An ice sheet model validation framework for the Greenland ice sheet [PDF]
Geoscientific Model Development, 2017 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 ...

Hysteresis of the Antarctic Ice Sheet With a Coupled Climate‐Ice‐Sheet Model
Geophysical Research LettersThe stability of the Antarctic ice sheet under different fixed CO2 levels and orbital configurations is explored using a coupled climate‐ice sheet model, starting from either a pre‐industrial ice sheet or an ice‐free, isostatically rebounded geometry ...

The microbiome of glaciers and ice sheets [PDF]
npj Biofilms and Microbiomes, 2017 AbstractGlaciers and ice sheets, like other biomes, occupy a significant area of the planet and harbour biological communities with distinct interactions and feedbacks with their physical and chemical environment. In the case of the glacial biome, the biological processes are dominated almost exclusively by microbial communities.

Philosophical Transactions of the Royal Society B: Biological Sciences, 2013 Snow and ice play their most important role in the nitrogen cycle as a barrier to land–atmosphere and ocean–atmosphere exchanges that would otherwise occur. The inventory of nitrogen compounds in the polar ice sheets is approximately 260 Tg N, dominated by nitrate in the much larger Antarctic ice sheet.

Antarctic ice sheet response to sudden and sustained ice-shelf collapse (ABUMIP)
Journal of Glaciology, 2020 Antarctica's ice shelves modulate the grounded ice flow, and weakening of ice shelves due to climate forcing will decrease their ‘buttressing’ effect, causing a response in the grounded ice.

A new approach to estimate ice dynamic rates using satellite observations in East Antarctica [PDF]
The Cryosphere, 2017 Mass balance changes of the Antarctic ice sheet are of significant interest due to its sensitivity to climatic changes and its contribution to changes in global sea level. While regional climate models successfully estimate mass input due to snowfall,

Environmental Research Letters, 2020 Prior studies have shown that above-normal sea surface temperatures (SSTs) enhance snowfall over Korea. Here, we show that heavy snow is also associated with below-normal East Sea SSTs, and we investigate the dynamical response of the atmosphere to this ...

Antarctic Ice Sheet paleo-constraint database [PDF]
Earth System Science Data, 2023 We present a database of observational constraints on past Antarctic Ice Sheet changes during the last glacial cycle intended to consolidate the observations that represent our understanding of past Antarctic changes and for state-space estimation and ...
