Remote Sensing, 2023 In polar regions, positive feedback of snow and ice albedo can intensify global warming. While recent significant decreases in Arctic surface ice albedo have drawn considerable attention, Antarctic surface albedo variability remains underexplored.

Modelling ice dynamic contributions to sea level rise from the Antarctic Peninsula [PDF]
, 2015 The future ice dynamical contribution to sea-level rise (SLR) from 210 ice shelf nourishing drainage basins of the Antarctic Peninsula Ice Sheet (APIS) is simulated, using the British Antarctic Survey Antarctic Peninsula Ice Sheet Model.

Did the West Antarctic Ice Sheet Create the East Antarctic Ice Sheet? [PDF]
Annals of Glaciology, 1982 The mostly terrestrial East Antarctic ice sheet is ten times larger and probably more stable than the mostly marine West Antarctic ice sheet. It is natural to suppose that the former appeared first, and that perhaps the latter was partially formed from an outflow of East Antarctic ice onto the West Antarctic continental shelf.

Physical processes and feedbacks obscuring the future of the Antarctic Ice Sheet
Geosystems and Geoenvironment, 2022 The Antarctic Ice Sheet holds a vital role in Earth's climate system and its changes have global implications for the climate, sea level, coastal ecosystems and population.

Antarctic subglacial hydrology: current knowledge and future challenges [PDF]
, 2014 Flood-carved landforms across the deglaciated terrain of Victoria Land, East Antarctica, provide convincing geomorphological evidence for the existence of subglacial drainage networks beneath the Antarctic ice sheet, and motivate research into the ...

Antarctic blue-ice moraines: Analogue for Northern Hemisphere ice sheets? [PDF]
Quaternary Science Reviews, 2020 Abstract This paper reviews the distribution, character and age of blue-ice moraines in Antarctica and asks whether there are implications for the study of former Pleistocene ice sheets in the Northern Hemisphere. Blue-ice forms where acceleration of downslope katabatic winds removes snow and causes ice to ablate.

Remote Sensing of Antarctic Glacier and Ice-Shelf Front Dynamics—A Review
Remote Sensing, 2018 The contribution of Antarctica’s ice sheet to global sea-level rise depends on the very dynamic behavior of glaciers and ice shelves. One important parameter of ice-sheet dynamics is the location of glacier and ice-shelf fronts.

Uncertainty quantification of the multi-centennial response of the Antarctic ice sheet to climate change [PDF]
The Cryosphere, 2019 Ice loss from the Antarctic ice sheet (AIS) is expected to become the major contributor to sea level in the next centuries. Projections of the AIS response to climate change based on numerical ice-sheet models remain challenging due to the complexity of ...

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 fertilises the Southern Ocean [PDF]
Biogeosciences, 2013 Abstract. Southern Ocean (SO) marine primary productivity (PP) is strongly influenced by the availability of iron in surface waters, which is thought to exert a significant control upon atmospheric CO2 concentrations on glacial/interglacial timescales. The zone bordering the Antarctic Ice Sheet exhibits high PP and seasonal plankton blooms in response ...
