Development and testing of two towed volumetric hydrophone array prototypes to improve localization accuracy during shipboard line-transect cetacean surveys

The following document presents the result of a project aimed at improving the hydrodynamics of the volumetric array design for towing at faster speeds of 10 knots from large research vessels. The document explains the theory behind the design considerations for each prototype presented, sea trial results and subsequent modifications, and discuss improvements for future...
