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 […]

SAR imagery for detecting sea surface slicks: performance assessment of polarization-dependent parameters
Read more of: SAR imagery for detecting sea surface slicks: performance assessment of polarization-dependent parametersRemote 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 […]

Genetic connectivity from the Arctic to the Antarctic: Sclerolinum contortum and Nicomache lokii (Annelida) are both widespread in reducing environments
Read more of: Genetic connectivity from the Arctic to the Antarctic: Sclerolinum contortum and Nicomache lokii (Annelida) are both widespread in reducing environmentsThe 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. […]

Deglaciation and future stability of the Coats Land ice margin, Antarctica
Read more of: Deglaciation and future stability of the Coats Land ice margin, AntarcticaThe 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 […]

Vertical thermospheric winds at the equatorward edge of the auroral oval
Read more of: Vertical thermospheric winds at the equatorward edge of the auroral ovalA 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 […]

Campanian-Maastrichtian (Cretaceous) stratigraphy of the James Ross Island area, Antarctica
Read more of: Campanian-Maastrichtian (Cretaceous) stratigraphy of the James Ross Island area, AntarcticaOne 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 […]

Signature of burst particle precipitation on VLF signals propagating in the Antarctic Earth-ionosphere waveguide
Read more of: Signature of burst particle precipitation on VLF signals propagating in the Antarctic Earth-ionosphere waveguideThe 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” […]

The annual variation in quiet time plasmaspheric electron density, determined from whistler mode group delays
Read more of: The annual variation in quiet time plasmaspheric electron density, determined from whistler mode group delaysWhistler 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 […]

Egg Size and Reproductive Output in the Deep-Water Prawn Pandalus borealis Kroyer, 1838
Read more of: Egg Size and Reproductive Output in the Deep-Water Prawn Pandalus borealis Kroyer, 1838The 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 […]

The physiology of polar marine zooplankton
Read more of: The physiology of polar marine zooplanktonThe polar marine environment is characterised by low stable temperatures with seasonal variations ranging from ±3°C at lower latitudes to only ±0.2°C at high latitudes. The Arctic basin is dominated […]
