1. Evidence for a large surface ablation zone in central East Antarctica during the last Ice Age

   Internal isochronous ice sheet layers, recorded by airborne ice-penetrating radar, were measured along an ice flowline across a large (> I km high) subglacial hill in the foreground of the […]

2. Photolysis frequency of NO2: measurement and modeling during the International Photolysis Frequency Measurement and Modeling Intercomparison (IPMMI)

   [1] The photolysis frequency of NO2, j(NO2), was determined by various instrumental techniques and calculated using a number of radiative transfer models for 4 days in June 1998 at the […]

3. Benthic diatom flora of freshwater and saline lakes in the Larsemann Hills and Rauer Islands (East Antarctica)

   A floristic and taxonomic survey was made of the diatom communities of sediments and microbial mats in 66 freshwater and saline lakes and pools in the Larsemann Hills, Rauer Islands […]

5. Limited dechlorination of sea-salt aerosols during the last glacial period: evidence from the European Project for Ice Coring in Antarctica (EPICA) Dome C ice core

   Chloride (Cl-) and sodium (Na+) in ice cores originate mainly from sea salt, and one would thus expect the Cl-/Na+ ratio to reflect the seawater ratio. However, at Dome C, […]

6. Stratospheric temperatures in Antarctic winter: does the 40-year record confirm mid-latitude trends in stratospheric water vapour?

   Water vapour is a potent greenhouse gas, and the observed increases in water vapour in the stratosphere act to cool it. Possible changes in stratospheric temperatures are important for future […]

7. Solar UV irradiation conditions on the surface of Mars

   The UV radiation environment on planetary surfaces and within atmospheres is of importance in a wide range of scientific disciplines. Solar UV radiation is a driving force of chemical and […]

8. Significance of lightning-generated whistlers to inner radiation belt electron lifetimes

   The behavior of high-energy electrons trapped in the Earth’s Van Allen radiation belts has been extensively studied, through both experimental and theoretical techniques. While the evidence for whistler induced electron […]

9. Anti-parallel reconnection at the dayside magnetopause: ionospheric signatures and implications for the low latitude boundary layer

   Reconnection at the dayside magnetopause is of fundamental importance in determining the dynamics and composition of the magnetosphere and the high latitude ionosphere. There are two competing hypotheses for such […]

10. Ultramafic lamprophyres of the Ferrar large igneous province: evidence for a HIMU mantle component

    Ultramafic lamprophyre (UML) dykes from the Ferrar Province (Pensacola Mountains) of Antarctica preserve trace element and isotope signatures similar to Bouvet volcanic rocks, which are considered to reflect the palaeo […]

11. Basal topography and ice flow in the Bailey/Slessor region of East Antarctica

    An airborne radio-echo sounding campaign carried out in the upper reaches of Bailey Ice Stream and Slessor Glacier, in Coats Land, East Antarctica, has revealed that tributaries of enhanced flow […]

12. Thinning of the Antarctic Peninsula lithosphere through the Mesozoic: evidence from Middle Jurassic basaltic lavas

    Rare basaltic volcanic rocks from the northern Antarctic Peninsula (Jason Peninsula) are established as marginally predating a silicic large igneous province, which developed along the proto-Pacific margin of Gondwana. Ar-40-Ar-39 […]
