Age-related variation in reproductive traits in the wandering albatross: evidence for terminal improvement following senescence
Read more of: Age-related variation in reproductive traits in the wandering albatross: evidence for terminal improvement following senescenceThe 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 […]

Species distribution modelling in low-interaction environments: Insights from a terrestrial Antarctic system
Read more of: Species distribution modelling in low-interaction environments: Insights from a terrestrial Antarctic systemIt 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 […]

Microbial control of bromocarbon concentrations in coastal waters of the western Antarctic Peninsula
Read more of: Microbial control of bromocarbon concentrations in coastal waters of the western Antarctic PeninsulaThe 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 […]

Primary production export flux in Marguerite Bay (Antarctic Peninsula): Linking upper water-column production to sediment trap flux
Read more of: Primary production export flux in Marguerite Bay (Antarctic Peninsula): Linking upper water-column production to sediment trap fluxA 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, […]

Southern Hemisphere westerly wind changes during the Last Glacial Maximum: paleo-data synthesis
Read more of: Southern Hemisphere westerly wind changes during the Last Glacial Maximum: paleo-data synthesisChanges 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 […]

Cenozoic climate change and diversification on the continental shelf and slope: evolution of gastropod diversity in the family Solariellidae (Trochoidea)
Read more of: Cenozoic climate change and diversification on the continental shelf and slope: evolution of gastropod diversity in the family Solariellidae (Trochoidea)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 […]

Climate change and the polar regions
Read more of: Climate change and the polar regionsStretching 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 […]

Forecasting the Earth’s radiation belts and modelling solar energetic particle events: Recent results from SPACECAST
Read more of: Forecasting the Earth’s radiation belts and modelling solar energetic particle events: Recent results from SPACECASTHigh-energy charged particles in the van Allen radiation belts and in solar energetic particle events can damage satellites on orbit leading to malfunctions and loss of satellite service. Here we […]

Computing the volume response of the Antarctic Peninsula ice sheet to warming scenarios to 2200
Read more of: Computing the volume response of the Antarctic Peninsula ice sheet to warming scenarios to 2200The contribution to sea level to 2200 from the grounded, mainland Antarctic Peninsula ice sheet (APIS) was calculated using an ice sheet model initialized with a new technique computing ice […]

Space weather impacts on satellites and forecasting the Earth’s electron radiation belts with SPACECAST
Read more of: Space weather impacts on satellites and forecasting the Earth’s electron radiation belts with SPACECASTSatellites can be damaged by high energy charged particles in the Earth’s radiation belts and during solar energetic particle (SEP) events. Here we review the growing reliance on satellite services, […]
