1. Comparison of contemporary and fossil diatom assemblages from the western Antarctic Peninsula shelf

   During the past ten years, the Antarctic Peninsula has been identified as the most rapidly warming region of the Southern Hemisphere and it is important to place this warming in […]

2. Volcanic features and hydrological setting of Southern Thule, South Sandwich Islands

   This paper provides new observations of volcanic features and hydrological characteristics in and around Southern Thule, the southernmost group of islands in the South Sandwich Islands, including the first high-resolution […]

5. Reversible interconversion of carbon dioxide and formate by an electroactive enzyme

   Carbon dioxide (CO2) is a kinetically and thermodynamically stable molecule. It is easily formed by the oxidation of organic molecules, during combustion or respiration, but is difficult to reduce. The […]

6. Boundary layer physics over snow and ice

   Observations of the unique chemical environment over snow and ice in recent decades, particularly in the polar regions. have stimulated increasing interest in the boundary layer processes that mediate exchanges […]

7. Chemistry of the Antarctic boundary layer and the interface with snow: an overview of the CHABLIS campaign

   CHABLIS (Chemistry of the Antarctic Boundary Layer and the Interface with Snow) was a collaborative UK research project aimed at probing the detailed chemistry of the Antarctic boundary layer and […]

8. On the vertical distribution of boundary layer halogens over coastal Antarctica: implications for O3, HOx, NOx and the Hg lifetime

   A one-dimensional chemical transport model has been developed to investigate the vertical gradients of bromine and iodine compounds in the Antarctic coastal boundary layer (BL). The model has been applied […]

9. Behaviour of tracer diffusion in simple atmospheric boundary layer models

   1-D profiles and time series from an idealised atmospheric boundary layer model are presented, which show agreement with boundary layer measurements of polar NOx. Diffusion models are increasingly being used […]

10. Halogens and their role in polar boundary-layer ozone depletion

    During springtime in the polar regions, unique photochemistry converts inert halide salt ions (e.g. Br-) into reactive halogen species (e.g. Br atoms and BrO) that deplete ozone in the boundary […]

11. Imaging of firn isochrones across an Antarctic ice rise and implications for patterns of snow accumulation rate

    It has been an underlying assumption in many studies that near-surface layers imaged by ground-penetrating radar (GPR) can be interpreted as depositional markers or isochrones. It has been shown that […]

12. Wind-borne redistribution of snow across an Antarctic ice rise

    Redistribution of snow by the wind can drive spatial and temporal variations in snow accumulation that may affect the reconstruction of paleoclimate records from ice cores. In this paper we […]
