The dynamics of idealized katabatic flow over a moderate slope and ice shelf
Read more of: The dynamics of idealized katabatic flow over a moderate slope and ice shelfA non-hydrostatic numerical weather prediction model has been employed to Simulate idealized katabatic flows over a moderate slope and adjoining ice shelf. The topography of Coats Land and the adjoining […]

Biomass and energy transfer to baleen whales in the South Atlantic sector of the Southern Ocean
Read more of: Biomass and energy transfer to baleen whales in the South Atlantic sector of the Southern OceanBaleen whales are an important group of predators on Antarctic krill in the Southern Ocean. During the CCAMLR 2000 Survey to estimate the biomass and distribution of Antarctic krill, International […]

Spatial distribution of predator/prey interactions in the Scotia Sea: implications for measuring predator/fisheries overlap
Read more of: Spatial distribution of predator/prey interactions in the Scotia Sea: implications for measuring predator/fisheries overlapThe measurement of spatial overlap between predators and fisheries exploiting a common prey source is dependent upon the measurement scale used; inappropriate scales may produce misleading results. Previous assessments of […]

Widening the net: spatio-temporal variability in the krill population structure across the Scotia Sea
Read more of: Widening the net: spatio-temporal variability in the krill population structure across the Scotia SeaResolving the spatial variability in the population structure of Antarctic krill (Euphausia superba) requires a synoptic sample, as in the design of the CCAMLR 2000 Survey. However, this approach is […]

Lower Jurassic floras from Hope Bay and Botany Bay, Antarctica
Read more of: Lower Jurassic floras from Hope Bay and Botany Bay, AntarcticaHope Bay and Botany Bay, Graham Land, Antarctica have yielded two of the most diverse floras known from the Jurassic. Because of its high diversity, as well as its early […]

Vertical migration strategies with respect to advection and stratification in a semi-enclosed lough: a comparison of mero- and holozooplankton
Read more of: Vertical migration strategies with respect to advection and stratification in a semi-enclosed lough: a comparison of mero- and holozooplanktonPatterns of zooplankton vertical movement are often difficult to interpret because of multiple, complex and confounding environmental factors. Behavioural adaptations to these environmental variables are compared within and between the […]

A reinterpretation of sea-salt records in Greenland and Antarctic ice cores?
Read more of: A reinterpretation of sea-salt records in Greenland and Antarctic ice cores?It has recently been shown that much sea-salt aerosol around the coast of Antarctica is generated not from open water, but from the surface of newly formed sea ice. Previous […]

Cambrian palaeomagnetic data confirm a Natal Embayment location for the Ellsworth-Whitmore Mountains, Antarctica, in Gondwana reconstructions
Read more of: Cambrian palaeomagnetic data confirm a Natal Embayment location for the Ellsworth-Whitmore Mountains, Antarctica, in Gondwana reconstructionsThe Ellsworth-Whitmore Mountains (EWM) are one of five terranes that form West Antarctica. Constraining the positions of these terranes in pre-break up Gondwana is crucial to understanding the history of […]

Antarctic shallow-water mega-epibenthos: shaped by circumpolar dispersion or local conditions?
Read more of: Antarctic shallow-water mega-epibenthos: shaped by circumpolar dispersion or local conditions?The mega-epibenthos of two different geographic areas, the Antarctic Peninsula and the high Antarctic (eastern Weddell Sea), were investigated using underwater video. The distribution of the marine fauna at shallow […]

Direct determination of mercury at the sub-picogram per gram level in polar snow and ice by ICP-SFMS
Read more of: Direct determination of mercury at the sub-picogram per gram level in polar snow and ice by ICP-SFMSAn analytical method for the direct determination of mercury (Hg) in polar snow and ice cores and surface snow based on inductively coupled plasma sector field mass spectrometry (ICP-SFMS) has […]
