Development and validation of methodologies underwater acoustics for remote observation of air-sea-ice interaction processes in polynya areas

Objective of the project is to develop and test acoustic methodologies for the long-term monitoring of environmental variability in the Antarctic regions, through underwater acoustic oceanography experiments. Using passive and active acoustic systems is possible obtain the remote observation of air-sea-ice interaction processes in polynya areas in the Terra Nova Bay (74 ° 40′59.99 "S 164 ° 04′00.01" E). Acoustic measurements are carryed out by launching an oceanographic mooring supporting a 300 kHz broadband ADCP and CTD probes (temperature, conductivity and pressure sensors), left in the area until the following year's campaign.
