Description
Summary:The impact of anthropogenic sound on the marine ecosystem has become an area of concern and subsequently increased research. As part of the Atlantic Deep Water Ecosystem Observatory Network (ADEON, adeon.unh.edu), a five-year collection effort of acoustic, oceanographic, marine ecosystem, and remote sensing satellite observations is underway. The centerpiece of the network is 6 long-term landers deployed off the coast of Jacksonville up past the mouth of the Chesapeake Bay. In this paper we present results from the first (of four) horizontal line array measurement cruises (deployed from a sailboat) between two of the moorings. The scientific objective is to evaluate the horizontal directionality of the ambient sound field and to measure the spatial correlation of the noise between the lander off of Wilmington NC and the lander off of the Virginia. A soundscape model, including environmental and source level variability will be presented. The acoustic sources will include ships, wind, rain, and marine mammals.
