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

GBaTSv2: a revised synthesis of the likely basal thermal state of the Greenland Ice Sheet [PDF]

open access: yesThe Cryosphere, 2022
The basal thermal state (frozen or thawed) of the Greenland Ice Sheet is under-constrained due to few direct measurements, yet knowledge of this state is becoming increasingly important to interpret modern changes in ice flow. The first synthesis of this

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.

A persistent and dynamic East Greenland Ice Sheet over the past 7.5 million years [PDF]

open access: yes, 2016
Climate models show that ice-sheet melt will dominate sea-level rise over the coming centuries, but our understanding of ice-sheet variations before the last interglacial 125,000 years ago remains fragmentary.

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.

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

The influence of inter-annual temperature variability on the Greenland Ice Sheet volume

open access: yesAnnals of Glaciology, 2023
The Greenland Ice Sheet has become an increasingly larger contributor to sea level rise in the past two decades and is projected to continue to lose mass.

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

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.

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.
