The Polar Front (PF) forms the southern boundary to the Polar Frontal Zone (PFZ) along the northern edge of the Antarctic Circumpolar Current (ACC). In a number of areas the […]
Rates of water loss were determined for four Coleoptera species: the herbivores Hydromedion sparsutum, Perimylops antarcticus (Family Perimylopidae) and the carnivores Trechisibus antarcticus, Oopterus soledadinus (Family Carabidae) collected during summer […]
The influence of feeding state on cold-adapted metabolism was investigated in the adults of two carabid beetles, Trechisibus antarcticus and Oopterus soledadinus (Coleoptera: Carabidae), which have been introduced to sub-Antarctic […]
We demonstrate that the observed enhancement in the fractional composition equation image of ring current O+ ions during magnetic storms can have a strong controlling effect on the excitation of […]
In a previous study it was reported that whistler- mode signals received at Faraday, Antarctica (65°S,64°W) and Dunedin, New Zealand (46°S, 171°E) with entry regions in Pacific longitudes (typically from […]
Understanding the causes of recent climatic trends and variability in the high-latitude Southern Hemisphere is hampered by a short instrumental record. Here, we analyse recent atmosphere, surface ocean and sea-ice […]
Measurements of the Earth’s magnetic field collected by low-Earth-orbit satellites such as Swarm and CHAMP, as well as at ground observatories, are dominated by sources in the Earth’s interior. However […]
Global biodiversity is in decline, with the marine environment experiencing significant and increasing anthropogenic pressures. In response marine protected areas (MPAs) have increasingly been adopted as the flagship approach to […]
The Southern Ocean is a key region for silica (Si) cycling, and the isotopic signatures established here influence the rest of the world’s oceans. The climate and ecosystem of the […]
The Arctic is currently undergoing drastic changes in climate, largely thought to be due to so-called ‘Arctic amplification’, whereby local feedbacks enhance global warming. Recently, a number of observational and […]
