1. Millennial timescale regeneration in a moss from Antarctica

   Mosses, dominant elements in the vegetation of polar and alpine regions, have well-developed stress tolerance features permitting cryptobiosis. However, direct regeneration after longer periods of cryptobiosis has been demonstrated only […]

2. Areas of importance for seabirds tracked from French southern territories, and recommendations for conservation

   Seabirds are increasingly threatened worldwide, with population declines for many species that are faster than in any other group of birds. Here the Important Bird Area (IBA) criteria recommended by […]

3. First optical observations of energetic electron precipitation at 4278 Å caused by a powerful VLF transmitter

   A summary is presented of experimental optical observations at 4278 Å from close to a powerful (~150 kW) VLF transmitter (call-sign JXN) with a transmission frequency of 16.4 kHz. Approximately […]

4. Terrestrial and submarine evidence for the extent and timing of the Last Glacial Maximum and the onset of deglaciation on the maritime-Antarctic and sub-Antarctic islands

   This paper is the maritime and sub–Antarctic contribution to the Scientific Committee for Antarctic Research (SCAR) Past Antarctic Ice Sheet Dynamics (PAIS) community Antarctic Ice Sheet reconstruction. The overarching aim […]

5. Biogeochemical responses to nutrient, moisture and temperature manipulations of soil from Signy Island, South Orkney Islands in the Maritime Antarctic

   We have investigated how the microbially-driven processes of carbon (C) mineralization (respiration) and nitrogen (N) mineralization/immobilization in a soil from the northern Maritime Antarctic respond to differences in water availability […]

6. Rates of warming and the global sensitivity of shallow water marine invertebrates to elevated temperature

   Assessing the sensitivity of ectotherms to variability in their environment is a key challenge, especially in the face of rapid warming of the Earth’s surface. Comparing the upper temperature limits […]

7. Glacial history of sub-Antarctic South Georgia based on the submarine geomorphology of its fjords

   We present multibeam swath bathymetric surveys of the major fjords surrounding the sub-Antarctic island of South Georgia to characterise the glacial geomorphology and to identify the relative timings and extent […]

8. Interaction strengths in balanced carbon cycles and the absence of a relation between ecosystem complexity and stability

   The strength of interactions is crucial to the stability of ecological networks. However, the patterns of interaction strengths in mathematical models of ecosystems have not yet been based upon independent […]

9. Reconstruction of changes in the Amundsen Sea and Bellingshausen Sea sector of the West Antarctic Ice Sheet since the Last Glacial Maximum

   Marine and terrestrial geological and marine geophysical data that constrain deglaciation since the Last Glacial Maximum (LGM) of the sector of the West Antarctic Ice Sheet (WAIS) draining into the […]

11. Geothermal activity helps life survive glacial cycles

    Climate change has played a critical role in the evolution and structure of Earth’s biodiversity. Geothermal activity, which can maintain ice-free terrain in glaciated regions, provides a tantalizing solution to […]

12. Minimal change in Antarctic Circumpolar Current flow speed between the last glacial and Holocene

    The Antarctic Circumpolar Current is key to the mixing and ventilation of the world’s oceans. This current flows from west to east between about 45° and 70°S connecting the Atlantic, […]
