SHALLOW-WATER ACOUSTIC GEOACOUSTIC EXPERIMENTS AT THE NEW-JERSEY ATLANTIC GENERATING-STATION SITE

Shallow-water acoustic experiments were conducted at the Atlantic Generating Station site on the New Jersey Continental Shelf as a part of a long-term study of the shallow-water physics in this region. A vertical hydrophone array and an airgun were used to assess the dispersion characteristics of the broadband acoustic field. A geoacoustic data set including bottom impedance profiles were constructed based on previous measurements of geological parameters from sediment core data. Experimental results show that the acoustic wave-field dispersion is dependent on the azimuth angle. This dependency may be attributed to several factors relating to topography, range, and depth features. © 1994, Acoustical Society of America. All rights reserved.
