Long Term Statistical Measurements of Environmental Acoustics Parameters in the Arctic. AEAS Report Number 1. Ambient Noise Levels in the West Greenland Sea.

Propagation loss data were taken using manned ice camps and aircraft and ambient noise levels were measured using arctic data buoys that operated through the NIMBUS 6 and NOAA series satellites. The present report addresses one of a total of six arctic geographic areas - the West Greenland Sea, and...

Description
Summary:Propagation loss data were taken using manned ice camps and aircraft and ambient noise levels were measured using arctic data buoys that operated through the NIMBUS 6 and NOAA series satellites. The present report addresses one of a total of six arctic geographic areas - the West Greenland Sea, and presents ambient noise levels taken every three hours at the synoptic weather times from nine data buoys that drifted through the area. These data buoys collect a very large amount of independent measurements that are impractical to present in raw form. Therefore, a first-level statistical analysis was performed to allow reporting and distribution. These data, along with other regularly available meteorological, oceanographic and ice data, should enable higher order analyses and modeling for both prediction and understanding the mechanisms of arctic background noise. The data buoys, while limited in some respects, offer the only present means of long-term, wide-area investigations of arctic ambient noise on a true statistical basis. See also AD-A156 576.
