Sediments around Akimiski Island, Canada – July 11th, 200952.9N 81.3W
Dark and light brown sediments line the coast of James Bay (a southeasterly extension of Hudson Bay), Canada, and Akimiski Island, the bay’s largest island.
The island has an area of 3 001 km² (1,159 square miles), making it Canada’s 29th largest island.
Although it is part of the territory of Nunavut, Akimiski Island is only 19 km from the province of Ontario. Standing on the western side of the island, one can see the Ontario coastline.
The island is a coastal wetland that includes mudflats, tidal marshes, and tidal mudflats. Freshwater streams that flow into southwestern James Bay carry sediments, visible here, and abundant nutrients that help to sustain the productive waterfowl habitat around Akimiski Island.
The surface of Akimiski is flat and slopes gradually to the north. Most of the vegetation that covers the island consists of lichen, moss, sedges, and dwarf Black Spruce.
Lake Nipigon can also be seen here, in the lower left corner. It is the largest lake entirely within the boundaries of the Canadian province of Ontario. It is noted for its towering cliffs and unusual green-black sand beaches composed of the fine particles of a dark green mineral known as pyroxene.
