The Bering Strait is the only oceanic gateway between the Pacific and the Arctic.  The flow through the strait dominates the waters of the Chukchi Sea; brings nutrients, heat and freshwater into the Arctic (vital for Arctic ecosystems); and (models suggest) influences the deep circulation of the Atlantic (with implications for global climate).   Since 1990, we have placed year-round moorings in the Bering Strait to measure the volume and water properties of the throughflow.  Using these data and hydrographic data from ship surveys, we try and understand how the throughflow is changing and why.
