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...

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...

Search for sociality in white sharks: investigation of the co-occurrence of juvenile white sharks (Carcharodon carcharias) using passive acoustic telemetry data

Context Social network analysis (SNA) as a quantitative measure of animal grouping and social behaviours has been increasingly used to study the group dynamics and potential sociality of elasmobranch species. Aims Despite their mainly solitary swimming and hunting behaviours, whi...
