Ice flow dynamics of the northwestern Laurentide Ice Sheet during the last deglaciation [PDF]
The CryosphereReconstructions of palaeo-ice-stream activity provide insight into the processes governing ice stream evolution over millennial timescales. The northwestern sector of the Laurentide Ice Sheet experienced a period of rapid retreat driven by warming during

Atmospheric River Contributions to Ice Sheet Hydroclimate at the Last Glacial Maximum
Geophysical Research Letters, 2023 Atmospheric rivers (ARs) are an important driver of surface mass balance over today's Greenland and Antarctic ice sheets. Using paleoclimate simulations with the Community Earth System Model, we find ARs also had a key influence on the extensive ice ...

Cosmogenic ages indicate no MIS 2 refugia in the Alexander Archipelago, Alaska [PDF]
Geochronology, 2022 The late-Pleistocene history of the coastal Cordilleran Ice Sheet remains relatively unstudied compared to chronologies of the Laurentide Ice Sheet. Yet accurate reconstructions of Cordilleran Ice Sheet extent and the timing of ice retreat along the ...

Eastern Beringia and beyond: Late Wisconsinan and Holocene landscape dynamics along the Yukon Coastal Plain, Canada [PDF]
, 2012 Terrestrial permafrost archives along the Yukon Coastal Plain (northwest Canada) have recorded landscape development and environmental change since the Late Wisconsinan at the interface of unglaciated Beringia (i.e.

Ice streams in the Laurentide Ice Sheet: a new mapping inventory [PDF]
Journal of Maps, 2014 Rapidly flowing ice streams dominate the drainage of continental ice sheets and are a key component of their mass balance. Due to their potential impact on sea level, their activity in the Antarctic and Greenland Ice Sheets has undergone detailed scrutiny in recent decades.

Arctic ice export events and their potential impact on global climate during the late Pleistocene [PDF]
, 2002 Ice sheets in the North American Arctic and, to a lesser extent, those in northern Eurasia calved large quantities of icebergs that drifted through Fram Strait into the Greenland Sea several times during the late Pleistocene.

Fossil Java Sea corals record Laurentide ice sheet disappearance [PDF]
Geology, 2023 Abstract The Laurentide ice sheet was the largest late Pleistocene ice mass and the largest contributor to Holocene pre-industrial sea-level rise. While glaciological dates suggest final ice sheet melting between 8 and 6 ka, inversion of sea-level data indicates deglaciation at ca. 7 ka.

Evolution of the large-scale atmospheric circulation in response to changing ice sheets over the last glacial cycle [PDF]
Climate of the Past, 2014 We present modelling results of the atmospheric circulation at the cold periods of marine isotope stage 5b (MIS 5b), MIS 4 and the Last Glacial Maximum (LGM), as well as the interglacial.

Northern Hemisphere ice sheet and ocean interactions during the last glacial period in a coupled ice sheet–climate model [PDF]
Climate of the PastThis study examines the interactions between the Northern Hemisphere ice sheets and the ocean during the last glacial period. Using the iLOVECLIM climate model of intermediate complexity and the GRISLI ice sheet model, we explore the consequences of an ...
