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

Geoscientific 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 ...

A temperate former West Antarctic ice sheet suggested by an extensive zone of bed channels [PDF]

, 2014
Several recent studies predict that the West Antarctic Ice Sheet will become increasingly unstable under warmer conditions. Insights on such change can be assisted through investigations of the subglacial landscape, which contains imprints of former ice ...

Ice sheets as a significant source of highly reactive nanoparticulate iron to the oceans [PDF]

, 2014
The Greenland and Antarctic Ice Sheets cover ~\n10% of global land surface, but are rarely considered as active components of the global iron cycle. The ocean waters around both ice sheets harbour highly productive coastal ecosystems, many of which are ...

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

, 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 ...

What Darkens the Greenland Ice Sheet?

Eos, 2015
Limited observational data sets and incomplete surface energy balance models constrain understanding of the driving processes for Greenland's ice sheet.

Evidence of local and regional freshening of Northeast Greenland coastal waters [PDF]

, 2017
The supply of freshwater to fjord systems in Greenland is increasing as a result of climate change-induced acceleration in ice sheet melt. However, insight into the marine implications of the melt water is impaired by lack of observations demonstrating ...

The effect of a Holocene climatic optimum on the evolution of the Greenland ice sheet during the last 10 kyr

Journal of Glaciology, 2018
The Holocene climatic optimum was a period 8–5 kyr ago when annual mean surface temperatures in Greenland were 2–3°C warmer than present-day values. However, this warming left little imprint on commonly used temperature proxies often used to derive the ...

Greenland Ice Sheet - Higher non-linearity of ice flow significantly reduces estimated basal motion [PDF]

, 2018
In times of warming in polar regions, the prediction of ice sheet discharge is of utmost importance to society, because of its impact on sea level rise. In simulations the flow rate of ice is usually implemented as proportional to the differential stress

Greenland ice sheet mass balance assessed by PROMICE (1995–2015)

Geological Survey of Denmark and Greenland Bulletin, 2019
The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) has measured ice-sheet elevation and thickness via repeat airborne surveys circumscribing the ice sheet at an average elevation of 1708 ± 5 m (Sørensen et al. 2018).

Using results from the PlioMIP ensemble to investigate the Greenland Ice Sheet during the mid-Pliocene Warm Period [PDF]

Climate of the Past, 2015
During an interval of the Late Pliocene, referred to here as the mid-Pliocene Warm Period (mPWP; 3.264 to 3.025 million years ago), global mean temperature was similar to that predicted for the end of this century, and atmospheric carbon dioxide ...
