Proglacial Lake Drainage Events Drive Fast Grounding Line Advance in a Warming Climate

Geophysical Research Letters
Proglacial lakes along the retreating margin of the Laurentide ice sheet (LIS) significantly influenced the ice sheet's dynamics. This study investigates the interaction between proglacial lake drainage events and ice sheet evolution during deglaciation.

Global climate evolution during the last deglaciation [PDF]

, 2012
Deciphering the evolution of global climate from the end of the Last Glacial Maximum approximately 19 ka to the early Holocene 11 ka presents an outstanding opportunity for understanding the transient response of Earth’s climate system to external and ...

Late Wisconsinan and Holocene History of the Laurentide Ice Sheet [PDF]

, 1987
Eleven paleogeographic maps and a summary ice retreat map outline the history of advance, retreat, and readvances of the Laurentide Ice Sheet along with associated changes in proglacial drainage and relative sea level oscillations for Late Wisconsinan ...

Landslide Character and Hydrological Thresholds for Slope Failure Initiation on Volcanic Scoria Slopes: Case Study From Mt Hobson/Ōhinerau, Auckland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Rainfall‐induced landslides involving on Auckland Volcanic Field scoria cones are highly unusual, compared with widespread landsliding in the surrounding Auckland clay‐rich residual soils. Indeed, while Auckland can suffer from thousands of rainfall‐induced shallow landslides from severe storms at subdecadal timescales, these are usually limited to ...

The surficial geology record of ice stream catchment dynamics and ice-divide migration in the Quebec-Labrador sector of the Laurentide Ice Sheet

Quaternary Science Advances
The surficial geology of an approximately 30 000 km2 region in northeastern Quebec and western Labrador was mapped to elucidate the glacial dynamics of a region that experienced ice divide migrations and determine the net effect of this evolution on the ...

Calcareous Till Facies North of Lake Superior, Ontario: Implications for Laurentide Ice Streaming [PDF]

, 1988
In the Geraldton and Hemlo areas distantly-derived carbonate tills lie between slightly to non-calcareous tills and can be distinguished by textural, carbonate, and clast compositions. Their occurrence and uniform character over large areas of the Shield

Eccentricity Controls the Magnitude and Periodicity of Pleistocene Glacial Cycles

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract During the Mid‐Pleistocene Transition (∼1,250–750 ka) glacial cycle amplitude and duration increased, from smaller, ∼40 ka‐period middle Pleistocene ice sheets to larger, ∼100 ka‐period late Pleistocene ice sheets. This transition in glacial period and size has been attributed to some combination of long‐term, monotonic, carbon and climate ...

Configuration and Dynamics of the Laurentide Ice Sheet During the Late Wisconsin Maximum [PDF]

, 1982
Prior to 1943 the Laurentide Ice Sheet was considered to have three major domes centered in Keewatin, Labrador, and Patricia (TYRRELL, 1898 a, b; 1913).

Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream Invertebrates

Global Change Biology, Volume 32, Issue 3, March 2026.
Climate change is causing permafrost to thaw, resulting in the formation of large craters in the ground called thaw slumps, which deposit sediments and nutrients into rivers and continually impact stream ecosystems over time. We returned to slump impacted streams 10 years after an initial sample period and found that slumps permanently change streams ...

Glacial and Sea Level History of Lowther and Griffith Islands, Northwest Territories: A Hint of Tectonics [PDF]

, 1993
Lowther and Griffith islands, in the centre of Parry Channel, were overrun by the Laurentide Ice Sheet early in the last glaciation. Northeastward Laurentide ice flow persisted across at least Lowther Island until early Holocene déglaciation.
