Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]

open access: yesThe Cryosphere, 2013
We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability

An ice sheet model validation framework for the Greenland ice sheet [PDF]

open access: yesGeoscientific Model Development, 2016
Abstract. We propose a new ice sheet model validation framework – the Cryospheric Model Comparison Tool (CmCt) – that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the Greenland ice sheet.

Variations of Mass Balance of the Greenland Ice Sheet from 2002 to 2019

open access: yesRemote Sensing, 2020
The melting of the polar ice caps is considered to be an essential factor for global sea-level rise and has received significant attention. Quantitative research on ice cap mass changes is critical in global climate change.

Evidence of meltwater retention within the Greenland ice sheet [PDF]

open access: yesThe Cryosphere, 2013
Greenland ice sheet mass losses have increased in recent decades with more than half of these attributed to surface meltwater runoff. However, the magnitudes of englacial storage, firn retention, internal refreezing and other hydrologic processes that ...

Greenland bare-ice albedo from PROMICE automatic weather station measurements and Sentinel-3 satellite observations

open access: yesGEUS Bulletin, 2021
The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) provides surface meteorological and glaciological measurements from widespread on-ice automatic weather stations since mid-2007.

The Chernobyl Reference Horizon (?) in the Greenland Ice Sheet [PDF]

open access: yes, 1989
Published reports of the presence of radioactive debris from the Chernobyl reactor accident in snow on the Greenland ice sheet raised the strong prospect that such debris might constitute a valuable time stratigraphic marker all over the ice sheet. Large

Response of a marine-terminating Greenland outlet glacier to abrupt cooling 8200 and 9300 years ago [PDF]

open access: yes, 2011
Long-term records of Greenland outlet-glacier change extending beyond the satellite era can inform future predictions of Greenland Ice Sheet behavior. Of particular relevance is elucidating the Greenland Ice Sheet's response to decadal- and centennial ...

Twenty-first century ocean forcing of the Greenland ice sheet for modelling of sea level contribution [PDF]

open access: yesThe Cryosphere, 2020
Changes in ocean temperature and salinity are expected to be an important determinant of the Greenland ice sheet's future sea level contribution. Yet, simulating the impact of these changes in continental-scale ice sheet models remains challenging due to

The GRISLI-LSCE contribution to the Ice Sheet Model Intercomparison Project for phase 6 of the Coupled Model Intercomparison Project (ISMIP6) – Part 1: Projections of the Greenland ice sheet evolution by the end of the 21st century [PDF]

open access: yesThe Cryosphere, 2021
Polar amplification will result in amplified temperature changes in the Arctic with respect to the rest of the globe, making the Greenland ice sheet particularly vulnerable to global warming. While the ice sheet has been showing an increased mass loss in

Circum-Greenland, ice-thickness measurements collected during PROMICE airborne surveys in 2007, 2011 and 2015 [PDF]

open access: yes, 2018
The Greenland ice sheet has experienced an average mass loss of 142 ± 49 Gt/yr from 1992 to 2011 (Shepherd et al. 2012), making it a significant contributor to sea-level rise.
