As more human activity enters the Arctic, it is important to be able to detect and classify the resulting impact from human behaviors. Examples of anthropogenic impact sources might include shipping through the Northwest Passage, natural resource exploration, and tourism.

A simple way to measure this impact is to use a sparse array of acoustic and seismic sensors. In order to do that, we need to understand the propagation of acoustic energy through and between the ice, air, and water domains. With this work we begin to understand the energy propagation, which will guide us in designing and building future sensing systems in the evolving Arctic.
