Journal of Glaciology, 2017 Ice-shelf basal melting is the largest contributor to the negative mass balance of the Antarctic ice sheet. However, current implementations of ice/ocean interactions in ice-sheet models disagree with the distribution of sub-shelf melt and freezing rates

Sea-level response to ice sheet evolution: An ocean perspective [PDF]
The ocean's influence upon and response to Antarctic ice sheet changes is considered in relation to sea level rise over recent and future decades. Assuming present day ice fronts are in approximate equilibrium, a preliminary budget for the ice sheet is ...

Feedbacks between ice and ocean dynamics at the West Antarctic Filchner-Ronne Ice Shelf in future global warming scenarios [PDF]
, 2016 The ice flow at the margins of the West Antarctic Ice Sheet is moderated by large ice shelves. Their buttressing effect substantially controls the mass balance of the WAIS and thus its contribution to sea level rise.

Multianalytical provenance analysis of Eastern Ross Sea LGM till sediments (Antarctica): Petrography, geochronology, and thermochronology detrital data [PDF]
, 2017 In order to reveal provenance of detrital sediments supplied by West Antarctic Ice Sheet (WAIS), 19 glaciomarine cores of Last Glacial Maximum age were analyzed from Eastern Ross Sea and Sulzberger Bay.

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.

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Ongoing glacial isostatic adjustment (GIA) is detectable in geodetic height time series and changes in the temporal gravity field. Global GIA models are often used to remove these signals from data but quantifying the errors in such models is difficult due to insufficient knowledge of Earth rheology and past ice history.

An improved retrieval method for liquid water content of the Antarctic ice sheet using SMOS data
Geocarto InternationalWith global climate warming, Antarctic ice sheet melting has garnered increasing attention, as changes in liquid water content (LWC) significantly affect sea level rise and regional climate.

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Stable water isotopes from ice cores are a unique proxy for reconstructing polar climate variability. Their interpretation is, however, challenging due to the impact of depositional noise. Here, we analyze the centennial‐ to millennial‐scale isotope variability of the Greenland ice cores NGRIP, GRIP, and GISP2 to investigate how their coherent

Altimetry, gravimetry, GPS and viscoelastic modeling data for the joint inversion for glacial isostatic adjustment in Antarctica (ESA STSE Project REGINA) [PDF]
, 2018 The poorly known correction for the ongoing deformation of the solid Earth caused by glacial isostatic adjustment (GIA) is a major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry and to a ...

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract The Antarctic Slope Current (ASC) plays a crucial role in modulating the transport of warm Circumpolar Deep Water onto the continental shelves, influencing ice shelf melting and Antarctic ice sheet mass balance. However, our understandings of the ASC variability and its driving mechanisms remain limited due to observational constraints in the ...
