1. 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. […]

2. 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 […]

3. 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 […]

4. 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 […]

5. 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 […]

6. 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 […]

7. 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 […]

8. 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 […]

9. At–sea behavior varies with lunar phase in a nocturnal pelagic seabird, the swallow-tailed gull

   Strong and predictable environmental variability can reward flexible behaviors among animals. We used long-term records of activity data that cover several lunar cycles to investigate whether behavior at-sea of swallow-tailed […]

11. BEDMAP2: Bedrock topography of Antarctica

    This map presents the final outputs from the BEDMAp2 project as a double-sided poster map.It shows the new BEDMAP datasets of Antarctic ice thickness, surface height and bed elevation mapped […]

12. Warm climate isotopic simulations: what do we learn about interglacial signals in Greenland ice cores?

    Measurements of Last Interglacial stable water isotopes in ice cores show that central Greenland d18O increased by at least 3& compared to present day. Attempting to quantify the Greenland interglacial […]
