The Copernicus Sentinel-3 mission takes us over a part of the Canadian Arctic Archipelago. Many of the archipelago is a part of Nunavut – the most important and northernmost territory of Canada.
The archipelago covers an space of round 1,500,000 sq km and consists of 94 main islands and greater than 36,000 minor ones. The archipelago is sure by the Beaufort Sea to the west and by Hudson Bay and the Canadian mainland to the south – largely obscured by clouds on this picture.
The varied islands of the Canadian Arctic Archipelago are separated by a collection of waterways collectively referred to as the Northwest Passage. Previously, the Northwest Passage has been impassable owing to its thick, year-round sea ice.
Nevertheless, owing to important adjustments within the Arctic local weather, summer time sea ice has decreased considerably and has led to an rising variety of vessels navigating by means of this once-impossible route.
On this picture, captured on July 27, 2019, sea ice may be seen within the waterways of the Canadian Archipelago, in addition to broken-up sea ice within the Beaufort Sea. Quite a few, giant ice floes are seen on the southern margin of the pack ice, and may be seen drifting southwards. Because the pack ice drifts and encounters hotter waters, the ice is extra susceptible to speedy melting.
In accordance with the Nationwide Snow and Ice Knowledge Middle (NSIDC), the ocean ice extent in July 2019 declined at a mean each day fee of 105 700 sq km – exceeding the 1981 to 2010 common fee of 86 800 sq km per day.
This picture was captured within the days when a number of wildfires had been burning within the Arctic, particularly Siberia. On this picture, a wildfire may be seen on mainland Canada, alongside the Mackenzie River, and smoke plumes are seen blowing westwards.
Banks Island – the westernmost island of the Arctic Archipelago – is seen within the middle of the picture. The island has a big inhabitants of Arctic foxes, in addition to caribou, polar bears and wolves. Numerous glacial lakes may be seen in emerald inexperienced on the east facet of the island.
Victoria Island lies to the east of Banks Island, and may be recognized with its deeply indented coast. With an space of round 200 000 sq km, Victoria Island is barely slighter smaller than the island of Nice Britain.
