1. Changes in Antarctic Peninsula tropospheric temperatures from 1956 to 1999: a synthesis of observations and reanalysis data

   The surface warming at Faraday station in the western Antarctic Peninsula is one of the largest observed anywhere over the last 50 years, yet the physical mechanisms driving this climate […]

2. Distinguishing East and West Antarctic sediment sources using the Pb isotope composition of detrital K-feldspar

   New Pb analyses of K feldspars (Kfs) from Archaean–Mesozoic crystalline rocks from across the Weddell Sea region of Antarctica show Pb isotopic compositions that vary geographically. Five distinct basement provinces […]

3. Trends in Antarctic geopotential height and temperature: A comparison between radiosonde and NCEP-NCAR reanalysis data

   A comparison of 40-yr (1960-99) trends in Antarctic geopotential height and temperature from quality controlled radiosonde observations and NCEP-NCAR reanalysis (NNR) data is undertaken. Observations from four Antarctic stations-having sufficiently […]

4. Analysis of recent circulation and thermal advection change in the northern Antarctic Peninsula

   Changes in circulation at 500 and 850 hPa and horizontal thermal advection between these two levels are examined at Bellingshausen station in the northern Antarctic Peninsula between 1969 and 2000. […]

5. Fortuynia (Acari: Oribatida: Ameronothroidea) from the marine littoral of southern Africa

   Three new taxa of the oribatid mite genus Fortuynia van der Hammen, 1960 (Ameronothroidea) were collected from the rocky shores and mangroves of southeastern Africa. These taxa, F. inhambanensis sp. […]

6. Springtime transitions in mesopause airglow and dynamics: photometer and MF radar observations in the Scandinavian and Canadian sectors

   Observations from 2 optical ground stations and 3 MF radars at high and mid-latitudes have been combined to describe “springtime transitions” in atomic oxygen and the mesopause wind fields and […]

7. Modeling tidal current profiles and vertical mixing beneath Filchner-Ronne Ice Shelf, Antarctica

   One of the warmest water masses beneath Filchner-Ronne Ice Shelf (FRIS) is dense, high salinity shelf water (HSSW) that flows into the sub-ice-shelf cavity from the ice front and occupies […]

8. Conflict or co-existence? Foraging distribution and competition for prey between Adelie and chinstrap penguins

   Adelie (Pygoscelis adeliae) and chinstrap penguins (P. antarctica) are morphologically and ecologically very similar, have very similar diet and breed sympatrically in the Scotia Arc from the South Sandwich Islands […]

10. 159 Ma Kjakebeinet lamproites (Dronning Maud Land, Antarctica) and their implications for Gondwana breakup processes

    Lamproite dykes that cross-cut Middle Jurassic Karoo-related flood basalts in Vestfjella, Dronning Maud Land, Antarctica, have been dated at 158.7 ± 1.6 Ma by 40Ar/39Ar incremental heating of phlogopite. Compared […]

11. Winds and tides in the mid-latitude Southern Hemisphere upper mesosphere recorded with the Falkland Islands SuperDARN radar

    Meteor wind data from the first year of operation of the Falkland Islands SuperDARN radar (52° S, 59° W) are used to characterize the atmospheric tides and background winds in […]

12. Comparison of analytical methods used for measuring major ions in the EPICA Dome C (Antarctica) ice core

    In the past, ionic analyses of deep ice cores tended to consist of a few widely spaced measurements that indicated general trends in concentration. The ion-chromatographic methods widely used provide […]
