1. Identifying areas of low-profile ice sheet and outcrop damming in the Antarctic ice sheet by ERS-1 satellite altimetry

   A digital elevation model (DEM) of the surface of the Antarctic ice sheet is compared with a simple two-dimensional ice-flow model to illuminate gross distortions (>500 m) of the ice-surface […]

3. A Lower Cretaceous, syn-extensional magmatic source for a linear belt of positive magnetic anomalies: the Pacific Margin Anomaly (PMA), western Palmer Land, Antarctica

   Ar–Ar laserprobe dating suggests that in western Palmer Land, plutons associated with a curvilinear belt of positive magnetic anomalies along the Pacific margin of the Antarctic Peninsula, the Pacific Margin […]

4. The metazoan meiofauna in its biogeochemical environment: the case of an Antarctic coastal sediment

   The metazoan meiobenthos was investigated in an Antarctic coastal sediment (Factory Cove, Signy Island, Antarctica). The fine sands contained much higher abundances compared to major sublittoral sediments worldwide. Classified second […]

5. Validation of ground-based visible measurements of total ozone by comparison with Dobson and Brewer spectrophotometers

   Comparisons of total column ozone measurements from Dobson, Brewer and SAOZ instruments are presented for the period 1990 to 1995 at seven stations covering the mid- and the high northern […]

6. Analysis of synoptic-scale low pressure systems within the Antarctic Peninsula sector of the circumpolar trough

   Satellite imagery of the Antarctic Peninsula, Bellingshausen Sea, and Weddell Sea region, together with operational meteorological analyses, are used to investigate the development, tracks, and structure of synoptic-scale weather systems […]

7. Understanding Antarctic Peninsula precipitation distribution and variability using a numerical weather prediction model

   Daily precipitation fields and annual means from the European Centre for Medium-range Weather Forecasts re-analysis exercise are used to examine the distribution and variability of precipitation across the Antarctic Peninsula. […]

8. Use of at-sea distribution data to derive potential foraging ranges of macaroni penguins during the breeding season

   Macaroni penguins are the main avian consumer of Antarctic krill in the vicinity of South Georgia. The largest breeding colonies occur on small offshore islands to the northwest of the […]

9. Analysis of haul data from the South Georgia krill fishery

   Data from individual hauls carried out by vessels operating in the South Georgia krill fishery between 1994 and 1996 were examined and a range of descriptive measurements reflecting the fishery […]

10. Is a periglacial biota responsible for enhanced dielectric response in basal ice from the Greenland Ice Core Project ice core?

    A detailed dielectric profiling (DEP) conductivity profile (σ∞) measured in the 6 m of the basal silty ice sequence from the Greenland Ice Core Project (GRIP) ice core (Summit, Central […]

11. Temperature dependence and acclimatory response of amylase in the High Arctic springtail Onychiurus arcticus (Tullberg) compared with the temperate species Protaphorura armata (Tullberg)

    Amylolytic activity was measured in whole body homogenates of High Arctic (Onychiurus arcticus) and temperate (Protaphorura armata) springtails (Collembola: Onychiuridae) in the temperature range 5–55°C. A pH of ca. 8 […]

12. Distribution and biogeography of oribatid mites (Acari: Oribatida) in Antarctica, the sub-Antarctic islands and nearby land areas

    Oribatid mites are an ancient group of cosmopolitan terrestrial arthropods with limited trans-oceanic dispersal abilities. They provide an opportunity to answer questions concerning the role played by Gondwanaland, either as […]
