Ammarqua Strait Ammarqua Strait Ammarqua Strait (old spelling: "Angmarqua") is a strait in the southern part of the Upernavik Archipelago in the Qaasuitsup municipality in northwestern Greenland. The strait separates Nutaarmiut Island from four large islands in the east, Uilortussoq Island and Saninngassoq Island in the north; Nako Island and Akuliaruseq Island in the south. The Eqalugaarsuit Suulluat Fjord opens into Ammarqua Strait immediately to the east of the southern cape, to the north of Kangeq Peninsula off the mainland of Greenland. At the southern mouth of the strait at the confluence with Baffin Bay are two islands: the Ineraq Island and
Baffin Island at a similar latitude. Sea ice surrounds the island for most of the year, and only disappears completely from the north coast for short unpredictable periods from mid- to late June until the end of September. Most of Baffin Island lies above the Arctic Circle and all the communities from Pangnirtung northwards have polar night in winter and the midnight sun in summer. The eastern community of Clyde River has twilight instead of night from April 26 until May 13, continuous sunlight for 2½ months from May 14 to July 28, then twilight instead of night from July 29 until
