Abstract:

The Arctic Ocean is undergoing dramatic changes in both the ice cover and ocean structure. Changes in sea ice and the water column affect both acoustic propagation and ambient noise. This implies that what was learned about Arctic acoustics during the Cold War is now obsolete. The goal of the Canada Basin Acoustic Propagation Experiment CANAPE is to determine the fundamental limits to the use of acoustic methods and signal processing imposed by ice and ocean processes in the new Arctic. The hope is that these first few new steps will lead to a larger, permanent acoustic monitoring, navigation, and communications network in the Arctic Ocean Mikhalevsky et al., 2015.
