Lake Winnipeg and Nelson River in Manitoba, Canada

Canada – May 20th, 2013

Ice covers the northern part of Lake Winnipeg, in Manitoba, Canada, visible at the center of the bottom edge of this image. The shores of the Hudson Bay are also lined with ice (upper right quadrant), and sediments can be seen spilling from the Nelson River into the bay.

Climate change has the potential to affect the ecology and biology of Lake Winnipeg. Climate-forcing scenarios predict increases in mid-summer temperatures through the 21st century, with even greater increases in mid-winter temperatures, extending the open water season.

Climate Change and Ice-covered Lake Winnipeg, Canada – May 6th, 2013

Canada – May 6th, 2013

Lake Winnipeg is the largest aquatic life support system in Manitoba, covering some 24,500 sq km. It sustains a complex food web and the largest commercial fishery west of the Laurentian Great Lakes.

Like many natural systems, the lake is shaped by environmental forces and disturbed by human activities. Weather, climate, and geology regulate the growth and reproduction of its plants and animals.

But excess nutrients from urbanization, agriculture and economic development in the Lake Winnipeg watershed are impairing its water quality and, in spite of its size, Lake Winnipeg is susceptible to the impacts of climate change (click here for more information).

Smoke South of Lakes Winnipeg and Winnipegosis, Canada

Canada – August 30th, 2012

A wispy swath of smoke blows diagonally across this image, south of Lake Winnipeg (upper right) and Lake Winnipegosis (upper left), in Manitoba, Canada. The smoke likely originates from fires in the western USA. Both lakes show considerable amounts of sediments and perhaps algal growth, although those in the latter are considerably lighter and brighter green than those in the former.

Fires by Lake Winnipeg and Saskatchewan-Manitoba Border, Canada

Canada – July 13th, 2012

Multiple plumes of smoke from fires in Canada near the Saskatchewan-Manitoba border can be seen blowing towards the southeast. A veil of smoke also sweeps in an arched shape across the upper half of the image, while Lake Winnipeg and other nearby bodies of water are also covered in a smoky haze in the lower right quadrant.

Smoke Blowing Over Lakes Winnipeg and Winnipegosis, Canada

Canada - May 14th, 2012

Smoke blows across the Canadian provinces of Saskatchewan (left) and Manitoba (right), but does not reach southward over the border with the United States (lower half of image, smoke-free). The veil of smoke is denser over Saskatchewan, yet manages to hinder the viewing of Lake Winnipeg (right) and Lake Winnipegosis (left, slightly lighter in color than the former, due to sediments), in Manitoba.
