The Arctic Ocean is (currently) a remarkably quiet place, as the presence of sea-ice isolates the ocean from the mixing effects of wind.  In this interdisciplinary project, we examine how the upper Arctic may change if sea-ice retreat increases.  We use observations and models to study Arctic mixed layer depths, internal wave energy, and the mixing of nutrients into the photic zone, with particular interest on  impacts on Arctic ecosystems.

Atlantic Waters (AWs) are volumetrically the largest inflow to the Arctic Ocean.  They form the major subsurface circum-arctic oceanic transport system, and are the greatest pan-arctic reservoir of oceanic heat. This project draws on a variety of observational data to study flow pathways,  fundamental properties and change in the Atlantic waters in the western Arctic.

The Bering Strait is the only Pacific gateway to the Arctic Ocean. Waters flowing through the strait are a key source of nutrients, heat and freshwater for the Arctic. Since 1990, APL-UW has measured the properties of this throughflow using long-term in situ moorings, supported by annual cruises. Project details, data, cruise reports and papers are available on the project web site.

The Bering Sea – lying at the northern end of the Pacific Ocean and north of the Aleutian Chain – is the source of over 50% of the total US fish catch and the home to immense populations of birds and marine mammals. This project uses a state-of-the-art numerical ocean-ice model to investigate prior (and predict future) changes in the Bering Sea ice cover and study the impacts of these changes on Bering Sea marine and eco-systems.

Our overarching goals are to study and understand the physical processes in the high latitude oceans, including large-scale circulation, shelf-basin interactions, and water mass formation; linkages between polar oceans and the lower latitudes; and the role of polar processes in climate. We do this primarily with observations, drawing on theory and modelling results to explain processes we observe. Our primary tools are subsurface moorings in ice-covered waters, which we deploy in several regions to study different questions.
