1. Solar influences on polar modes of variability

   We present a multiple regression analysis of time series of the leading modes of variability in high latitudes, the Northern and Southern Annular Modes (NAM and SAM). The potential forcing […]

2. Atmospheric circulation impacts on winter maximum sea ice extent in the west Antarctic Peninsula region (1979-2001)

   Increasing evidence exists that the strong warming of the West Antarctic Peninsula (WAP) region since the 1950s is related to reduced sea ice that is likely to be due to […]

3. ASIRAS airborne radar resolves internal annual layers in the dry-snow zone of Greenland

   We present data from the European Space Agency’s Airborne SAR/Interferometric Radar Altimeter System (ASIRAS), flown during the CryoVex 2004 field calibration/validation campaign, and new, high-resolution depth profiles of snow density […]

4. Vegetation cover in a warmer world simulated using a dynamic global vegetation model for the mid Pliocene

   In this study we employ the TRIFFID (Top-down Representation of Interactive Flora and Foliage Including Dynamics) Dynamic Global Vegetation Model (DGVM) and the Hadley Centre Atmospheric General Circulation Model version […]

5. Miocene reversal of bottom water flow along the Pacific margin of the Antarctic Peninsula: stratigraphic evidence from a contourite sedimentary tail

   A Fossil Mounded Sedimentary Body (MB) has been identified in the sedimentary record on the central continental rise west of Adelaide Island, on the Antarctic Peninsula Pacific margin. The growth […]

6. Mean winds and tides in the mesosphere and lower thermosphere above Halley, Antarctica

   An imaging Doppler interferometer (IDI) at Halley, Antarctica (76°S, 26°W) has been used to record near continuous mean winds in the mesosphere/lower thermosphere since December 1996. Monthly mean winds are […]

7. Contrasting population changes in sympatric penguin species in association with climate warming

   Climate warming and associated sea ice reductions in Antarctica have modified habitat conditions for some species. These include the congeneric Adélie, chinstrap and gentoo penguins, which now demonstrate remarkable population […]

8. Evidence for a lacustrine faunal refuge in the Larsemann Hills, East Antarctica, during the Last Glacial Maximum

   Aim There is no previous direct evidence for the occurrence of lacustrine refuges for invertebrate fauna in Antarctica spanning the Last Glacial Maximum (LGM). In the absence of verified LGM […]

9. Statistics of sporadic iron and relation to atmospheric dynamics

   At Rothera Research Station (67.3°S, 68.1°W), Antarctica, 296 h of day and nighttime Fe-Boltzmann temperature lidar data were accumulated in 2003. During this time, sporadic iron layers (FeS) were observed […]

10. Small basins in the Scotia Sea: the Eocene Drake Passage gateway

    After isostatic correction for their sedimentary fill, the depths of two small oceanic basins in the southern Scotia Sea suggest that both started to open in mid to late Eocene […]

11. Regional variations of mesospheric gravity-wave momentum flux over Antarctica

    Images of mesospheric airglow and radar-wind measurements have been combined to estimate the difference in the vertical flux of horizontal momentum carried by high-frequency gravity waves over two dissimilar Antarctic […]

12. Transport of antarctic krill (Euphausia superba) across the Scotia Sea. Part II: Krill growth and survival

    A time-dependent, size-structured, physiologically based krill growth model was used in conjunction with a circulation model to test the hypothesis that Antarctic krill (Euphausia superba) populations at South Georgia are […]
