Population density of sperm whales in the Bahamas estimated using propagation modeling.

摘要: The population density of sperm whales is estimated using an acoustic model to calculate the probability receiving their clicks. uses estimates (1) source level clicks, (2) beampattern whales’ emitted (3) distribution whale orientations, (4) loss between and receiver (derived from propagation modeling), (5) noise levels at receiver, (6) detector’s rates missed calls false detections, (7) average click rate. These data are combined in a that propagates simulated clicks various positions hydrophone estimate detection function—the as function distance. This then with information on (performed chosen time day when appear measurably predictable rate) corresponding number received given peri...
