Canada – May 25th, 2013

Sediments can be seen between the southern shores of Akimiski Island and mainland Ontario, Canada. It is the largest island in James Bay, a southeasterly extension of Hudson Bay.

Scientists have found evidence of warming in western Hudson Bay and cooling in the east, and of earlier ice-breakup at lakes southwest of Hudson Bay. They also presented evidence of increasing annual precipitation with trends toward greater precipitation in spring, summer, and autumn (click here for more information).

Canada – March 23rd, 2013

Hudson Bay is a large body of saltwater in northeastern Canada. It drains a very large area, about 3,861,400 square kilometres (1,490,900 sq mi), that includes parts of Ontario, Quebec, Saskatchewan, Alberta, most of Manitoba, southeastern Nunavut, as well as parts of North Dakota, South Dakota, Minnesota, and Montana. The southern arm of Hudson Bay is called James Bay (visible in the full image).

Here, ice can be seen breaking near the eastern shoreline of Hudson Bay. Sea ice studies consider Hudson Bay part of Arctic Sea. In March, Arctic sea ice is nearing its winter maximum and will soon begin its seasonal decline. This year, ice extent remains below average, in part a result of the persistence of the negative phase of the Arctic Oscillation that has kept winter temperatures warmer than average.

Average sea ice extent for February 2013 was 14.66 million square kilometers (5.66 million square miles). This is 980,000 square kilometers (378,000 square miles) below the 1979 to 2000 average for the month, and is the seventh-lowest February extent in the satellite record. Since 2004, the February average extent has remained below 15 million square kilometers (5.79 million square miles) every year except 2008. Prior to 2004, February average extent had never been less than 15 million square kilometers. Ice extent remains slightly below average everywhere except the Bering Sea.

Ice Around Akimiski Island in James Bay, Canada

Canada – January 26th, 2013

James Bay, a southeasterly extension of Hudson Bay, in Canada, appears covered in ice in this winter image. The surrounding land and Akimiski Island (near the western shores of the bay), the largest island in the bay and an important coastal wetland and waterfowl habitat, are covered in snow. Several rivers can be seen through the snow, flowing across Ontario and into the bay.

Sediments in James Bay, Canada – October 5th, 2012

Canada – September 30th, 2012

Sediments give the western and southern shores of James Bay, Canada, bright golden, green and brown hues. The sediments on the western side and around Akimiski Island, the largest island in the bay, are lighter and more golden in color. The sediments along the southern shores of the bay, entering through the mouths of the Moose (left) and Harricana (right) Rivers, are significantly darker in color. Also of note in the image are the Belcher Islands, visible in the Hudson Bay in the upper right quadrant. The islands composing the archipelago have unusual, bent, elongated shapes.

Canada – August 10th, 2012

Golden sediments frame the western and southern shores of James Bay, Canada, as well as Akimiski Island, the largest island in the bay with an area of 3,001 km2 (1,159 sq mi). The island is a coastal wetland that includes mudflats, tidal marshes, and tidal mudflats. Freshwater streams that flow into southwestern James Bay carry sediments and abundant nutrients that help to sustain the productive waterfowl habitat around Akimiski Island.
