摘要
Shallow water experiments have been conducted in Nantucket Sound with an autonomous underwater vehicle towed hydrophone array system in an area proximate to that of a previous experiment [Frisk and Lynch, J. Acoust. Soc. Am. 86, 1928-1939 (1989)]. Transmission loss was measured, for frequencies between 220 and 1228 Hz in an ocean waveguide, under conditions of an isovelocity water column with an approximate depth of 13 m over a sandy-silty bottom. Results obtained at 415 Hz show classic isovelocity waveguide phenomena that include interference effects, mode stripping due to modal attenuation, and transmission loss proportional 15 to 10 log(10)(R).
