Overview

Passive Acoustic Monitoring is a proven means of detecting, classifying, and localizing vocally active marine mammals through the use of underwater microphones known as hydrophones. These sensors can be moored, drifted, towed or mounted on unmanned mobile platforms. The U.S. Navy has invested in the development and testing of these sensors on a variety of platforms in order to determine the advantages of each type. The images were collected as part of multiple U.S. Navy Living Marine Resources Program funded projects led by John Hildebrand (University of California San Diego), Haru Matsumoto (Oregon State University), Phil Abbot (OASIS, Inc.), and Sofie Van Parijs (NOAA Fisheries-Northeast Fisheries Science Center), which all build off of previous Office of Naval Research funded efforts.
