Wave‐like structures in the upper atmospheric nightglow brightness were observed on the night of 22 August 2017, approximately 8 hr following a total solar eclipse. These wave‐like perturbations are signatures […]
Oceanic melting beneath ice shelves is the main driver of the current mass loss of the Antarctic ice sheet and is mostly parameterised in stand-alone ice-sheet modelling. Parameterisations are crude […]
A coordinated atmosphere-ocean research project, centered on a rare wintertime field campaign to the Iceland and Greenland Seas, seeks to determine the location and causes of dense water formation by […]
The recently discovered hydrothermal vent ecosystems in the Southern Ocean host a suite of vent-endemic species, including lepetodrilid limpets dominating in abundance. Limpets were collected from the chimneys, basalts and […]
Warming of the Antarctic Peninsula in the latter half of the 20th century was greater than any other terrestrial environment in the Southern Hemisphere, and obvious cryospheric and biological consequences […]
Biogeochemical cycling in high-latitude regions has a disproportionate impact on global nutrient budgets. Here, we introduce a holistic, multi-disciplinary framework for elucidating the influence of glacial meltwaters, shelf currents, and […]
During a survey of microfungi on the subantarctic island of South Georgia, large numbers of phylloplane yeasts were isolated in late spring from leaves of a tussock grass. The dominant […]
More than two hundred recoveries of giant petrels Macronectes halli and M. giganteus originally ringed at Bird Island, South Georgia, were analysed to determine the nature of any interspecific differences […]
Moult scores were collected from colour‐ringed individuals of known reproductive status of the two species of giant petrel, Macronectes halli and M. giganteus, at Bird Island, South Georgia between 1978–81. […]
The breeding biology and population dynamics of the two species of giant petrels, Macronectes halli and M. giganteus, were studied at Bird Island, South Georgia during 1978–81. The mean laying […]
During geomagnetic storms different partial pressure gradients in the auroral ionosphere may result in H+, He+, O+ and molecular ions drifting with different velocities along the Earth’s magnetic field line. […]
