Drill-site selection for cosmogenic-nuclide exposure dating of the bed of the Greenland Ice Sheet [PDF]

open access: yesThe 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]

open access: yesFront 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.

Greenland ice sheet climate disequilibrium and committed sea-level rise

open access: yesNature 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]

open access: yesThe 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.

Programme for Monitoring of the Greenland Ice Sheet (PROMICE) automatic weather station data

open access: yesEarth System Science Data, 2021
. The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) has been measuring climate and ice sheet properties since 2007. Currently, the PROMICE automatic weather station network includes 25 instrumented sites in Greenland.

Investigating the local-scale influence of sea ice on Greenland surface melt [PDF]

open access: yesThe Cryosphere, 2017
Rapid decline in Arctic sea ice cover in the 21st century may have wide-reaching effects on the Arctic climate system, including the Greenland ice sheet mass balance. Here, we investigate whether local changes in sea ice around the Greenland ice sheet

Hydrology and the future of the Greenland Ice Sheet. [PDF]

open access: yesNat 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 ...

Greenland Ice Sheet Ice Slab Expansion and Thickening

open access: yesGeophysical Research Letters, 2022
We use airborne accumulation radar data acquired over the Greenland Ice Sheet between 2002 and 2018 to identify changes in ice slab extent and thickness. We show that ice slabs several metres thick were already present at least as early as 2002. Between 2012 and 2018, they expanded 13,400-17,600  inland, or by 37-44%.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical 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.

Ice dynamics will remain a primary driver of Greenland ice sheet mass loss over the next century

open access: yesCommunications Earth & Environment, 2021
The mass loss of the Greenland Ice Sheet is nearly equally partitioned between a decrease in surface mass balance from enhanced surface melt and an increase in ice dynamics from the acceleration and retreat of its marine-terminating glaciers.
