1. 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 […]

2. A new species of Diaphana from bathyal depths in the Weddell Sea, Antarctica and first record of Diaphana inflata (Strebel, 1908) in the high Antarctic (Gastropoda: Opisthobranchia)

   Diaphana haini n.sp. is described from Antarctica. With a depth range from about 400 to 2100 m, D. haini is the second Antarctic species of this genus to extend into […]

3. The shelled Magellanic Mollusca: with special reference to biogeographic relations in the Southern Ocean

   [Please note that the PDF file available is is a copy of the original PhD thesis, submitted to the University of Hamburg in 2000. It contains the same content as […]

4. Tectonic setting of primitive magmas in volcanic arcs: an example from the Antarctic Peninsula

   Primitive magmas representing mantle partial melts minimally affected by fractionation and assimilation are rare in the magmatic arc environment. Most examples are either associated with high rates of arc-parallel extension, […]

5. The abundance and biomass of choanoflagellates and other nanoflagellates in waters of contrasting temperature to the north-west of South Georgia in the Southern Ocean

   The abundance and biomass of different categories of autotrophic and heterotrophic nanoflagellates were determined in surface waters along a transect crossing the Polar Front to the north-west of South Georgia […]

6. The biology and evolution of Antarctic saline lakes in relation to salinity and trophy

   Five brackish to hypersaline lakes (Highway, Ace, Pendent, Williams and Rookery) in the Vestfold Hills, eastern Antarctica were investigated during the austral summer of 1999/2000. The aims were to characterise […]

7. Data report: Strontium isotope dating of barnacle fragments: Antarctic Peninsula Site 1103

   Strontium isotope ratios from multiple plates of two barnacle fragments from Site 1103 (Ocean Drilling Program Leg 178) provide maximum age estimates for the oldest glacial sedimentary package drilled. Three […]

8. Tectonic evolution of the Pacific margin of Antarctica. 1. Late Cretaceous tectonic reconstructions

   We present new Late Cretaceous tectonic reconstructions of the Pacific margin of Antarctica based on constraints from marine magnetic data and regional free-air gravity fields. Results from interpretation of new […]

9. The effect of Forbush decreases on tropospheric parameters over South Pole

   Egorova et al. (2000) conclude that Forbush decreases (FDs) in galactic cosmic rays have a significant effect on the atmosphere at Antarctic station Vostok (78.5°S, 106.9°E) via the mechanism of […]

10. Importance of plasma injection events for energization of relativistic electrons in the Jovian magnetosphere

    Effects of density decrease in plasma injection regions and a latitude-dependent wave normal angle distribution on the energization of electrons by whistler mode waves at Jupiter are investigated. Previous work […]

11. Diffuse auroral scattering by whistler mode chorus waves: Dependence on wave normal angle distribution

    Using the statistical CRRES measurements of the electric field intensities of lower band chorus (LBC) and upper band chorus (UBC) around L = 6 under geomagnetically moderate conditions, we evaluate […]

12. Case study of a mesospheric wall event over Ferraz station, Antarctica (62° S)

    On 16–17 July 2007 during an observational campaign at Comandante Ferraz Antarctic Station (62 degrees S, 58 degrees W), a mesospheric wall was observed with an airglow all-sky imager. The […]
