West Antarctic ice sheet dynamics

Eos, Transactions American Geophysical Union, 1985
Mercer [1978] pointed out that a climatic warming, caused, for instance, by an increasing atmospheric CO2 concentration, may lead to a very rapid deglaciation (within a few hundred years) of the West Antarctic Ice Sheet, resulting in a sea level rise of about 5 m.

Antarctic Ice Sheet and Radar Altimetry: A Review [PDF]

Remote Sensing, 2009
Altimetry is probably one of the most powerful tools for ice sheet observation. Our vision of the Antarctic ice sheet has been deeply transformed since the launch of the ERS1 satellite in 1991. With the launch of ERS2 and Envisat, the series of altimetric observations now provides 19 years of continuous and homogeneous observations that allow ...

Coupling framework (1.0) for the Úa (2023b) ice sheet model and the FESOM-1.4 z-coordinate ocean model in an Antarctic domain [PDF]

Geoscientific Model Development
The rate at which the Antarctic ice sheet loses mass is to a large degree controlled by ice–ocean interactions underneath small ice shelves, with the most sensitive regions concentrated in even smaller areas near grounding lines and local pinning points.

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 ...

History of oceanic front development in the New Zealand sector of the Southern Ocean during the Cenozoic--a synthesis [PDF]

, 2001
The New Zealand sector of the Southern Ocean (NZSSO) has opened about the Indian-Pacific spreading ridge throughout the Cenozoic. Today the NZSSO is characterised by broad zonal belts of antarctic (cold), subantarctic (cool), and subtropical (warm ...

ENSO‐Mediated Linkage Between the East Asian Summer Monsoon and Cordilleran Ice Sheet Discharge During MIS 3

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)

Ice cores and SeaRISE: What we do (and don't) know [PDF]

Ice core analyses are needed in SeaRISE to learn what the West Antarctic ice sheet and other marine ice sheets were like in the past, what climate changes led to their present states, and how they behave.

Dissolved Black Carbon in North Cascades Snow, Meltwater and a Downstream River

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Quantification of black carbon on snow in the Cascade Range is needed due to increasing wildfire intensity and frequency. Here, the benzenepolycarboxylic acid (BPCA) molecular method was used to measure dissolved black carbon (DBC) in snow, nearby rivers, streams, and supraglacial melt collected in 2022 and 2023 from Mount Baker and Mount ...

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.

Understanding Aitken Mode Aerosol Variability Over the Southern Ocean and Antarctica: Insights From Cloud Condensation Nuclei Data

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Aitken mode aerosol particles can influence cloud properties and lifetime by acting as a reservoir of potential cloud condensation nuclei (CCN) that can replenish the CCN population against precipitation scavenging. However, data on Aitken‐mode aerosols in remote regions are limited. In this study, we developed a method to estimate Aitken mode
