Canada's lakes and rivers account for approximately 20% of the world's freshwater resources, with much of this water held in large northern lakes and their expansive watersheds. These lakes have been the focus of curiosity, beginning with early exploratory expeditions of pre-confederation Canada ...
The Great Lakes helped make the U.S. an economic powerhouse. Now climate change, pollution, and invasive species threaten their complex ecosystems.
Regional water balance trends and evaporation-transpiration partitioning from a stable isotope survey of lakes in northern Canada: Regional water balance using stable isotopes Global Biogeochem. Cycles, 16 (2) (2002), pp. 10-1-10-14, 10.1029/2001GB001839 Google Scholar Gibson and Reid, 2010 J...
Sediment cores collected from several lakes in northern Canada have been analyzed for mercury and several other chemical contaminants. Sites ranged from the Experimental Lakes Area of northwestern Ontario, north to Comwallis Island, and west to the southern Yukon. Cores were sliced at sites of colle...
Great Lakes- a group of five large, interconnected lakes in central North America Canada- a nation in northern North America; the French were the first Europeans to settle in mainland Canada; "the border between the United States and Canada is the longest unguarded border in the world" ...
In the 16 years of data, Great Bear and Great Slave lakes in northern Canada saw the greatest increases in productivity, while Lake Tanganyika in southeastern Africa has seen decreases. The trends are linked to increases in water temperatures, as well as solar radiation and a reduction in wind...
Koocanusa, is formed by the Libby dam. It has a capacity of 5,809,000 acre-feet and the eighth largest man-made lake in the US. The reservoir provides water supply, hydroelectric power, wildlife habitat and flood protection. The water supply is for the United States as well as Canada. ...
Michigan is high in the northern latitudes, and about four months of the year it binds water ice. 4. Lake Huron via Lake Huron, on the US border and Canada, an area of 59.600 km2, has a depth of 229 meters and a height of 176 meters above sea level. Most interesting is that Lake...
Lake Pend Oreille in northern Idaho. Shaped a bit like a human ear—its name roughly means “ear pendant” in French— Lake Pend Oreille lies in the Idaho panhandle. Carved out by glaciers during the lastice age, it may have been partially filled by aseries of mega floodsthat tore across...
CANADATHE discovery of density stratification in Lake Tuborg, northern Ellesmere Island (lat. 80° 50′ N, long. 79° W) 1 , alerted us to the possibility that other lakes in the area might show the same phenomenon, provided they were near enough to sea level to allow the trapping of ...
