Antarctic sea ice over the past 130 000 years – Part 2: A review of its role in the Earth system

Abstract. Antarctic sea-ice cover reached historically low levels in 2023, consistent with the simulated decrease in sea-ice extent in response to anthropogenic warming. Antarctic sea ice is closely linked to multiple components of the Earth system, thus its demise could precipit...

Gravity topography modeling of the Denman Glacier region using a geostatistical approach

The Denman Glacier is one of East Antarctica's most dynamic outlet systems and is modeled to host the deepest continental marine trough, with the potential to contribute up to ∼ 1.5 m of global sea level rise. Yet its bed geometry remains poorly constrained because airborne radar...

Committed Antarctic Ice Sheet mass loss by the end of the twenty-first century

Abstract The Antarctic Ice Sheet is the largest source of uncertainty in sea-level rise projections, with uncertainties propagating through emissions scenarios, atmosphere–ocean general circulation models, ice-sheet dynamics and sea-level physics. In ice-sheet model intercomparis...

Reassessing the Role of the Antarctic Slope Current in Poleward Ocean Heat Transport

Abstract The Antarctic Slope Current (ASC) is often considered a barrier to the poleward transport of Circumpolar Deep Water (CDW), yet its vast extent has hindered circumpolar analysis of this relationship. Here, we use a high‐resolution global ocean‐sea ice model that resolves...
