Global Warming and Sea Ice by Northern Canada

69.9N 120.1W

June 13th, 2013 Category: Climate Change MODISTerra

Canada – June 12th, 2013

Bodies of water in the Arctic, in Canada’s Northwest Territories and the province of Nunavut are covered in ice: the Great Bear Lake (below), Amundsen Gulf (upper left) and Queen Maud Gulf (upper right). Most of the sea ice breaks up in July during a normal year, with some areas only breaking up in August. Here, ice can be seen breaking up in Amundsen Gulf, near the left edge.

Ongoing changes in the climate of the Arctic include rising temperatures, loss of sea ice, and melting of the Greenland ice sheet. The Arctic ocean will likely be free of summer sea ice before the year 2100. Because of the amplified response of the Arctic to global warming, it is often seen as a high-sensitivity indicator of climate change.

Canada – September 3rd, 2012

Foxe Basin is a shallow oceanic basin north of Hudson Bay, in Nunavut, Canada, located between Baffin Island and the Melville Peninsula. For most of the year, it is blocked by ice floes. Here, however, the basin appears mostly ice-free, and sediments can be seen along the shores and phytoplankton are visible in the waters, whose nutrient-rich cold waters are known to be especially favorable to such blooms.

The largest island visible in the basin is Prince Charles Island, with an area of 9,521 km2 (3,676 sq mi). Visible north of the island by the top edge is the bright white Barnes Ice Cap, an ice cap located in central Baffin Island, Nunavut. It covers close to 6000 km2 and has been thinning due to regional warming. Between 2004 and 2006, the ice cap was thinning at a rate of 1 m per year.

Smoke Over Belcher Islands and Hudson Bay, Canada

Canada – July 13th, 2012

A veil of smoke hangs over Hudson Bay, Canada, and the Belcher Islands (below center). The Belcher Islands are an archipelago in Qikiqtaaluk Region, Nunavut, Canada. Located in Hudson Bay, the Belcher Islands are spread out over almost 3000 km2. The smoke is probably blowing northward from fires near the border between the provinces of Manitoba and Saskatchewan (click here for more images).

Greenish Waters of Larsen Sound, Canada

Canada - July 24th, 2011

The greenish body of water in the lower part of this image is Larsen Sound, an Arctic waterway in Kitikmeot Region, Nunavut, Canada. It is located south of Prince of Wales Island, west of the Boothia Peninsula, north of King William Island and east of Gateshead Island. To the west and north-west the sound opens into the M’Clintock Channel, to the north-east it opens into Peel Sound, to the south-east into James Ross Strait, and to the south-west into Victoria Strait.

In the full image, the Gulf of Boothia can be seen to the east, also greenish in color. Also in Nunavut, Canada, the western side is within Kitikmeot Region while the eastern side is in Qikiqtaaluk Region. It is situated between Baffin Island and the Boothia Peninsula. It is bounded by the Melville Peninsula and the Canadian mainland to the south; to the north it leads into Prince Regent Inlet and Lancaster Sound.

Ice and Sediments in Foxe Basin, Canada

Canada - July 24th, 2011

Foxe Basin is a shallow oceanic basin north of Hudson Bay, in Nunavut, Canada, located between Baffin Island and the Melville Peninsula. For most of the year, it is blocked by ice floes. In this summer image, some ice can be seen in the northern part of the basin, although the southern part is ice-free.

In the full image, sediments can be seen framing the shores of the islands in the bay, particularly Prince Charles Island (just above center). It is a large, low-lying island with an area of 9521 km2, off the west coast of Baffin Island, in the Qikiqtaaluk Region of Nunavut, Canada. The island is uninhabited and its temperatures are extremely cold.
