The Last Scottish Ice Sheet [PDF]

Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 2018
ABSTRACTThe last Scottish Ice Sheet (SIS) expanded from a pre-existing ice cap after ∼35 ka. Highland ice dominated, with subsequent build-up of a Southern Uplands ice mass. The Outer Hebrides, Skye, Mull, the Cairngorms and Shetland supported persistent independent ice centres.

Large-ensemble simulations of the North American and Greenland ice sheets at the Last Glacial Maximum with a coupled atmospheric general circulation–ice sheet model [PDF]

Climate of the Past
The Last Glacial Maximum (LGM) was characterised by huge ice sheets covering the Northern Hemisphere, especially over North America, and by its cold climate.

An improved Antarctic dataset for high resolution numerical ice sheet models (ALBMAP v1) [PDF]

Earth System Science Data, 2010
The dataset described in this paper (ALBMAP) has been created for the purposes of high-resolution numerical ice sheet modelling of the Antarctic Ice Sheet. It brings together data on the ice sheet configuration (e.g.

Simulating the Early Holocene demise of the Laurentide Ice Sheet with BISICLES (public trunk revision 3298) [PDF]

Geoscientific Model Development, 2020
Simulating the demise of the Laurentide Ice Sheet covering Hudson Bay in the Early Holocene (10–7 ka) is important for understanding the role of accelerated changes in ice sheet topography and melt in the 8.2 ka event, a century long ...

Ice Streams of the Laurentide Ice Sheet [PDF]

Géographie physique et Quaternaire, 2006
Ice streams had a major influence on the configuration and the stability of the Laurentide Ice Sheet. Their identification is crucial for an understanding of ice sheet behaviour and their importance is reflected by the recent increase in paleo-ice stream research.

Firn on ice sheets

Nature Reviews Earth & Environment
Most of the Greenland and Antarctic ice sheets are covered with firn — the transitional material between snow and glacial ice. Firn is vital for understanding ice-sheet mass balance and hydrology, and palaeoclimate. In this Review, we synthesize knowledge of firn, including its formation, observation, modelling and relevance to ice sheets.

The Scandinavian Ice-Sheet [PDF]

Nature, 1894
IN reply to the letter of Prof. T. G. Bonney (NATURE, vol. xlix. p. 338), which I by chance have read to-day, concerning the difficulty of explaining how the Scandinavian land-ice could have crossed the deep channel of Skagerak and Kattegat, and have reached the East Anglian coasts, I should like to remark that this difficulty is not new to me, and ...

Interactions between topographically and thermally forced stationary waves: implications for ice-sheet evolution [PDF]

Tellus: Series A, Dynamic Meteorology and Oceanography, 2012
This study examines mutual interactions between stationary waves and ice sheets using a dry atmospheric primitive-equation model coupled to a three-dimensional thermomechanical ice-sheet model.

Data assimilation and prognostic whole ice sheet modelling with the variationally derived, higher order, open source, and fully parallel ice sheet model VarGlaS [PDF]

The Cryosphere, 2013
We introduce a novel, higher order, finite element ice sheet model called VarGlaS (Variational Glacier Simulator), which is built on the finite element framework FEniCS.

Last deglaciation of northern continental Europe

Cuadernos de Investigación Geográfica, 2015
Correlation of main ice sheet limits in northern continental Europe during Late Weichselian is presented, based on available data concerning occurrence of ice-marginal formations and their radiometric dating.
