Magnetospheric electron temperatures inferred from whistler dispersion measurements
Read more of: Magnetospheric electron temperatures inferred from whistler dispersion measurementsElectron temperatures in the vicinity of the magnetospheric equator were estimated from dispersion measurements on 24 whistlers observed and digitally recorded at Halley, Antarctica (76 deg S, 27 deg W; […]

New significance for Antarctic biological collections and taxonomic research
Read more of: New significance for Antarctic biological collections and taxonomic researchCollections of preserved terrestrial and freshwater plants and animals, made since the earliest expeditions to the Antarctic and sub-Antarctic, have been the basis of our understanding of the biological composition […]

Imaging riometer and HF radar measurements of drifting F region electron density structures in the polar cap
Read more of: Imaging riometer and HF radar measurements of drifting F region electron density structures in the polar capA study of riometer, photometer, and ionosonde data from South Pole Station has revealed a class of unusual dayside absorption events which occur near local magnetic noon when South Pole […]

The equilibrium constant of NO2 with N2O4 and the temperature dependence of the visible spectrum of NO2: A critical review and the implications for measurements of NO2 in the polar stratosphere
Read more of: The equilibrium constant of NO2 with N2O4 and the temperature dependence of the visible spectrum of NO2: A critical review and the implications for measurements of NO2 in the polar stratosphereMeasurements of stratospheric NO2 by ground-based visible spectrometers rely on laboratory measurements of absorption cross-sections. We review low-temperature laboratory measurements, which disagree by amounts claimed to be significant. Our recalculation […]

Unravelling dates through the ages: geochronology of the Scottish metamorphic complexes
Read more of: Unravelling dates through the ages: geochronology of the Scottish metamorphic complexesThe paper by Giletti et al. 1961 is seen as a major landmark in the evolution of dating techniques in polymetamorphic terrains. We consider certain critical issues from each of […]

Cephalopod prey of the black-browed albatrossDiomedea melanophrys at South Georgia
Read more of: Cephalopod prey of the black-browed albatrossDiomedea melanophrys at South GeorgiaRegurgitations were collected from 41 black-browed albatross adults feeding chicks at Bird Island (54°S 38°W), South Georgia in February 1986. The samples were sorted into recognisable food categories and weighed. […]

More losers than winners in a century of future Southern Ocean seafloor warming
Read more of: More losers than winners in a century of future Southern Ocean seafloor warmingThe waters of the Southern Ocean are projected to warm over the coming century, with potential adverse consequences for native cold-adapted organisms. Warming waters have caused temperate marine species to […]
