    QUATERNARY RESEARCH 1, () Retreat of the Laurentide Ice Sheet F to Years Ago H. E. WRIGHT, JR.' The intricate pattern of moraines of the Laurentide ice sheet in the Great Lakes region reflects the marked lobation of the ice margin in late Wisconsin time, and this in turn reflects the distribution of steam-cut lowlands etched in preglacial times in the weak-rock belts Cited by: A. the region where a body of water empties into an ocean or lake. B. a known source of pollution. C. all of the land area that drains into a body of water. D. the immediate shoreline area that surrounds a lake.

      Piston cores from deep-water bottom deposits in Lake Ontario contain shallow-water sediments such as, shell-rich sand and silt, marl, gyttja, and formerly exposed shore deposits including woody detritus, peat, sand and gravel, that are indicative of past periods of significantly lower water levels. These and other water-level indicators such as changes in rates of sedimentation, mollusc Cited by:   The climate of the last deglaciation is marked by a series of abrupt changes in temperature. Of particular note is the Younger Dryas (YD) episode at ca. ka that is often described as a millennial-length rapid return to glacial-like conditions over much of the North Atlantic region (Alley, ).While a variety of mechanisms have been proposed to explain this cooling, including a volcanic.

The evolution of Lakes Barlow and Ojibway, two large ice-contact glacial lakes that covered parts of northern Ontario and western Québec from about – ka BP, during the retreat of the Laurentide Ice Sheet, was reconstructed using deglaciation landforms, ice-flow indicators inscribed on bedrock, 14 C dates of early postglacial vegetation accumulated in lake basins, the distribution of Cited by: Bering Glacier is the foremost glacier of this system, with one of the largest proglacial lake-river systems in the world, Vitus Lake, which is linked to the Gulf of Alaska by the Seal River.

Vitus Lake, at sea level and > m deep in some locations, receives all of the runoff, rainfall, and glacial melt from the Bering Lobe, which then flows. At that time, an ice-dammed lake reached its maximum water level, which was around m above present sea level.

Drainage of the lake started shortly after 15 ka ago, and the lake was emptied. Supplement to the research article in Sedimentology titled "Turbidite stratigraphy in proglacial lakes – deciphering trigger mechanisms using a statistical approach" by Praet et al.

MEASUREMENT, CORRELATION, AND MAPPING OF GLACIAL LAKE ALGONQUIN SHORELINES IN NORTHERN MICHIGANAuthor: et al Schaetzl, Randall J. The sediments of Lake Superior include a sequence of rhythmites that should provide an annual stratigraphic record of eastern Lake Agassiz discharge and regional deglaciation (Fig.

Low oxygen levels may restrict where fish can go within a lake and limit the types and numbers of fish in the lake's bottom waters.

Partial harvesting has been proposed as a key aspect to implementing ecosystem management in the Canadian boreal forest.
