Freshwater Forcing of Abrupt Climate Change During the Last Glaciation
Large millennial-scale fluctuations of the southern margin of the North American Laurentide Ice Sheet occurred during the last deglaciation, when the margin was located between about 43° and 49°N.Expand

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

Contribution of Alaskan glaciers to sea-level rise derived from satellite imagery
Over the last 50 years, retreating glaciers and ice caps (GIC) contributed 0.5 mm/yr to sea level rises (SLR), and one third is believed to originate from ice masses bordering the Gulf of Alaska.Expand

Hydraulics of subglacial outburst floods: new insights from the Spring-Hutter formulation
Using a slightly modified form of the Spring-Hutter equations, glacial outburst floods are simulated from three classic sites, Hazard Lake, Yukon, Canada, Summit Lake, British Columbia, Canada, andExpand

Ice-dammed lakes and rerouting of the drainage of northern Eurasia during the Last Glaciation.
During the Quaternary period, ice sheets centred over the Barents and Kara seas expanded several times onto mainland Russia and blocked northflowing rivers, such as the Yenissei, Ob, Pechora andExpand

SUBGLACIAL PROCESSES
■ Abstract Processes operating beneath glaciers can have a greater influence on flow dynamics than those operating within them. The variety and complexity of these processes, which involveExpand

Subglacial till: A physical framework for its properties and processes
The continuum theory of mixtures provides a framework around which present knowledge of subglacial till can be organized. The proposed framework is provisional in two senses: the constitutiveExpand

Flow, thermal structure, and subglacial conditions of a surge-type glacier
Temperature measurements in a subpolar surge-type glacier reveal a distinctive thermal structure associated with the boundary between the ice reservoir and receiving areas. In the receiving area theExpand

History of the Greenland Ice Sheet: paleoclimatic insights
Abstract Paleoclimatic records show that the Greenland Ice Sheet consistently has lost mass in response to warming, and grown in response to cooling. Such changes have occurred even at times of slowExpand
