Forty-six years of Greenland Ice Sheet mass balance from 1972 to 2018

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance We reconstruct the mass balance of the Greenland Ice Sheet for the past 46 years by comparing glacier ice discharge into the ocean with interior accumulation of snowfall from regional atmospheric climate models over 260 drainage basins.

The evolution of the Patagonian Ice Sheet from 35 ka to the present day (PATICE)

Earth-Science Reviews, 2020
We present PATICE, a GIS database of Patagonian glacial geomorphology and recalibrated chronostratigraphic data. PATICE includes 58,823 landforms and 1,669 ages, and extends from 38°S to 55°S in southern South America.

Dynamic ice loss from the Greenland Ice Sheet driven by sustained glacier retreat

Communications Earth & Environment, 2020
The Greenland Ice Sheet is losing mass at accelerated rates in the 21st century, making it the largest single contributor to rising sea levels. Faster flow of outlet glaciers has substantially contributed to this loss, with the cause of speedup, and ...

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).

Quantitative sub-ice and marine tracing of Antarctic sediment provenance (TASP v1.0) [PDF]

Geoscientific Model Development
Ice sheet models should be able to accurately simulate palaeo ice sheets to have confidence in their projections of future polar ice sheet mass loss and resulting global sea level rise.

The future sea-level contribution of the Greenland ice sheet: a multi-model ensemble study of ISMIP6

The Cryosphere, 2020
. The Greenland ice sheet is one of the largest contributors to global mean sea-level rise today and is expected to continue to lose mass as the Arctic continues to warm.

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 theoretical steady state profile of ice sheets (two-dimentional model)

Antarctic Record, 1977
The Nye's kinematic theory of ice sheet profiles is revised on the basis of the conservation law of ice mass, because the Nye's ice sheet model or the revised Haefeli's model does not satisfy the ice mass conservation law and therefore they cannot have a

Research progress in geophysical exploration of the Antarctic ice sheet

Earthquake Research Advances, 2023
The Antarctic ice sheet is an important target of Antarctic research. Thickness and structure, including intraice and subice, are closely related to the mass balance of the ice sheet, and play an important role in the study of global sea level and ...
