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 […]

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 […]

What is cold adaptation and how should we measure it?
Read more of: What is cold adaptation and how should we measure it?Cold adaptation encompasses all those aspects of an organism’s physiology that allow it to live in polar regions. With the exception of the special case of the need to avoid […]
