PARKA II-A Bottom Loss Measurements

Abstract

Bottom Loss Measurements were conducted during the PARKA II-A experiment in the vicinity occupied by R/V FLIP for the main propagation loss measurements. The objective was to obtain low frequency (100-1000 Hz) bottom loss values for use in models for predicting propagation loss. The location is approximately 300 miles north of the Hawaiian Islands. Data was obtained as a function of grazing angle and frequency. A single hydrophone was suspended at a depth of 11000 ft below the USNS SANDS while the R/V CONRAD detonated explosives at depths of 500 and 11000 ft as range was varied. Because of the location for the measurements these results are compared to MGS AREA-V GROUP-V low frequency results. (Author)
