Marine Species Monitoring

Pacific Marine Assessment Program for Protected Species (PACMAPPS) survey

Introduction & Objectives

The Navy continued its ongoing collaboration with NOAA called PacMAPPS (Pacific Marine Assessment Program for Protected Species) by providing significant funding toward the second systematic line transect survey of the Mariana Islands.  This survey occurred in May-July 2021 in order to increase knowledge of marine mammal occurrence, density, and population identity in MITT.  This survey will complement the data obtained during small boat surveys funded jointly by the Navy and NOAA from 2010-2019. It will also complement the Navy-contracted 2007 MISTCS survey that provided the first marine mammal density estimates for the Marianas.  The survey results are expected to result in density estimates, which will be used by the Navy and NOAA for stock assessment reports (NOAA) and effects modeling (Navy).

The Navy continued the collaboration for a systematic line transect survey of the Gulf of Alaska in summer 2022. This survey will increase knowledge of marine mammal occurrence, density, and population identity in the Gulf of Alaska Temporary Maritime Activities Area (GOA TMAA). 

Previous PacMAPPS surveys occurred in the Hawaiian Archipelago during summer 2017 and winter 2020 and along the U.S. west coast from California to Washington during 2018 with the same objectives to increase knowledge of marine mammal occurrence, density, and population identity.  The survey results resulted in density estimates used by the Navy and NOAA for stock assessment reports and effects modeling. 

Technical Approach

Large ship systematic line transect surveys, incorporating the following data collection methods: visual survey, photo-identification, biopsy and genetic analysis, satellite tagging, opportunistic acoustic recording
