Mitigation Modelling of the Leeuwin Class Hydrographic Sonars in Jervis Bay

Abstract

Jervis Bay is an important training area for the Royal Australian Navy. To conduct operations in Jervis Bay in an environmentally sensitive manner Navy use mitigation strategies during any training exercises. One such mitigation strategy is to have established stand-off ranges, and to cease sonar operations when a marine mammal is within these ranges. This document describes an improved determination of these stand-off ranges based on the effect of acoustic energy emanating from the Leeuwin class hydrographic ship sonars. Modelling methods used and the mitigation ranges calculated are shown.
