Simulating the Early Holocene demise of the Laurentide Ice Sheet with BISICLES (public trunk revision 3298) [PDF]
Geoscientific Model Development, 2020 Simulating the demise of the Laurentide Ice Sheet covering Hudson Bay in the Early Holocene (10–7 ka) is important for understanding the role of accelerated changes in ice sheet topography and melt in the 8.2 ka event, a century long ...

How might the North American ice sheet influence the northwestern Eurasian climate? [PDF]
Climate of the Past, 2015 It is now widely acknowledged that past Northern Hemisphere ice sheets covering Canada and northern Europe at the Last Glacial Maximum (LGM) exerted a strong influence on climate by causing changes in atmospheric and oceanic circulations.

Sensitivity of Heinrich-type ice-sheet surge characteristics to boundary forcing perturbations [PDF]
Climate of the Past, 2023 Heinrich-type ice-sheet surges are one of the prominent signals of glacial climate variability. They are characterised as abrupt, quasi-periodic episodes of ice-sheet instabilities during which large numbers of icebergs are released from the Laurentide ...

The evolution of the Patagonian Ice Sheet from 35 ka to the present day (PATICE)
Earth-Science Reviews, 2020 We present PATICE, a GIS database of Patagonian glacial geomorphology and recalibrated chronostratigraphic data. PATICE includes 58,823 landforms and 1,669 ages, and extends from 38°S to 55°S in southern South America.

Antarctic Ice Sheet paleo-constraint database [PDF]
Earth System Science Data, 2023 We present a database of observational constraints on past Antarctic Ice Sheet changes during the last glacial cycle intended to consolidate the observations that represent our understanding of past Antarctic changes and for state-space estimation and ...

The microbiome of glaciers and ice sheets [PDF]
npj Biofilms and Microbiomes, 2017 AbstractGlaciers and ice sheets, like other biomes, occupy a significant area of the planet and harbour biological communities with distinct interactions and feedbacks with their physical and chemical environment. In the case of the glacial biome, the biological processes are dominated almost exclusively by microbial communities.

Mineral phosphorus drives glacier algal blooms on the Greenland Ice Sheet
Nature Communications, 2021 Melting of the Greenland Ice Sheet is a leading cause of land-ice mass loss and cryosphere-attributed sea level rise. Blooms of pigmented glacier ice algae lower ice albedo and accelerate surface melting in the ice sheet’s southwest sector.

The future sea-level contribution of the Greenland ice sheet: a multi-model ensemble study of ISMIP6
The Cryosphere, 2020 . The Greenland ice sheet is one of the largest contributors to global mean sea-level rise today and is expected to continue to lose mass as the Arctic continues to warm.

Dynamic ice loss from the Greenland Ice Sheet driven by sustained glacier retreat
Communications Earth & Environment, 2020 The Greenland Ice Sheet is losing mass at accelerated rates in the 21st century, making it the largest single contributor to rising sea levels. Faster flow of outlet glaciers has substantially contributed to this loss, with the cause of speedup, and ...

Emergence of the Shackleton Range from beneath the Antarctic Ice Sheet due to glacial erosion [PDF]
, 2014 This paper explores the long-term evolution of a subglacial fjord landscape in the Shackleton Range, Antarctica. We propose that prolonged ice-sheet erosion across a passive continental margin caused troughs to deepen and lower the surrounding ice-sheet ...
