Canada - May 1st, 2011

The Saint Lawrence River can be seen here, traversing the Canadian province of Quebec. Sediments drain from the river into the Gulf of Saint Lawrence, one of the largest estuaries in the world.

Another river, the Saguenay River, can be seen draining into the estuary from Saint-Jean Lake, a large, relatively shallow lake in the Laurentian Highlands of south-central Quebec. The lake, which is frozen in this image, covers an area of 1003 km² (387 sq. mi.), and is 63 metres (207 ft) at its deepest point.

Another frozen lake, the ring-shaped Manicouagan Reservoir, can also be observed near the top edge, covering an area of 1,942 km². The lake’s distinct annular shape is because it lies within the remnant of an ancient eroded impact crate.

Canada - April 15th, 2011

Snow dusts the Canadian landscape around the Gulf of Saint Lawrence. The lower reaches of the gulf appear brownish in color due to the influx of sediments from the Saint Lawrence River.

Sediments can also be observed in the Bay of Fundy (lower right quadrant), although the shores around it are mostly snow free.

A third notable body of water, the frozen, ring-shaped Manicouagan Reservoir, can be observed at the top center, north of the Gulf of Saint Lawrence.

The Saint Lawrence River flows diagonally across this image to the Gulf of Saint Lawrence (right), in Canada. Another visible body of water is the frozen, ring-shaped Manicouagan Reservoir (top right).

The Gulf of Saint Lawrence is the world’s largest estuary and the outlet of North America’s Great Lakes via the Saint Lawrence River into the Atlantic Ocean.

It is a semi–enclosed sea, covering an area of about 236,000 km2 (91,000 sq mi) and containing 35,000 km3 (7.7×1015 imp gal) of water.

Snow dusts the landscape of southeastern Quebec, Canada, both north and south of the Saint Lawrence River (left edge) and Gulf of Saint Lawrence (top center, right). In the full image, part of the northeastern United States is visible as well. States such as Massachusetts and Rhode Island are snow-free.

The white circle in the upper left corner is the frozen Manicouagan Reservoir, sometimes called “The Eye of Quebec” due to its ring shape. It has this unusual shape because the lake lies in the remnants of an ancient, eroded impact crater from an asteroid.

Canada and USA - August 29th, 2010

The medium blue body of water on the left side of this image is Lake Ontario, on the border of the USA and Canada. The northeastern tip of Lake Huron can also be seen just below, along the left edge. South of Lake Ontario are several long, thin, parallel lakes known as the Finger Lakes (best observed in the full image) in New York State, USA.

The Saint Lawrence River runs out of the eastern end of Lake Ontario and passes the cities of Montreal and Quebec City on its way to the Gulf of Saint Lawrence (upper right quadrant). There, it can be seen releasing tan sediments into the gulf.

The city of Ottawa can also be observed west of Montreal, on the Ottawa River, one of the Saint Lawrence’s tributaries. The two rivers converge by Montreal.
