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

   Antarctic sea-ice cover reached historically low levels in 2023, consistent with the simulated decline in sea-ice extent in response to anthropogenic warming. As Antarctic sea ice is closely linked to […]

2. Southern elephant seal population breeding probability declines with increased sea-ice cover in a key foraging region

   Regional differences in southern elephant seal (Mirounga leonina) population trends have long been hypothesised to reflect environmental variation affecting prey availability. By combining census counts, demographic data, and locally relevant […]

3. Temperature variation associated with interannual variability in abundance of juvenile Patagonian toothfish (Dissostichus eleginoides) at South Georgia

   A detailed understanding of the life cycles of fished species in relation to their environment is important for assessing the impacts of environmental change and informing fisheries management. Here, we […]

4. Year-round spatial segregation and fisheries overlap of white-chinned petrels from multiple populations at South Georgia

   By-catch in fisheries is the leading cause of population decline in pelagic sea-birds. The white-chinned petrel (Procellaria aequinoctialis) is the most by-caught sea-bird species in the Southern Ocean, and many […]

5. Interpreting the Altimetric Radar Cross Section of Young Sea Ice

   Ku-band radar altimeters such as the one onboard CryoSat-2 measure the return-time of backscattered radar pulses to derive sea ice freeboard and thickness. This method relies on the two-way penetration […]

6. Study of Drivers of Antarctic Weather Extremes

   Over Antarctica, short-lived extremes in wind, precipitation, and near-surface temperature influence surface mass balance by affecting snow accumulation, snow redistribution, meltwater production, and ice-shelf stability. This thesis uses a combination […]

7. Dynamic instability of the Wilkes Subglacial Basin Ice Sheet, East Antarctica

   The Wilkes Subglacial Basin (WSB), a marine-based sector of the East Antarctic Ice Sheet, contains enough ice to increase the global-mean sea level by 3–4 m. The geometry of the WSB […]

8. No longer polar opposites: the Arctic and the Antarctic are converging towards a seasonally dominated sea-ice regime

   Over the satellite period, Arctic and Antarctic sea ice extent seemed to follow opposite pathways. Arctic sea ice showed a strong and prolonged decrease until 2007 and then stalled in […]

11. A near miss: invasive non-indigenous mussels and barnacles transported deep into Antarctic waters [short note]

    The Southern Ocean around Antarctica remains the only large area on the planet populated by almost entirely native and mainly endemic species. Despite being one of the most constant environments […]

12. Inside-outward breakup of sea ice by locally generated waves in the Vincennes Bay Polynya

    Coastal polynyas are recurring regions of open water within sea ice that serve as sea-ice factories, producing vast amounts of new ice relative to nearby sea-ice-covered regions. Their formation and […]
