Ice stream activity scaled to ice sheet volume during Laurentide Ice Sheet deglaciation [PDF]
Nature, 2016 The contribution of the Greenland and West Antarctic ice sheets to sea level has increased in recent decades, largely owing to the thinning and retreat of outlet glaciers and ice streams. This dynamic loss is a serious concern, with some modelling studies suggesting that the collapse of a major ice sheet could be imminent or potentially underway in ...

How might the North American ice sheet influence the northwestern Eurasian climate? [PDF]
Climate of the Past, 2015 It is now widely acknowledged that past Northern Hemisphere ice sheets covering Canada and northern Europe at the Last Glacial Maximum (LGM) exerted a strong influence on climate by causing changes in atmospheric and oceanic circulations.

A rapidly converging initialisation method to simulate the present-day Greenland ice sheet using the GRISLI ice sheet model (version 1.3) [PDF]
Geoscientific Model Development, 2019 Providing reliable projections of the ice sheet contribution to future sea-level rise has become one of the main challenges of the ice sheet modelling community.

Investigating the local-scale influence of sea ice on Greenland surface melt [PDF]
The Cryosphere, 2017 Rapid decline in Arctic sea ice cover in the 21st century may have wide-reaching effects on the Arctic climate system, including the Greenland ice sheet mass balance. Here, we investigate whether local changes in sea ice around the Greenland ice sheet

Thermomechanical modelling of the Scandinavian ice sheet: implications for ice-stream formation [PDF]
, 1999 This work attempts to explain the fan-like landform assemblages observed in satellite images of the area covered by the former Scandinavian ice sheet (SIS). These assemblages have been interpreted as evidence of large ice streams within the SIS.

Frontiers in Earth Science, 2019 On April 7, 2016 the Nansen ice shelf (NIS) front calved into two icebergs, the first large-scale calving event in >30 years. Three hydrophone moorings were deployed seaward of the NIS in December 2015 and over the following months recorded hundreds ...

ICESHEET 1.0: a program to produce paleo-ice sheet reconstructions with minimal assumptions [PDF]
Geoscientific Model Development, 2016 We describe a program that produces paleo-ice sheet reconstructions using an assumption of steady-state, perfectly plastic ice flow behaviour. It incorporates three input parameters: ice margin, basal shear stress and basal topography.

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

Tracer transport in an isochronal ice-sheet model
Journal of Glaciology, 2017 The full history of ice sheet and climate interactions is recorded in the vertical profiles of geochemical tracers in polar ice sheets. Numerical simulations of these archives promise great advances both in the interpretation of these reconstructions and

Emergence of the Shackleton Range from beneath the Antarctic Ice Sheet due to glacial erosion [PDF]
, 2014 This paper explores the long-term evolution of a subglacial fjord landscape in the Shackleton Range, Antarctica. We propose that prolonged ice-sheet erosion across a passive continental margin caused troughs to deepen and lower the surrounding ice-sheet ...
