The influence of winds, sea-surface temperature and precipitation anomalies on Antarctic regional sea-ice conditions during IPY 2007
Read more of: The influence of winds, sea-surface temperature and precipitation anomalies on Antarctic regional sea-ice conditions during IPY 2007The 2007 International Polar Year (IPY) in the Antarctic was distinguished by strong regional and seasonal ice-atmosphere-ocean anomalies associated with an overall weakening of the prevailing westerly circulation. Here we […]

Time-dependence of the spatial pattern of accumulation rate in East Antarctica deduced from isochronic radar layers using a 3D numerical ice-flow model
Read more of: Time-dependence of the spatial pattern of accumulation rate in East Antarctica deduced from isochronic radar layers using a 3D numerical ice-flow modelIn East Antarctica surface mass balance data can only be obtained from the sparsely distributed ice cores when considering time periods greater than a few decades. Observations of internal layers […]

Automated processing to derive dip angles of englacial radar reflectors in ice sheets
Read more of: Automated processing to derive dip angles of englacial radar reflectors in ice sheetsWe present a novel automated processing method for obtaining layer dip from radio-echo sounding (RES) data. The method is robust, easily applicable and can be used to process large (several […]

High-resolution modelling of the shelf and open ocean adjacent to South Georgia, Southern Ocean
Read more of: High-resolution modelling of the shelf and open ocean adjacent to South Georgia, Southern OceanThe marine ecosystem on the shelf and open ocean adjacent to South Georgia is extraordinarily rich, with a history of commercial exploitation. Although much progress has been made, attempts at […]

Bayesian estimation of basal conditions on Rutford Ice Stream, West Antarctica, from surface data
Read more of: Bayesian estimation of basal conditions on Rutford Ice Stream, West Antarctica, from surface dataThe determination of basal properties on ice streams from surface data is formulated as a Bayesian statistical inference problem. The theory is applied to a flowline on Rutford Ice Stream, […]

The vertical connection of the quasi-biennial oscillation- modulated 11 year solar cycle signature in geopotential height and planetary waves during Northern Hemisphere early winter
Read more of: The vertical connection of the quasi-biennial oscillation- modulated 11 year solar cycle signature in geopotential height and planetary waves during Northern Hemisphere early winterWe analyzed observational geopotential height data to provide some new insights on the 11 year solar cycle signal in the Northern Hemisphere early winter and its modulation by the quasi-biennial […]

South Georgia: a key location for linking physiological capacity to distributional changes in response to climate change
Read more of: South Georgia: a key location for linking physiological capacity to distributional changes in response to climate changeAntarctic marine invertebrates from the Western Antarctic Peninsula (WAP) are generally stenothermal, with three-month survival and activity limits above the average maximum summer seawater temperature (1.0 degrees C) of 1-6 […]

Temporal and spatial metabolic rate variation in the Antarctic springtail Gomphiocephalus hodgsoni
Read more of: Temporal and spatial metabolic rate variation in the Antarctic springtail Gomphiocephalus hodgsoniSpatial and temporal environmental variation in terrestrial Antarctic ecosystems are known to impact species strongly at a local scale, but the ways in which organisms respond (e.g. physiologically, behaviourally) to […]

Dormancy and resistance in harsh environments
Read more of: Dormancy and resistance in harsh environmentsMany organisms have evolved the ability to enter into and revive from a dormant state. They can survive for long periods in this state (often even months to years), yet […]

Gilthead sea bream (Sparus auratus) and European sea bass (Dicentrarchus labrax) expressed sequence tags: Characterization, tissue-specific expression and gene markers
Read more of: Gilthead sea bream (Sparus auratus) and European sea bass (Dicentrarchus labrax) expressed sequence tags: Characterization, tissue-specific expression and gene markersThe gilthead sea bream. Sparus auratus, and the European sea bass, Dicentrarchus labrax, are two of the most important marine species cultivated in Southern Europe. This study aimed at increasing […]
