1. Mixed layer lateral eddy fluxes mediated by air-sea interaction

   The modulation of air-sea heat fluxes by geostrophic eddies due to the stirring of temperature at the sea surface is discussed and quantified. It is argued that the damping of […]

2. Analysis of a regional change in the sign of the SAM-temperature relationship in Antarctica

   This study examines regional atmospheric circulation changes associated with a reversal in the sign of the relationship between the Southern Annular Mode (SAM) and near-surface temperatures at Halley station, East […]

3. Vascular plant success in a warming Antarctic may be due to efficient nitrogen acquisition

   For the past 50 years there has been rapid warming in the maritime Antarctic1, 2, 3, with concurrent, and probably temperature-mediated, proliferation of the two native plants, Antarctic pearlwort (Colobanthus […]

4. How committed are we to monitoring human impacts in Antarctica?

   Under the Antarctic Treaty System, environmental monitoring is a legal obligation for signatory nations and an essential tool for managers attempting to minimize local human impacts, but is it given […]

5. Dynamics of the Antarctic and Arctic mesosphere and lower thermosphere – Part 1: Mean winds

   Zonal and meridional winds have been measured in the upper mesosphere and lower thermosphere at polar latitudes using two ground-based meteor radars. One radar is located at Rothera (68° S, […]

6. Seasonal physiology and ecology of Antarctic marine benthos predators and scavengers

   Pronounced seasonality in photoperiod and phytoplankton availability drives key physiological processes in many Antarctic primary consumers. To test the hypothesis that carnivores would be less markedly affected by environmental seasonality […]

7. Phylogenetics of Baleen Whales

   At present, there are 15 species of baleen whales that belong to the monophyletic suborder Mysticeti. The family-level designations of Balaenidae (right and bowhead whales) and Neobalaenidae (pygmy right whales) […]

8. Intercomparison of slant column measurements of NO2 and O4 by MAX-DOAS and zenith-sky UV and visible spectrometers

   In June 2009, 22 spectrometers from 14 institutes measured tropospheric and stratospheric NO2 from the ground for more than 11 days during the Cabauw Intercomparison Campaign of Nitrogen Dioxide measuring […]

9. Experimental growth pattern calibration of Antarctic scallop shells (Adamussium colbecki, Smith 1902) to provide a biogenic archive of high-resolution records of environmental and climatic changes

   To determine the potential of Antarctic bivalve shells as biomonitors for environmental and climatic variations in polar marine areas, we developed a growth model for juvenile Adamussium colbecki Smith, 1902 […]

10. Methane and monsoons

    The rising trend in atmospheric concentrations of methane over the past 5,000 years has been attributed to human agency. A modelling study, of a power that has only now become […]

11. Magmatic evolution of a dying spreading axis: evidence for the interaction of tectonics and mantle heterogeneity from the fossil Phoenix Ridge, Drake Passage

    New 40Ar–39Ar ages of 5.6 to 1.3 Ma for lavas from the fossil Phoenix Ridge in the Drake Passage show that magmatism continued for at least 2 Ma after the […]

12. Changes in lichen diversity and community structure with fur seal population increase on Signy Island, South Orkney Islands

    Signy Island has experienced a dramatic increase in fur seal numbers over recent decades, which has led to the devastation of lowland terrestrial vegetation, with the eradication of moss turfs […]
