Arctic Meteorology and Oceanography

arctic Nares Strait, a narrow channel between Ellesmere Island and Greenland, is an important conduit for the exchange of ice and freshwater between the Arctic Ocean and the North Atlantic Ocean. Nares Strait connects the Lincoln Sea in the north to Baffin Bay in the south, and includes Robeson Channel, Hall Basin, Kennedy Channel, Kane Basin, and Smith Sound. At 500 km long and nominally 35 km wide, with channel walls of 500-2000 m, it may also be the largest natural wind "tunnel" in the world. With colleagues at CEOAS and elsewhere, I am investigating the meteorology and oceanography of this harsh but spectacularly beautiful region.
