ACOUSArctic Climate Observations Using Underwater Sound

In the ACOUS experiment in 1998-99, transmissions from a source deployed in Franz Victoria Strait to receivers in the Lincoln Sea and the Chukchi Sea measured continued basin-scale warming of the AIW and detected a rapid warming in a broadly dispersed mass of Atlantic water with a maximum temperature that exceeded 2.
The ACOUS experiment also showed that the received acoustic energy was correlated with path-average ice thickness changes, which could provide means for continuous remote observation of basin-scale changes in the average Arctic sea ice thickness (Gavrilov and Mikhalevsky, 2006).
The roughness of the ice is directly proportional to the thickness; thus, the thinner ice in the current Arctic is expected to reduce the propagation loss at higher frequencies, permitting use of higher-frequency sources that would be smaller and less costly than the 20 Hz sources used in the TAP and ACOUS experiments (Mikhalevsky, 2011).
