1. Isotopic niches of sympatric Gentoo and Chinstrap Penguins: evidence of competition for Antarctic krill?

   As climate change, among other factors, is increasingly affecting Antarctic marine systems, competition for prey may increase between predators, particularly in the Antarctic Peninsula which has warmed more than elsewhere. […]

2. Key stages in the evolution of the Antarctic marine fauna

   We are beginning to appreciate that the origin of the modern Antarctic marine fauna is related to a series of key events throughout the Cenozoic era. In the first of […]

3. SAR imagery for detecting sea surface slicks: performance assessment of polarization-dependent parameters

   Remote sensing technology is an essential link in the global monitoring of the ocean surface, and radars are efficient sensors for detecting marine pollution. When used operationally by authorities, a […]

4. Genetic connectivity from the Arctic to the Antarctic: Sclerolinum contortum and Nicomache lokii (Annelida) are both widespread in reducing environments

   The paradigm of large geographic ranges in the deep sea has been challenged by genetic studies, which often reveal putatively widespread species to be several taxa with more restricted ranges. […]

5. Deglaciation and future stability of the Coats Land ice margin, Antarctica

   The East Antarctic Ice Sheet discharges into the Weddell Sea via the Coats Land ice margin. We have used geophysical data to determine the changing ice sheet configuration in this […]

7. Vertical thermospheric winds at the equatorward edge of the auroral oval

   A study has been made of vertical thermospheric winds in the vicinity of Halley, Antarctica (75.5°S, 26.8°W; L = 4.2). Strong downward winds, up to 50 m s−1, are frequently […]

8. Campanian-Maastrichtian (Cretaceous) stratigraphy of the James Ross Island area, Antarctica

   One of the most important outcrops of uppermost Cretaceous (Campanian–Maastrichtian) sedimentary rocks in the southern high latitudes occurs within the James Ross Island group, northeastern Antarctic Peninsula. These rocks comprise […]

9. Signature of burst particle precipitation on VLF signals propagating in the Antarctic Earth-ionosphere waveguide

   The burst precipitation of energetic electrons (≥40 keV), induced by interactions with lightning‐generated whistler mode waves, has been observed to cause phase and amplitude perturbations on subionospheric VLF signals (“Trimpi” […]

11. The annual variation in quiet time plasmaspheric electron density, determined from whistler mode group delays

    Whistler mode group delays from the VLF Doppler experiment at Faraday, Antarctica (65°S, 64°W) show an annual variation that has a maximum in December and a minimum in June/July. Assuming […]

12. Egg Size and Reproductive Output in the Deep-Water Prawn Pandalus borealis Kroyer, 1838

    The deep-water prawn Pandalus borealis Kroyer, 1838 was sampled at six locations from Krossfjord, Spitsbergen (79⚬N, close to the known northerly limit of distribution) to Kosterfjord, Sweden (58⚬N, close to […]
