The physical oceanography of waters under the North Water Polynya /
The North Water (NOW) is one of the largest polynyas in the Northern Hemisphere, occupying Smith Sound and the northern part of Baffin Bay, between Greenland and Ellesmere Island. While it has long been held that the North Water maintains itself by a southward drift of ice caused by winds and curren...
