Burial diagenesis and pore-fluid evolution in a Mesozoic back-arc basin: the Marambio Group, Vega Island, Antarctica
Read more of: Burial diagenesis and pore-fluid evolution in a Mesozoic back-arc basin: the Marambio Group, Vega Island, AntarcticaUpper Cretaceous shallow-marine sediments from Vega Island, Antarctica, contain five major authigenic phases; glauconite, pyrite, a zeolite mineral of the clinoptilolite-heulandite group, chlorite, and calcite. The framework sediment composition changes […]

Influence of temperature on growth rate and competition between two psychrotolerant Antarctic bacteria: low temperature diminishes affinity for substrate uptake
Read more of: Influence of temperature on growth rate and competition between two psychrotolerant Antarctic bacteria: low temperature diminishes affinity for substrate uptakeThe growth kinetics of two psychrotolerant Antarctic bacteria, Hydrogenophaga pseudoflava CR3/2/10 (2/10) and Brevibacterium sp. strain CR3/1/15 (1/15), were examined over a range of temperatures in both batch culture and […]

Modelling the selective effects of fishing on reproductive potential and population structure of squid
Read more of: Modelling the selective effects of fishing on reproductive potential and population structure of squidArtificial selection processes associated with harvesting may operate over relatively short time scales in short-lived semelparous species. The ommastrephid squid Illex argentinus on the Patagonian Shelf is the target of […]

Spatial variability of the major chemistry of the Antarctic ice sheet
Read more of: Spatial variability of the major chemistry of the Antarctic ice sheetA compilation of reliable data for sodium, nitrate, chloride and sulphate has been made. NO3 concentrations arc remarkably consistent across Antarctica, though there appears to be some correlation with altitude […]
