Sea ice physical processes and biological linkages within the North Water polynya during 1998
Sea ice is a major component of the Earth's climate system and is believed to be a sensitive indicator of climate change. The North Water (NOW) refers to a region of anomalous sea ice conditions at the northern end of Baffin Bay. The dynamic sea ice cover is due to the presence of the NOW polyn...
