Year-round spatial segregation and fisheries overlap of white-chinned petrels from multiple populations at South Georgia
Read more of: Year-round spatial segregation and fisheries overlap of white-chinned petrels from multiple populations at South GeorgiaBy-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 […]

Interpreting the Altimetric Radar Cross Section of Young Sea Ice
Read more of: Interpreting the Altimetric Radar Cross Section of Young Sea IceKu-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 […]

Study of Drivers of Antarctic Weather Extremes
Read more of: Study of Drivers of Antarctic Weather ExtremesOver 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 […]

Dynamic instability of the Wilkes Subglacial Basin Ice Sheet, East Antarctica
Read more of: Dynamic instability of the Wilkes Subglacial Basin Ice Sheet, East AntarcticaThe 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 […]

No longer polar opposites: the Arctic and the Antarctic are converging towards a seasonally dominated sea-ice regime
Read more of: No longer polar opposites: the Arctic and the Antarctic are converging towards a seasonally dominated sea-ice regimeOver 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 […]

A near miss: invasive non-indigenous mussels and barnacles transported deep into Antarctic waters [short note]
Read more of: 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 […]

Inside-outward breakup of sea ice by locally generated waves in the Vincennes Bay Polynya
Read more of: Inside-outward breakup of sea ice by locally generated waves in the Vincennes Bay PolynyaCoastal 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 […]

Firn Capacity of Antarctic Ice Shelves via Satellites Observations
Read more of: Firn Capacity of Antarctic Ice Shelves via Satellites ObservationsWhat FIRN-CAISSO does This project maps how much of Antarctica’s ice shelf “sponge” (firn) remains, so we can better predict which shelves are most at risk of contributing to future […]
