1. 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. […]

2. 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 […]

3. 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 […]

4. 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 […]

6. 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 […]

7. 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 […]

8. 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 […]

9. 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 […]

10. 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 […]

11. 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, […]

12. 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 […]
