| description | This work investigates the underwater noise propagation of the primary vessel used by the Australian Antarctic Division Aurora Australis while stationary in a configuration and location suitable for under-ice Autonomous Underwater Vehicle (AUV) deployment. It outlines a novel method for recording and validating the noise of a vessel using available equipment and standard deployment options. Numerical modelling using the Fast Multipole Boundary Element Method (FMBEM) is combined with the response to a calibrated source to assess the limitations and residual uncertainty of the experiment. The results of this work indicate that there is a 10 dB re View the MathML source1µPa reduction in mean noise by removal of main engine noise and a low point in ship noise at 3.8 kHz. Two hundred metres depth was found to be a preferred depth for uniformity in the noise field. |
