Freshwater outbursts to the oceans from glacial Lake Agassiz and their role in climate change during the last deglaciation
Abstract Lake Agassiz was the largest lake in North America during the last deglaciation. As the Laurentide Ice Sheet (LIS) retreated, large volumes of water stored in this proglacial lake wereExpand

Paleohydraulics of the Last Outburst Flood from Glacial Lake Agassiz and the 8200 BP Cold Event
Abstract During the last deglaciation of North America, huge proglacial lakes formed along the southern margin of the Laurentide Ice Sheet. The largest of these was glacial Lake Agassiz, which formedExpand

Glacial Lake Agassiz: A 5000 yr history of change and its relationship to the δ18O record of Greenland
Lake Agassiz was the largest lake in North America during the last period of deglaciation; the lake extended over a total of 1.5 × 10 6 km 2 before it drained at ca. 7.7 14 C ka (8.4 cal. [calendar]Expand

Changes in the bathymetry and volume of glacial Lake Agassiz
Computer reconstructions of the bathymetry of the lake were used to quantify variations in the size and form of Lake Agassiz during its final two phases (the Nipigon and Ojibway phases), betweenExpand

Superlakes, Megafloods, and Abrupt Climate Change
About 8200 years ago, the climate of much of the Northern Hemisphere cooled abruptly for a period of about 200 years. In their Perspective, Clarke et al . examine the most likely culprit for thisExpand

Changes in the Bathymetry and Volume of Glacial Lake Agassiz Between 11,000 and 9300 14C yr B.P.
The volume and surface area of glacial Lake Agassiz varied considerably during its 4000-year history. Computer models for seven stages of Lake Agassiz were used to quantify these variations over theExpand

A Large Paleolake Basin at the Head of Ma'adim Vallis, Mars
At 8 to 15 kilometers wide, Ma'adim Vallis is one of the largest valleys in the martian highlands. Although a groundwater source was previously suggested, the channel originates at a spillway in theExpand

Volcanic rilles, streamlined islands, and the origin of outflow channels on Mars
[1] The widely accepted view that catastrophic flow of liquid water was the dominant process involved in formation of outflow channels on Mars has as part of its foundation the assumption that theExpand
