    Abstract: The Arctic is a sensitive acoustical environment due to a combination of very limited anthropogenic sound in the ice-covered winter, and because marine animals have evolved to use sound as their primary observing modality in the dark winter. With climate change induced reduction in ocean sea ice extent it is expected that surface ship traffic will increase. To evaluate the impact of increased shipping, a set of models have been developed by Applied Ocean Sciences to predict the shipping and wind/ice generated noise to help inform policy decision makers on options for maintaining a healthy and prestine environment for many endangered species. In this work we will present under ice propagation modeling approaches, a shipping model and a comparison between modeled shipping levels and estimated ambient (wind) noise levels.
