Greater Greenland Ice Sheet contribution to global sea level rise in CMIP6

Nature Communications, 2020
The potential contribution of Greenland Ice Sheet to sea level rise in the future is known to be substantial. Here, the authors undertake new modelling showing that the Greenland Ice Sheet sea level rise contribution is 7.9 cm more using the CMIP6 SSP585

The Glimmer community ice sheet model [PDF]

Journal of Geophysical Research: Earth Surface, 2009
We present a detailed description of the Glimmer ice sheet model, comprising the physics represented in the model and the numerical techniques used. Established methods are combined with good software design to yield an adaptable and widely applicable model. A flexible framework for coupling Glimmer to global climate forcing is also described.

Modelling Glaciers in the HARMONIE-AROME NWP model [PDF]

Advances in Science and Research, 2017
HARMONIE-AROME is a convection-permitting non-hydrostatic model that includes the multi-purpose SURFEX surface model. It is developed for high resolution (1–3 km) weather forecasting and applied in a number of regions in Europe and the Mediterranean ...

Modeling Antarctic ice sheet loss [PDF]

Science, 2019
Cryosphere Knowledge of the speed and scale of ice-shelf melting in Antarctica is crucial for estimates of ice sheet loss. How accurate do models need to be to capture these processes and yield useful projections of future ice sheet loss and the resulting sea level rise? To address this question, Goldberg et al.

Antarctic ice sheet and oceanographic response to eccentricity forcing during the early Miocene [PDF]

Climate of the Past, 2011
Stable isotope records of benthic foraminifera from ODP Site 1264 in the southeastern Atlantic Ocean are presented which resolve the latest Oligocene to early Miocene (~24–19 Ma) climate changes at high temporal resolution (<3 kyr).

Evaluating an accelerated forcing approach for improving computational efficiency in coupled ice sheet–ocean modelling [PDF]

Geoscientific Model Development
Coupled ice sheet–ocean models are increasingly being developed and applied to important questions pertaining to processes at the Greenland and Antarctic Ice Sheet margins, which play a pivotal role in ice sheet stability and sea level rise projections.

Modeling the Cordilleran Ice Sheet [PDF]

Géographie physique et Quaternaire, 2007
A time-dependent ice flow model is used to provide detailed reconstructions of ice growth and retreat for the southern portion of the Late Wisconsinan Cordilleran Ice Sheet. The two-dimensional, time-dependent model provides ice surface elevations and flow directions at a grid spacing of 15 km.

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.

Comparison of calibration methods of a PICO basal ice shelf melt module implemented in the GRISLI v2.0 ice sheet model [PDF]

Geoscientific Model Development
Uncertainties in future sea level rise are mainly due to uncertainties in Antarctic ice sheet projections. Indeed, modelling the future of the Antarctic ice sheet presents many challenges.

Impact of ocean forcing on the Aurora Basin in the 21st and 22nd centuries

Annals of Glaciology, 2016
The grounded ice in the Totten and Dalton glaciers is an essential component of the buttressing for the marine-based Aurora basin, and hence their stability is important to the future rate of mass loss from East Antarctica. Totten and Vanderford glaciers
