Fractal dimensions (D) of image perimeters of 4 macroalgae (Macrocystis pyrifera, Desmarestia menziesii, Schizoseris condensata, Palmaria georgica) collected at South Georgia, Southern Ocean were established over a wide scale range. […]
South Georgia, an extremely isolated island within the Antarctic Convergence, was covered by an extensive icecap until ~10,000 years ago. In consequence the depauperate intertidal fauna is of recent origin […]
It has long since been recognised that the Ellsworth-Whitmore mountains (EWM) crustal block possesses an anomalous structural and stratigraphic history relative to its neighbouring West Antarctic crustal blocks, and the […]
The North Scotia Ridge controls the eastward and northward flow of the Antarctic Circumpolar Current (ACC) emerging from Drake Passage. Existing physical oceanographic data in this region are sparse and […]
We examine the extent of overlap between South Georgia wandering albatrosses (Diomedea exulans) and local longline fishing for Patagonian toothfish (Dissostichus eleginoides), using satellite-tracking data and precise haul locations, respectively. […]
We review quantitative studies of the cephalopod diet of seabirds, with details of all species forming more than 5% by numbers or mass of seabird diets. Although squid are widespread […]
A novel approach is described which can help to determine, from ground-based data, which of the possible production mechanisms for the mid-latitude F-region ionospheric trough is dominant during a particular […]
New correlations of marine clastic sedimentary rocks exposed within the James Ross Basin, Antarctica have shown that the mid-to late Cretaceous succession is in excess of 5 km thick. Plotting […]
Praeaucellina umbonoradiata gen. et sp. nov. is a small pteriomorph bivalve from the Upper Jurassic-Lower Cretaceous of Antarctica which can be referred to the family Oxytomidae, within the superfamily Monotoidea. […]
