Mackenzie River Spilling Sediments into the Arctic Ocean off Canadian Coast
Despite some cloud cover, the Mackenzie River can be see flowing north across Canada into the Arctic Ocean. The river, which originates in Great Slave Lake, in the Northwest Territories, is the longest river in Canada at 1,738 kilometres (1,080 mi).
Together with its headstreams the Peace and the Finlay, it is the second longest river in North America at 4,241 kilometres (2,635 mi) in length.
The Mackenzie and its tributaries drain 1,805,200 square kilometers. Its mean discharge is 10,700 cubic metres per second. Here, it can be seen spilling brown sediments into the Arctic Ocean.
The large marshy delta of the Mackenzie River (see close-up) provides habitat for migrating snow geese, tundra swans and brant, as well as a breeding habitat for other waterfowl. The estuary is also a calving area for Beluga whales.
