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 ...

The Mathematical Model of Ice Sheets and the Calculation of the Evolution of the Greenland Ice Sheet [PDF]

Journal of Glaciology, 1985
Abstract An evolutionary mathematical model of ice sheets is presented. The model takes into account the basic climatic and geophysical parameters, with temperature parameterization. Some numerical data derived from experiments on the Greenland ice sheet are received.

Evidence for the stability of the West Antarctic Ice Sheet divide for 1.4 million years [PDF]

, 2016
Past fluctuations of the West Antarctic Ice Sheet (WAIS) are of fundamental interest because of the possibility of WAIS collapse in the future and a consequent rise in global sea level.

Microbial nitrogen cycling on the Greenland Ice Sheet [PDF]

, 2012
Nitrogen inputs and microbial nitrogen cycling were investigated along a 79 km transect into the Greenland Ice Sheet (GrIS) during the main ablation season in summer 2010. The depletion of dissolved nitrate and production of ammonium (relative to icemelt)

The configuration of Northern Hemisphere ice sheets through the Quaternary

Nature Communications, 2019
How global climatic changes are translated into ice-sheet fluctuations and sea-level change is not well understood. Here the authors present a compilation of empirical data and numerical modelling results of pre-LGM Northern Hemisphere ice sheet changes ...

Ice flux evolution in fast flowing areas of the Greenland ice sheet over the 20th and 21st centuries

Journal of Glaciology, 2017
This study investigates the evolution of Greenland ice sheet flux focusing on five of the main fast flowing regions (Petermann glacier, North East Greenland Ice Stream, Kangerdlugssuaq glacier, Helheim glacier and Jakobshavn glacier) in response to 20th ...

Hysteresis of the Antarctic Ice Sheet With a Coupled Climate‐Ice‐Sheet Model

Geophysical Research Letters
AbstractThe stability of the Antarctic ice sheet under different fixed 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.

Global ice sheet modeling [PDF]

, 1994
The University of Maine conducted this study for Pacific Northwest Laboratory (PNL) as part of a global climate modeling task for site characterization of the potential nuclear waste respository site at Yucca Mountain, NV. The purpose of the study was to develop a global ice sheet dynamics model that will forecast the three-dimensional configuration of

Trimlines, blockfields and the vertical extent of the last ice sheet in southern Ireland [PDF]

, 2015
The research reported here was supported by UK NERC grant NER/B/S/2001/0919Trimlines separating glacially abraded lower slopes from blockfield-covered summits on Irish mountains have traditionally been interpreted as representing the upper limit of the ...

A model of the Antarctic Ice Sheet

Deep Sea Research Part B. Oceanographic Literature Review, 1982
Numerical modelling of ice sheets and glaciers has become a useful tool in glaciological research. A model described here deals with the vertical mean ice velocity, is time dependent, computes bedrock adjustment and uses an empirical diagnostic relationship to derive the distribution of ice thickness in ice shelves.
