Recent deposition of 210Pb on the Greenland ice sheet: variations in space and time [PDF]

open access: yes, 1990
Detailed 210Pb profiles were determined for four Chernobyl dated\u27 snowpits sampled during a wide-ranging survey of the Greenland ice sheet during the 1988 season.

Simulating surface height and terminus position for marine outlet glaciers using a level set method with data assimilation [PDF]

open access: yesJournal of Computational Physics, 474:111766, 2023, 2022
We implement a data assimilation framework for integrating ice surface and terminus position observations into a numerical ice-flow model. The model uses the well-known shallow shelf approximation (SSA) coupled to a level set method to capture ice motion and changes in the glacier geometry.

Greenland plateau jets [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2013
The high ice-covered topography of Greenland represents a significant barrier to atmospheric flow and, as a direct and indirect result, it plays a crucial role in the coupled climate system.

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

Continuity of Ice Sheet Mass Loss in Greenland and Antarctica From the GRACE and GRACE Follow‐On Missions

open access: yesGeophysical Research Letters, 2020
We examine data continuity between the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (FO) missions over Greenland and Antarctica using independent data from the mass budget method, which calculates the difference between ice sheet ...

Adding a dynamical cryosphere to iLOVECLIM (version 1.0): coupling with the GRISLI ice-sheet model [PDF]

open access: yesGeoscientific Model Development, 2014
We present a coupling approach to and the first results of the GRISLI ice-sheet model within the iLOVECLIM-coupled climate model. The climate component is a relatively low-resolution earth system model of intermediate complexity, well ...

Dynamic regimes of the Greenland Ice Sheet emerging from interacting melt–elevation and glacial isostatic adjustment feedbacks [PDF]

open access: yesEarth System Dynamics, 2022
The stability of the Greenland Ice Sheet under global warming is governed by a number of dynamic processes and interacting feedback mechanisms in the ice sheet, atmosphere and solid Earth.

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 surface air temperature changes from 1981 to 2019 and implications for ice‐sheet melt and mass‐balance change

open access: yesInternational Journal of Climatology, 2020
We provide an updated analysis of instrumental Greenland monthly temperature data to 2019, focusing mainly on coastal stations but also analysing ice‐sheet records from Swiss Camp and Summit.

Paleo sea-level indicators and proxies from Greenland in the GAPSLIP database and comparison with modelled sea level from the PaleoMIST ice-sheet reconstruction

open access: yesGEUS Bulletin, 2023
One of the most common ways to assess ice-sheet reconstructions of the past is to evaluate how they impact changes in sea level through glacial isostatic adjustment. PaleoMIST 1.0, a preliminary reconstruction of topography and ice sheets during the past
