Nares Strait (Template:Lang-da; Template:Lang-fr) is a waterway between Ellesmere Island and Greenland that connects the northern part of Baffin Bay in the Atlantic Ocean with the Lincoln Sea in the Arctic Ocean. From south to north, the strait includes Smith Sound, Kane Basin, Kennedy Channel, Hall Basin and Robeson Channel. During 1962–64, a 20 km (12 mi) by 10 km (6.2 mi) ice island drifted southward from the Lincoln Sea through the Nares and Davis Straits to the Atlantic Ocean (Labrador Sea).[1] Nares strait has a nearly permanent current from the north, powered by the Beaufort Gyre, making it harder to traverse for ships coming from the south.
In 1964, its name was agreed by the Danish (Stednavneudvalget, now Stednavnenævnet) and Canadian governments. The name derives from the British naval officer George Strong Nares.
The strait and neighbouring waters are usually hazardous for navigation and shipping. During August, however, it is usually navigable by icebreakers. Prior to 1948, only five vessels were recorded as having successfully navigated north of Kane Basin. In 2009 the ship Arctic Sunrise made the first known June transit into the Arctic Ocean.[2]
Hans Island, a tiny island lying within the strait, is claimed by both Denmark (on behalf of Greenland) and Canada. Other islands within the strait are Joe Island, Crozier Island, and the much larger Franklin Island.
Thule People reached the Nares Strait in the early 13th century, where they hunted with and traded with Vikings.[3] Archeological remains of Thule Culture and Viking presence are found on Ruin Island.
