In situ measurements of Antarctic snow compaction compared with predictions of models
Read more of: In situ measurements of Antarctic snow compaction compared with predictions of modelsWe describe in situ measurements of the compaction of Antarctic snow. At three different sites in Antarctica, the rate of compaction was measured hourly, over various depth intervals, for up […]

Antarctic krill 454 pyrosequencing reveals chaperone and stress transcriptome
Read more of: Antarctic krill 454 pyrosequencing reveals chaperone and stress transcriptomeBackground: The Antarctic krill Euphausia superba is a keystone species in the Antarctic food chain. Not only is it a significant grazer of phytoplankton, but it is also a major […]

Dynamics of seasonal movements by a trans-Pacific migrant, the Westland petrel
Read more of: Dynamics of seasonal movements by a trans-Pacific migrant, the Westland petrelKnowledge of the dynamics of long-distance migrations of pelagic seabirds is limited. Recent advances in tracking technology have yielded detailed, continuous accounts of the movements of individual seabirds over large […]

Albatrosses following fishing vessels: how badly hooked are they on an easy meal?
Read more of: Albatrosses following fishing vessels: how badly hooked are they on an easy meal?Fisheries have major impacts on seabirds, both by changing food availability and by causing direct mortality of birds during trawling and longline setting. However, little is known about the nature […]

Estimating ice thickness in South Georgia from SRTM elevation data
Read more of: Estimating ice thickness in South Georgia from SRTM elevation dataSouth Georgia is a glaciated island in the South Atlantic, which provides a primary nesting site for the albatrosses and petrels of the Southern Ocean. 60% of the island is […]

End-to-end models for the analysis of marine ecosystems: challenges, issues and next steps
Read more of: End-to-end models for the analysis of marine ecosystems: challenges, issues and next stepsThere is growing interest in models of marine ecosystems that deal with the effects of climate change through the higher trophic levels. Such end-to-end models combine physicochemical oceanographic descriptors and […]

Phylum Tardigrada: A re-evaluation of the Parachela
Read more of: Phylum Tardigrada: A re-evaluation of the ParachelaWe assessed the available morphological evidence to see if this corroborates the paraphyly in the Parachela (Tardigrada) as suggested by recent molecular data. We reconcile molecular phylogenetics with alpha morphology, […]

Lithologic mapping in the Oscar II Coast area, Graham Land, Antarctic Peninsula using ASTER data
Read more of: Lithologic mapping in the Oscar II Coast area, Graham Land, Antarctic Peninsula using ASTER dataThe results of the first attempt to use Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data for the purposes of lithologic mapping on the Antarctic Peninsula are presented for […]

A consistent data set of Antarctic ice sheet topography, cavity geometry, and global bathymetry
Read more of: A consistent data set of Antarctic ice sheet topography, cavity geometry, and global bathymetrySub-ice shelf circulation and freezing/melting rates in ocean general circulation models depend critically on an accurate and consistent representation of cavity geometry. Existing global or pan-Antarctic data sets have turned […]

An improved bathymetry compilation for the Bellingshausen Sea, Antarctica, to inform ice-sheet and ocean models
Read more of: An improved bathymetry compilation for the Bellingshausen Sea, Antarctica, to inform ice-sheet and ocean modelsThe southern Bellingshausen Sea (SBS) is a rapidly-changing part of West Antarctica, where oceanic and atmospheric warming has led to the recent basal melting and break-up of the Wilkins ice […]

Ice-stream response to ocean tides and the form of the basal sliding law
Read more of: Ice-stream response to ocean tides and the form of the basal sliding lawThe response of ice streams to ocean tides is investigated. Numerical modelling experiments are conducted using a two-dimensional flow-line model of coupled ice-stream and ice-shelf flow. The model includes all […]
