Mariana Islands Marine Resource Survey (MIMRS)

Goal: To collect data on the occurrence of marine mammals around Pagan Island to provide information for the U.S. Military's Environmental Impact Statement (EIS) related to the expansion of the Mariana Islands Testing and Training (MITT) site.

Time Period: 2013

Our Role: To design and implement the passive acoustic monitoring components of the survey. To analyze all passive acoustic data and assist in the completion of a final report to be used in support of the Draft and Final EIS.

Synopsis:
In the summer of 2013 Bio-Waves, Inc. participated in an expedition to gather biological and acoustic data on marine mammals around the remote island of Pagan, located in the northern part of the Northern Mariana Islands. The goal of the survey was to assess the occurrence and distribution marine mammal populations in the study area and provide data for an Environmental Impact Statement related to the planned expansion of the U.S. Military's Mariana Islands Testing and Training (MITT) site. Bio-Waves collected passive acoustic data on marine mammals around the islands of Pagan, Tinian and Saipan (with a focus on Pagan). The Bio-Waves research team spent approximately two weeks in this remote region conducting towed hydrophone array surveys, deploying sonobuoys and conducting work from small inflatable boats, in the near-shore (3 nmi from shore) environment. We have competed analysis of the data collected and a final report is being produced. The results of these efforts will be integrated into the U.S. Military's final EIS, which soon will be made available to the public.

Partners: AECOM (Prime), Tetra Tech. Inc., Clymene Enterprises, and numerous independent marine scientists.
