Arctic Archipelago Disagreement over the passages' status has raised Canadian concerns about environmental enforcement, national security, and general sovereignty. Hans Island, in the Nares Strait east of Ellesmere Island, is a territory currently contested between Canada and Denmark. The archipelago extends some longitudinally and from the mainland to Cape Columbia, the northernmost point on Ellesmere Island. It is bounded on the west by the Beaufort Sea; on the northwest by the Arctic Ocean; on the east by Greenland, Baffin Bay and Davis Strait; and on the south by Hudson Bay and the Canadian mainland. The various islands are separated from each other
Cook Strait west side and North Island on the east. At its narrowest point, separate Cape Terawhiti in the North Island from Perano Head on Arapaoa Island in the Marlborough Sounds. Perano Head is actually further north than Cape Terawhiti. In good weather one can see clearly across the strait. The west (South Island) coast runs along Cloudy Bay and past the islands and entrances to the Marlborough Sounds. The east (North Island) coast runs along Palliser Bay, crosses the entrance to Wellington harbour, past some Wellington suburbs and continues another to Makara beach.
