Underwater acoustic propagation model

Keacoustics performed an acoustic impact study produced by the oceanographic survey and research vessel of the Spanish National Research Council (CSIC) called the “Sarmiento de Gamboa” in a geophysical experiment of the Aegean Sea.

Based on the input data from the different configurations of the vessel’s air guns, velocity profile and geographical data, a geophysical model was created, which was used to simulate the propagation of underwater acoustic waves caused by the vessel’s air guns.

Thanks to computer simulations developed my Keacoustics using different propagation models, the exclusion distances are determined: distances from the vessel where no marine mammals should be present during the campaign. Working closely with Submon, the exclusion distances for each species of marine mammal present in the area were determined.
