Canada - October 14th, 2010

Golden tan sediments surround Akimiski Island, the largest island in James Bay (a southeasterly extension of Hudson Bay). The island is part of the Candian territory of Nunavut, although the mainland visible to the west and south belongs to the province of Ontario.

In the full image, part of the James Bay coastline by the border between Ontario and Quebec can also be seen, to the right, beyond the clouds. Two bays are visible in this border area, both of which are various shades of brown from sediments.

To the right, within Quebecois territory, is Rupert Bay. Sediments pour into the bay from the Rupert River, one of the largest rivers in Quebec. It drains an area of 43,400 square kilometres (16,757 sq mi). In this image, the lower portions of the bay near the rivermouth, are dark brown, becoming lighter as one moves into the main body of James Bay.

Just west of Rupert Bay is an indentation known as Southern James Bay. It is a Canadian coastal wetland complex in northeastern Ontario bordering James Bay and Quebec. Southern James Bay lies within the flat sedimentary basin of the Hudson Bay lowland in the Hudson Plains ecozone, and its coast is characterised by a sequence of mudflats, intertidal marshes and supertidal meadow-marshes, which grade through a willow-alder shrub area into a drier forest interspersed with fens and bogs.
