The minor sea located between Greenland and Canada is the Nares Strait. This body of water connects the Arctic and Atlantic oceans and plays a critical role in the maritime navigation of the region. The strait separates Greenland from Baffin Island in Canada and is significant for its ice flow and shipping routes. It is also an area of importance for various marine species and is affected by climate change, which alters the ice conditions and could impact the ecological balance within this sensitive environment.
