1. An initial assessment of Antarctic Sea ice extent in the CMIP5 models

   This paper examines the annual cycle and trends in Antarctic sea ice extent (SIE) for 18 models used in phase 5 of the Coupled Model Intercomparison Project (CMIP5) that were […]

2. Geomagnetic activity signatures in wintertime stratosphere wind, temperature, and wave response

   We analyzed ERA-40 and ERA Interim meteorological re-analysis data for signatures of geomagnetic activity in zonal mean zonal wind, temperature, and Eliassen-Palm flux in the Northern Hemisphere extended winter (November–March). […]

3. Environmental management of a scientific field camp in Maritime Antarctica: reconciling research impacts with conservation goals in remote ice-free areas

   Currently, a substantial proportion of Antarctic research is carried out through deployment of field camps, but little detailed information on the running of these facilities is often available. The remoteness […]

4. UK Antarctic Place-names Committee website

   The UK-Antarctic Place-names Committee website gives users access to the UK Antarctic Gazetteer through a web-map interface. This has been completely rebuilt in 2012-13 using up-to-date Open Source systems. Access […]

5. SCAR Antarctic Digital Database V 6.0

   The SCAR Antarctic Digitial database (ADD) is a seamless, multi-scale compilation of the best international topographic mapping for Antarctica. It is managed and developed by BAS on behalf of SCAR. […]

6. Computer animation of bathymetry around Orkney Passage, Southern Ocean

   This is a short video animation of a “flythrough” of Orkney Passage, between the Weddell and Scotia Seas, using multi-beam sonar and satellite gravity-based measurements. Much of the sonar data […]

7. The freshwater system west of the Antarctic Peninsula: spatial and temporal changes

   Climate change west of the Antarctic Peninsula is the most rapid of anywhere in the Southern Hemisphere, with associated changes in the rates and distributions of freshwater inputs to the […]

8. Changes in the metastability of the midlatitude Southern Hemisphere circulation and the utility of nonstationary cluster analysis and split-flow blocking indices as diagnostic tools

   Changes in the metastability of the Southern Hemisphere 500-hPa circulation are examined using both cluster analysis techniques and split-flow blocking indices. The cluster methodology is a purely data-driven approach for […]

9. Dense bottom layers in the Scotia Sea, Southern Ocean: Creation, lifespan, and destruction

   The lower limb of the Atlantic overturning circulation is renewed by dense waters from the Southern Ocean, a substantial portion of which flow through the Scotia Sea. We report dense […]

10. A model reconstruction of the Antarctic sea ice thickness and volume changes over 1980–2008 using data assimilation

    Sea ice variability in the Southern Ocean has a complex spatio-temporal structure. In a global warming context, the Antarctic sea ice cover has slightly expanded over the recent decades. This […]

11. First geomorphological record and glacial history of an inter-ice stream ridge on the West Antarctic continental shelf

    Inter-ice stream areas cover significant portions of Antarctica’s formerly glaciated shelves, but have been largely neglected in past geological studies because of overprinting by iceberg scours. Here, we present results […]

12. The spatial scale of ozone depletion events derived from an autonomous surface ozone network in coastal Antarctica

    To probe the spatial extent of tropospheric ozone depletion events during Antarctic spring, a network of 10 autonomous ozone monitors was established around the Dronning Maud Land sector of Antarctica […]
