Ocean Acoustics (Code 322OA) Experimental Support Services for ONR's Ocean Battlespace Sensing Division

摘要

The collection of in-situ underwater acoustic and oceanographic data is critical to achieving a more complete understanding of how marine environmental conditions affect underwater acoustic transmissions, especially over vast ocean expanses. At-sea experiments provide the requisite data and performance measurements that are essential to developing and improving underwater sound detection systems, improving sound propagation and other models, and accurately characterizing the ambient underwater acoustic environment over annual cycles and differing spatial scales. Prior to at-sea experiments that involve underwater active acoustic transmissions, a thorough analysis of potential impacts on the marine environment associated with the transmission of anthropogenic sound is required by Federal legislative and regulatory dictates. Marine Acoustics, Inc. (MAI) provides the Ocean Acoustics department with the analytical rigor needed to ascertain potential environmental impacts associated with ONR Code 322OA-sponsored at-sea experiments. This impact analysis supports the comprehensive documentation required to verify compliance with the pertinent Federal and Navy requirements.
