Decadal freshening of the Antarctic Bottom Water exported from the Weddell Sea
Read more of: Decadal freshening of the Antarctic Bottom Water exported from the Weddell SeaRecent decadal changes in Southern Hemisphere climate have driven strong responses from the cryosphere. Concurrently, there has been a marked freshening of the shelf and bottom waters across a wide […]

Juveniles are more resistant to warming than adults in 4 species of Antarctic marine invertebrates
Read more of: Juveniles are more resistant to warming than adults in 4 species of Antarctic marine invertebratesJuvenile stages are often thought to be less resistant to thermal challenges than adults, yet few studies make direct comparisons using the same methods between different life history stages. We […]

On the formulation of snow thermal conductivity in large-scale sea ice models
Read more of: On the formulation of snow thermal conductivity in large-scale sea ice modelsAn assessment of the performance of a state-of-the-art large-scale coupled sea ice – ocean model, including a new snow multilayer thermodynamic scheme, is performed. Four 29-years-long simulations are compared against […]

Erosional history of the Transantarctic Mountains deduced from sand grain detrital modes in CRP-2/2A, Victoria Land Basin, Antarctica
Read more of: Erosional history of the Transantarctic Mountains deduced from sand grain detrital modes in CRP-2/2A, Victoria Land Basin, AntarcticaDynamic provenance variations are deduced from sand-grain detrital modes in samples obtained from the CRP-2/2A drillcore. Below an important unconformity at 307 metres below sea floor (mbsf), sand grains in […]

Induced in vitro phagocytosis of the Antarctic starfish Odontaster validus (Koehler 1906) at 0°C
Read more of: Induced in vitro phagocytosis of the Antarctic starfish Odontaster validus (Koehler 1906) at 0°CPhagocytosis was studied in vitro using coelomic fluid of the Antarctic starfish Odontaster validus at 0°C. The number of coelomocytes present was determined and the phagocytic activity of the phagocytic […]
