Evolution of the Southern Annular Mode during the past millennium
Read more of: Evolution of the Southern Annular Mode during the past millenniumThe Southern Annular Mode (SAM) is the primary pattern of climate variability in the Southern Hemisphere1, 2, influencing latitudinal rainfall distribution and temperatures from the subtropics to Antarctica. The positive […]

New constraints on the timing of West Antarctic ice sheet retreat in the eastern Amundsen Sea since the Last Glacial Maximum
Read more of: New constraints on the timing of West Antarctic ice sheet retreat in the eastern Amundsen Sea since the Last Glacial MaximumGlaciers flowing into the Amundsen Sea Embayment (ASE) account for > 35% of the total discharge of the West Antarctic Ice Sheet (WAIS) and have thinned and retreated dramatically over […]

Ancient pre-glacial erosion surfaces preserved beneath the West Antarctic Ice Sheet
Read more of: Ancient pre-glacial erosion surfaces preserved beneath the West Antarctic Ice SheetWe present ice-penetrating radar evidence for ancient (pre-glacial) and extensive erosion surfaces preserved beneath the upstream Institute and Möller ice streams, West Antarctica. Radar data reveal a smooth, laterally continuous, […]

An assessment of the use of ocean gliders to undertake acoustic measurements of zooplankton: the distribution and density of Antarctic krill (Euphausia superba) in the Weddell Sea
Read more of: An assessment of the use of ocean gliders to undertake acoustic measurements of zooplankton: the distribution and density of Antarctic krill (Euphausia superba) in the Weddell SeaA calibrated 120 kHz single-beam echo-sounder was integrated into an ocean glider and deployed in the Weddell Sea, Southern Ocean. The glider was deployed for two short periods in January […]

The seasonality of Antarctic sea ice trends
Read more of: The seasonality of Antarctic sea ice trendsAntarctic sea ice is experiencing a weak overall increase in area that is the residual of opposing regional trends. This study considers their seasonal pattern. In addition to traditional ice […]

Iodine in Sea Ice and the Polar Atmosphere
Read more of: Iodine in Sea Ice and the Polar AtmosphereThe volatilisation of iodine from the ocean and release to the atmosphere in the ice-covered polar regions has been studied. Laboratory experiments involving sea ice- and ice associated- diatoms have […]

Global climate impacts from changes in Antarctic Intermediate Water
Read more of: Global climate impacts from changes in Antarctic Intermediate WaterObservations suggest that properties of Antarctic Intermediate Water (AAIW) are changing. An understanding of how changes in the ocean may interact with the atmosphere is crucial for understanding how Earth’s […]

Molecular analysis of the cold tolerant Antarctic nematode, Panagrolaimus davidi
Read more of: Molecular analysis of the cold tolerant Antarctic nematode, Panagrolaimus davidiIsolated and established in culture from the Antarctic in 1988, the nematode Panagrolaimus davidi has proven to be an ideal model for the study of adaptation to the cold. Not […]

Seaweed biodiversity in the south-western Antarctic Peninsula: Surveying macroalgal community composition in the Adelaide Island / Marguerite Bay region over a 35-year time span
Read more of: Seaweed biodiversity in the south-western Antarctic Peninsula: Surveying macroalgal community composition in the Adelaide Island / Marguerite Bay region over a 35-year time spanThe diversity of seaweed species of the south-western Antarctic Peninsula region is poorly studied, contrasting with the substantial knowledge available for the northern parts of the Peninsula. However, this is […]

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum
Read more of: Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial MaximumThis paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to […]

An algorithm for approximating the L * invariant coordinate from the real-time tracing of one magnetic field line between mirror points
Read more of: An algorithm for approximating the L * invariant coordinate from the real-time tracing of one magnetic field line between mirror pointsThe L * invariant coordinate depends on the global electromagnetic field topology at a given instance and the standard method for its determination requires a computationally expensive drift contour tracing. This […]
