Description
Summary:The underwater acoustical detection of sperm whales and the estimation of their population density in the ocean environment is simulated using QBASIC program code. The program is designed to imitate the known behavior of sperm whales and the randomness of the natural environment encountered in the field. A ship-towed linear hydrophone array is modeled for detection of the whales. The program uses the basic theory of line transect sampling. The program can be run in either two-dimensions or three dimensions and is intended to be used in comparison and testing of two- and three-dimensional line transect theory.
