Abstract
 Passively Recorded Acoustic Data as a Component of Marine GIS Track: Ocean, Coastal, and Marine Resources Author(s): Heidi Batchelor, Gerald D'Spain Animals in the sea use sound for sensing their surroundings. Therefore, passively recorded acoustic data, incorporated into a marine GIS, provides critical information for understanding ocean habitat characteristics and for describing the acoustic interactions between marine organisms and their environment. This information is particularly important for evaluating the potential impacts of man-made sound sources in the marine environment. Specialized acoustic arrays and AUVs, in concert with advanced signal and array processing techniques, allow researchers and managers to passively record sound in the ocean and determine the locations of specific sound sources as a function of time and recording position. Acoustic data layers can be used for habitat classification, monitoring, behavioral studies, and for identifying areas of potential impacts to the marine environment from anthropogenic sources of ocean noise. An example utilizing acoustic data as a component of a marine geodatabase for a Southern California rockfish habitat will be presented.
