Akimiski Island in Icy James Bay, Canada

Canada - April 15th, 2011

Ice covers most of James Bay, the southern extension of the Hudson Bay along the shores of the provinces of Ontario (left) and Quebec (right), Canada.

The ice appears thickest along the shoreline and framing the northern half of Akimiski Island (near the left shores of the bay). In the full image, many cracks can be seen in the ice in the rest of the bay. The only large ice-free area is south of Akimiski Island.

Several rivers appear as white lines across the snow-dusted landscape of the mainland. Three of the main rivers observable here (from northwest to southeast) are the Albany River, the Attawapiskat River and the Moose River.


Frozen James Bay and Icy Akimiski Island, Canada

Canada - March 30th, 2011

James Bay, the southern extension of the Hudson Bay, is still mostly covered in ice in this early spring image of Canada. The land west of the bay is part of the province of Ontario, while that to the east belongs to Quebec.

While an apparently thick sheet of ice surrounds Akimiski Island and lines the shores of the bay, the ice is the upper part of the image is cracking (see full image).

The snow dusting the shoreline highlights several frozen rivers, including (from northwest to southeast) the Albany River, the Attawapiskat River and the Moose River.

Three Rivers Empyting Dark Brown Sediments into James Bay, Canada

Canada - October 12th, 2010

Thick brown sediments pour out of rivers along the southeastern coast of James Bay, part of Hudson Bay, near Akimiski Island, in Canada. The sediments are densest and darkest brown by the rivermouths, becoming golden tan and then green in color as the bay’s waters dilute them.

From northwest to southeast, these rivers are: the Albany River, the Attawapiskat River and the Moose River. In the full image, they all appear as navy blue lines surrounded by braided green channels.

The Albany River is 982 kilometres (610 mi) long; at the end of its course it empties into the Akimiski Strait on James Bay via a series of channels. The river is navigable for the first 400 kilometres (249 mi).

The Attawapiskat River travels a distance of 748 kilometres (465 mi), and has a drainage area of 50,500 square kilometres (19,498 sq mi). The Moose River’s full length is 547 kilometers (340 mi), its drainage basin is 108,500 km² and it has a mean discharge rate of 1370 m³/s.

James Bay, Canada - October 6th, 2008

James Bay is a southeastern extension of the Hudson Bay, bordered by the Canadian province of Quebec to the East, and the province of Ontario to the West. It is also the southernmost area of the Arctic Archipelago Marine ecozone, and its eastern shores make the western edge of the Canadian Shield (a large, geological shield covered by a blanket of soil extending over half of Canada) in Quebec.

The landscape near the eastern shores is characterized by rocky, hilly terrain with boreal forest. On the other hand, the terrain around the western shore consists of tundra lowlands. Much of this region is part of the Polar Bear Provincial Park.

James Bay is fed by hundreds of rivers, which all tend to be wide and shallow in the area close to the bay known as the James Bay Lowlands, and steeper and narrower upstream as they come off the Canadian Shield. In the main image, we can see the colorful mixture of the sediments flowing into the bay from the many rivers and the green algal bloom along the shoreline.

In our first close-up we can clearly see the sediments and algal bloom around Akimiski Island, the largest island in James Bay and a coastal wetland with mudflats, tidal marshes and tidal mudflats. Although it is currently uninhabited, the island has a Migratory Bird Sanctuary. The sediments and nutrients flowing into James Bay from freshwater streams and rivers sustain the wetlands of the island, making it a rich habitat and an important feeding ground for many species of migratory birds.

In the second image detail, we can see the sediments flowing out from the mouths of the Albany River (upper left) and the Moose River (lower right). The Albany River is the longest river in Ontario: 980 kilometres (609 mi) long and navigable for 400 kilometres (249 mi). It has a drainage basin of 135,200 square kilometres (52,201 sq mi). The Moose River, on the other hand, has a drainage basin of 108,500 km² and a mean discharge rate of 1370 m³/s. The area around its mouth is home to another important Migratory Bird Sanctuary.

In the final image detail, we can observe a cluster of islands that form the Belcher Islands archipelago. The archipelago is actually comprised of 1500 small islands.
