Populations of flesh-footed shearwaters on Lord Howe Island, Tasman Sea, have declined recently, with mortality in longline fisheries likely to be one of the major causes. It is therefore imperative […]
Euphausiids are an important component of the northern North Atlantic ecosystem and several species are found in the Irminger Sea. However, data on euphausiids in this region are few, particularly […]
The large and complex Getz Ice Shelf extends along nearly half of the West Antarctic coastline in the Amundsen Sea, and is exposed to a more variable ocean environment than […]
Recent 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 […]
Juvenile 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 […]
An 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 […]
An account is given of the unpublished work of Ivan Mackenzie Lamb, who spent almost 35 years working on the taxonomy and ecology of Antarctic lichens. Much of his meticulous […]
We carried out a superposed epoch analysis, using a database of substorm chorus events observed at Halley, Antarctica, within an hour of magnetic midnight, to define a set of 123 […]
Dynamic 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 […]
Phagocytosis 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 […]
The British Antarctic Survey (BAS) maintains a research and support station on Rothera Point (67 degrees 34’S, 68 degrees 08’W), located on the southeastern side of Adelaide Island, about 15 […]
