1. The Dufek and Forrestal intrusions, Antarctica: a centre for Ferrar Large Igneous Province dike emplacement?

   Newly acquired aeromagnetic data indicate the presence of a dike swarm that may have acted as a magma transport and feeder system from the plume impact site up to 3,500 […]

3. Large-scale geomagnetic effects of May 4, 1998

   We study large-scale magnetospheric disturbances elicited by the May4, 1998 high speed stream by modeling the Dst and studying records from 4 meridional magnetometer chains covering key local time sectors. […]

4. Power to the magnetosphere: May 4, 1998

   An extraordinary powering of the magnetosphere by the solar wind occurred in a 3-hour burst early on May 4 when the IMF was very intense and pointed south (≈-35 nT; […]

5. Supraglacial debris along the front of the Larsen-A Ice Shelf, Antarctic Peninsula

   Semi-continuous, linear accumulations of poorly-sorted debris are present on the surface of the remnant Larsen-A Ice Shelf, Antarctic Peninsula. These accumulations form a complex of debris bands extending parallel to […]

6. Rapid, large-scale temperature changes in the polar mesosphere and their relationship to meridional flows

   Mesospheric temperatures derived from spectroscopic measurements of the hydroxyl (OH) nightglow have been observed from Rothera (67.6°S, 68.1°W) and Halley (75.6°S, 26.6°W) stations in Antarctica during the 2002 austral winter […]

8. Astrobiological instrumentation for Mars – the only way is down

   In this paper, in this edition of the Journal commemorating the life and work of David Wynn-Williams, we consider approaches to the astrobiological investigation of Mars. We provide a brief […]

9. Why Raman spectroscopy on Mars? – a case of the right tool for the right job

   We provide a scientific rationale for the astrobiological investigation of Mars. We suggest that, given practical constraints, the most promising locations for the search for former life on Mars are […]

10. The human exploration of the Martian poles Part 2 – support technologies

    In Part 1 of this paper, we presented a phased approach to the development of a Mars pole human-inhabited research station modelled on those in the terrestrial polar regions. To […]

11. Fourier-transform Raman spectroscopic studies of chronological change in stromatolitic cores from Antarctic lake sediments

    The Fourier transform-Raman spectra of two lacustrine sediment cores from Antarctic sites are reported. The Lake Hoare specimens were predominantly calcium carbonate, quartz and β-carotene, with chlorophyll and calcium sulphate […]

12. Non-destructive analysis of pigments and other organic compounds in lichens using Fourier-transform Raman spectroscopy: a study of Antarctic epilithic lichens

    Lichens in Antarctic habitats are subjected to environmental extremes, including UVB radiation, desiccation and low temperatures, as well as to rapid fluctuations in these. Lichens synthesise a variety of chemical […]
