A detailed morphologic and seismic stratigraphic analysis of the continental margin offshore of Adelaide Island on the Pacific Margin of the Antarctic Peninsula (PMAP) is described based on the study […]
Polar ice cores provide exceptional archives of past environmental conditions. The dating of ice cores and the estimation of the age-scale uncertainty are essential to interpret the climate and environmental […]
The Last Interglacial (LIG, ~129-116 thousand years Before Present, hereafter ka) represents an ideal case study to understand the climate mechanisms at play under a warmer-than-present climate. However a spatio-temporal […]
In seabirds, the extent of population genetic and phylogeographic structure varies extensively among species. Genetic structure is lacking in some species, but present in others despite the absence of obvious […]
Antarctic terrestrial biodiversity occurs almost exclusively in ice-free areas that cover less than 1% of the continent. Climate change will alter the extent and configuration of ice-free areas, yet the […]
Competition between two psychrotolerant bacteria was examined in glycerol-limited chemostat experiments subjected to non-steady-state conditions of temperature. One bacterium, a Brevibacterium sp. strain designated CR3/1/15, responded rapidly to temperature change, […]
Visible spectra of the zenith-sky were recorded at Faraday in Antartica (65°S) during 1990. Line-of-sight ozone amounts were deduced by fitting laboratory cross-sections to the spectra. At the lattitude of […]
Ideas from dynamical systems theory have been used in an observational field campaign in the Southern Ocean to provide information on the mixing structure of the flow. Instantaneous snapshops of […]
