1. A review of sea ice proxy information from polar ice cores

   Sea ice plays an important role in Earth’s climate system. The lack of direct indications of past sea ice coverage, however, means that there is limited knowledge of the sensitivity […]

2. Geomorphic signature of Antarctic submarine gullies: Implications for continental slope processes

   Five quantitatively distinct gully types are identified on the Antarctic continental margin from swath bathymetric data of over 1100 individual features. The gullies differ in terms of length, width, depth, […]

3. Twentieth century North Atlantic jet variability

   Long records of the latitude and speed of the North Atlantic eddy-driven jet stream since 1871 are presented from the newly available Twentieth Century Reanalysis. These jet variations underlie the […]

4. Late Holocene ice-flow reconfiguration in the Weddell sector of West Antarctica

   Here we report Late Holocene ice sheet and grounding-line changes to the Weddell Sea sector of West Antarctica. Internal radio-echo layering within the Bungenstock Ice Rise, which comprises very slow-flowing […]

5. Late Quaternary environmental changes in Marguerite Bay, Antarctic Peninsula, inferred from lake sediments and raised beaches

   The Antarctic Peninsula is one of the fastest-warming regions on Earth, but its palaeoenvironmental history south of 63° latitude is relatively poorly documented, relying principally on the marine geological record […]

6. An interhemispheric comparison of GPS phase scintillation with auroral emission observed at South Pole and from DMSP satellite

   The global positioning system (GPS) phase scintillation caused by high-latitude ionospheric irregularities during an intense high-speed stream (HSS) of the solar wind from April 29 to May 5, 2011, was […]

7. A spatiotemporal analysis of U.S. station temperature trends over the last century

   This study presents a nonlinear spatio-temporal analysis of 1167 station temperature records from the United States Historical Climatology Network covering the period from 1898 through 2008. We use the Empirical […]

8. Biological processes on glacier and ice sheet surfaces

   Glaciers and ice sheets are melting in response to climate warming. Whereas the physical behaviour of glaciers has been studied intensively, the biological processes associated with glaciers and ice sheets […]

9. Late Holocene changes in precipitation in northwest Tasmania and their potential links to shifts in the Southern Hemisphere westerly winds

   Accurate projections of future climate changes in regions susceptible to drought depend on a good understanding of past climate changes and the processes driving them. In the absence of longer […]

10. A marine diatom record from the Amundsen Sea — Insights into oceanographic and climatic response to the Mid-Pleistocene Transition in the West Antarctic sector of the Southern Ocean

    The goal of this study is to assess the changes that have occurred during the Mid-Pleistocene Transition, an important transitional period in cryosphere evolution, by examining the siliceous microfossil record […]

11. Publications and theses on Antarctic and sub-Antarctic birds, 1999

    A total of 138 scientific publications and theses on Antarctic and sub-Antarctic birds for 1999 is listed by author. This annual list is produced on behalf of the Bird Biology […]

12. Climate-induced change in biogenic bromine emissions from the Antarctic marine biosphere

    Climate change and human activities are expected to have a major impact on the structure and functioning of marine ecosystems and the biogeochemical cycles they mediate in the coming years. […]
