Activities (GOA), Hawaii-Southern California Training & Testing (HSTT), Marianas Training and Testing (MITT), and Northwest Training and Testing (NWTT) Marine Mammal Protection Act requirements (50 CFR Part 218). Reports and data from these projects will be made available on the individual project profile pages and the Reading Room as they become available.

Title: Pacific Marine Assessment Program for Protected Species (PACMAPPS) survey
Location: Gulf of Alaska, Mariana Island archipelago, Hawaiian Islands archipelago, California-Oregon-Washington Objectives: Identify species of beaked whales, odontocetes, and baleen whales that occur in the surveyed areas; Monitor marine mammal and sea turtle presence, distribution, and diversity in offshore waters; 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. Methods: Visual surveys, photo-identification, biopsy and genetic analysis, satellite tagging, opportunistic acoustic recording during sightings Performing Organizations: National Marine Fisheries Service Pacific Islands Fisheries Science Center, National Marine Fisheries Service Southwest Fisheries Science Center, National Marine Fisheries Service Alaska Fisheries Science Center Timeline: 2017-2023 Funding: FY17 $183k; FY18 $164k+$265k+$200k; FY21 $300k; FY23 planned |

Title: Pacific Islands comprehensive stranding investigations
Location: Hawaii, Guam, CNMI 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.

Title: Estimation of Received Levels of MFAS and Behavioral Response of Marine Mammals at PMRF
Location: Hawaii 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? Methods: PAM, tagging, photo-ID, biopsy, visual survey Performing Organizations: Cascadia Research Collective, Naval Information Warfare Center Pacific (formerly SPAWAR Systems Center Pacific), Southall Environmental Associates, and HDR, Inc.
