[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 […]
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, […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
Predicting how climate will change in the future requires a sound understanding of physical processes. This is underpinned by observation of how and why climate has changed in the past. […]
Iodine compounds were measured above, below and within the sea ice of the Weddell Sea during a cruise in 2009, to make progress in elucidating the mechanism of local enhancement […]
