Sliding dominates slow-flowing margin regions, Greenland Ice Sheet. [PDF]
Sci Adv, 2019 We measure sliding-dominated plug flow over a hard bed during winter and show that this flow style is typical of margins in Greenland. On the Greenland Ice Sheet (GrIS), ice flow due to deformation and sliding across the bed delivers ice to lower ...

Overshooting the critical threshold for the Greenland ice sheet. [PDF]
Nature, 2023 AbstractMelting of the Greenland ice sheet (GrIS) in response to anthropogenic global warming poses a severe threat in terms of global sea-level rise (SLR)1. Modelling and palaeoclimate evidence suggest that rapidly increasing temperatures in the Arctic can trigger positive feedback mechanisms for the GrIS, leading to self-sustained melting2–4, and the

Clouds enhance Greenland ice sheet meltwater runoff
Nature Communications, 2016 Clouds play a pivotal role in the energy and mass balance of the Greenland ice sheet, thereby affecting its contribution to global sea-level rise. Here, using a combination of observations and model simulations, the authors show that clouds enhance ...

Ice algal bloom development on the surface of the Greenland Ice Sheet [PDF]
FEMS Microbiology Ecology, 2018 It is fundamental to understand the development of Zygnematophycean (Streptophyte) micro‐algal blooms within Greenland Ice Sheet (GrIS) supraglacial environments, given their potential to significantly impact both physical (melt) and chemical (carbon and

Drill-site selection for cosmogenic-nuclide exposure dating of the bed of the Greenland Ice Sheet [PDF]
The Cryosphere, 2022 Direct observations of the size of the Greenland Ice Sheet during Quaternary interglaciations are sparse yet valuable for testing numerical models of ice-sheet history and sea level contribution. Recent measurements of cosmogenic nuclides in bedrock from

The undiscovered biosynthetic potential of the Greenland Ice Sheet microbiome. [PDF]
Front Microbiol, 2023 The Greenland Ice Sheet is a biome primarily driven by microbial activity. Despite the harsh conditions, such as cold temperatures, low nutrient levels, high UV radiation in summer, and long dark winters, various niches can be found on the ice sheet that can support organisms capable of withstanding these challenges.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Greenland ice sheet climate disequilibrium and committed sea-level rise
Nature Climate Change, 2022 Ice loss from the Greenland ice sheet is one of the largest sources of contemporary sea-level rise (SLR). While process-based models place timescales on Greenland’s deglaciation, their confidence is obscured by model shortcomings including imprecise ...

ICE FLOW VELOCITY MAPPING IN GREENLAND USING HISTORICAL IMAGES FROM 1960s TO 1980s: SCHEME DESIGN [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Ice flow velocity over long time series in Greenland plays a vital role in estimating and predicting the mass balance of the Greenland Ice Sheet and its contribution to global sea level rise.

Hydrology and the future of the Greenland Ice Sheet. [PDF]
Nat Commun, 2018 Detection, attribution and projection of mass loss from the Greenland Ice Sheet has been a central focus of the glaciological community, with surface meltwater thought to play a key role in feedbacks that could accelerate sea-level rise. While the prospect of runaway sliding has faded, much remains uncertain when it comes to the role of surface runoff ...
