Wave-Ice-Ocean Interactions: Measurements, Modelling and Generated Acoustic Noise
Abstract
Wave-ice-ocean interactions will be investigated by experimental means in theMarginal Ice Zone (MIZ) of Antarctic, and numerically, by implementing the resultsin the wave-forecast model WAVEWATCH-III coupled with the ocean circulationmodel MOM5. It is well-known that the wave-ice-ocean interactions consist of anumber of complex inter-related phenomena with the critical unknown process amongthem being the wave-ice breakup. This breakup will be deduced in non-dimensionaluniversal terms, involving characteristics of wave field and material properties of ice,with account for ice fatigue subject to cyclic wave load. A set of targetedmeasurements will be conducted by employing buoys (loggers) developed at TheUniversity of Melbourne, with the use of vibration and acoustic sensors to detectmicro-cracking (fatigue) and major cracking (breakup). Apart from the wave-iceoceancoupling, attempts will be made to link the ice-breakup acoustic signals,through the Southern Ocean sound channel, with the low-frequency ocean noise alongthe Australian coast.Rationale and significance.
