Modelling diatom responses to climate induced fluctuations in the moisture balance in continental Antarctic lakes
Read more of: Modelling diatom responses to climate induced fluctuations in the moisture balance in continental Antarctic lakesThe water chemistry of lake systems on the edge of the Antarctic continent responds quickly to changes in the moisture balance. This is expressed as increasing salinity and decreasing lake […]

Dynamic seasonal cycling of inorganic carbon downstream of South Georgia, Southern Ocean
Read more of: Dynamic seasonal cycling of inorganic carbon downstream of South Georgia, Southern OceanThe influence of the island mass effect of South Georgia on the seasonal marine carbon cycle was investigated during austral summer (January–February) 2008. South Georgia (54–55°S 36–38°W) lies on the […]

DISCOVERY 2010: Spatial and temporal variability in a dynamic polar ecosystem
Read more of: DISCOVERY 2010: Spatial and temporal variability in a dynamic polar ecosystemThe Scotia Sea has been a focus of biological- and physical oceanographic study since the Discovery expeditions in the early 1900s. It is a physically energetic region with some of […]

Acoustic impedance and basal shear stress beneath four Antarctic ice streams
Read more of: Acoustic impedance and basal shear stress beneath four Antarctic ice streamsThe acoustic impedance of the subglacial material beneath 7.2 km profiles on four ice streams in Antarctica has been measured using a seismic technique. The ice streams span a wide […]

Recent rapid regional climate warming on the Antarctic Peninsula
Read more of: Recent rapid regional climate warming on the Antarctic PeninsulaThe Intergovernmental Panel on Climate Change (IPCC) confirmed that mean global warming was 0.6 +/- 0.2degreesC during the 20th century and cited anthropogenic increases in greenhouse gases as the likely […]

Ophiolite obduction pulses as a proxy indicator of superplume events?
Read more of: Ophiolite obduction pulses as a proxy indicator of superplume events?A major new synthesis of ophiolite geochronology and map of global Phanerozoic distribution indicates that previously noted pulses of ophiolite obduction can be linked to superplume-related tectonism. A marked cyclicity […]
