The Arctic and Antarctic: two faces of climate change
Although both the Arctic and Antarctic are subject to a similar annual cycle of solar radiation and the same increasing greenhouse gas concentrations, over the previous two decades the two […]

Age, geographical distribution and taphonomy of an unusual occurrence of mummified crabeater seals on James Ross Island, Antarctica
Read more of: Age, geographical distribution and taphonomy of an unusual occurrence of mummified crabeater seals on James Ross Island, AntarcticaAn unusually dense collection of some 150 dead crabeater seals (Family Phocidae), in various stages of decay, occurs in the Brandy Bay hinterland, north-western James Ross Island, northern Antarctic Peninsula.

Contrasts in hydrology between regions of basal deformation and sliding beneath Rutford Ice Stream, West Antarctica, mapped using radar and seismic data
Read more of: Contrasts in hydrology between regions of basal deformation and sliding beneath Rutford Ice Stream, West Antarctica, mapped using radar and seismic data[1] Spatially coincident radar and seismic data collected two weeks apart on Rutford Ice Stream were analyzed to investigate the mechanical and hydrological characteristics of the ice-bed interface. Seismic data […]

Recent accumulation variability and change on the Antarctic Peninsula from the ERA40 reanalysis
Read more of: Recent accumulation variability and change on the Antarctic Peninsula from the ERA40 reanalysisThe Antarctic Peninsula has displayed significant climate change over recent decades. Understanding contemporaneous changes in accumulation is made difficult because the region’s complex orography means that ice-core data are not […]

A survey of Galileo plasma wave instrument observations of Jovian whistler-mode chorus
Read more of: A survey of Galileo plasma wave instrument observations of Jovian whistler-mode chorusA survey of plasma wave observations at Jupiter obtained by the plasma wave instrument on board the Galileo spacecraft is presented. The observations indicate that chorus emissions are observed commonly […]

West Antarctic Peninsula sea ice in 2005: extreme ice compaction and ice edge retreat due to strong anomaly with respect to climate
Read more of: West Antarctic Peninsula sea ice in 2005: extreme ice compaction and ice edge retreat due to strong anomaly with respect to climateIn September-October 2005, the juxtaposition of low-and high-pressure anomalies at 130 degrees W and 60 degrees W, respectively, created strong and persistent northerly airflow across the West Antarctic Peninsula (WAP).

Ocean biogeochemical response to phytoplankton-light feedback in a global model
Read more of: Ocean biogeochemical response to phytoplankton-light feedback in a global modelOceanic phytoplankton, absorbing solar radiation, can influence the bio-optical properties of seawater and hence upper ocean physics. We include this process in a global ocean general circulation model (OGCM) coupled […]

Antarctic sea ice thickness and snow-to-ice conversion from atmospheric reanalysis and passive microwave snow depth
Read more of: Antarctic sea ice thickness and snow-to-ice conversion from atmospheric reanalysis and passive microwave snow depthPassive microwave snow depth, ice concentration, and ice motion estimates are combined with snowfall from the European Centre for Medium-Range Weather Forecasting (ECMWF) reanalysis (ERA-40) from 1979-2001 to estimate the […]
