In the Southern Ocean, that is areas south of the Polar Front, long-term oceanographic cooling, geographic separation, development of isolating current and wind systems, tectonic drift and fluctuation of ice […]
The geographical coverage of a comprehensive dataset on Antarctic macrobenthic communities is provided for the first time. Since the sampling methods applied since the 1950s vary considerably, a robust analysis […]
Ice streams provide major drainage pathways for the Antarctic ice sheet. The stress distribution and style of flow in such ice streams produce elastic and rheological anisotropy, which informs ice-flow […]
The processes driving age-related variation in demographic rates are central to understanding population and evolutionary ecology. An increasing number of studies in wild vertebrates find evidence for improvements in reproductive […]
It is widely acknowledged that in the terrestrial Antarctic, interspecific interactions are typically unimportant in determining species distributions and community structure. Therefore, correlative models should prove useful for predicting current […]
The marine environment is known to be a source of CHBr3 and CH2Br2 and hence ozone-depleting inorganic bromine to the troposphere but, to date, the dominant processes controlling their concentrations […]
A study was carried out to assess primary production and associated export flux in the coastal waters of the western Antarctic Peninsula at an oceanographic time-series site. New, i.e., exportable, […]
Changes in the strength and position of Southern Hemisphere westerly winds during the Last Glacial cycle have been invoked to explain both millennial and glacial–interglacial climate fluctuations. However, neither paleo […]
Recent expeditions have revealed high levels of biodiversity in the tropical deep-sea, yet little is known about the age or origin of this biodiversity, and large-scale molecular studies are still […]
Stretching back to Scott’s doomed Terra Nova expedition, the enigmatic polar regions have long been a source of fascination for explorers and scientists alike. Today the polar regions remain a […]
