A review of geological constraints on the pre-break-up position of the Ellsworth Mountains within Gondwana: implications for Weddell Sea evolution
Read more of: A review of geological constraints on the pre-break-up position of the Ellsworth Mountains within Gondwana: implications for Weddell Sea evolutionIt 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 […]

Evidence for westward-flowing Weddell Sea Deep Water in the Falkland Trough, western South Atlantic
Read more of: Evidence for westward-flowing Weddell Sea Deep Water in the Falkland Trough, western South AtlanticThe 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 […]

Potential interactions between wandering albatrosses and longline fisheries for Patagonian toothfish at South Georgia
Read more of: Potential interactions between wandering albatrosses and longline fisheries for Patagonian toothfish at South GeorgiaWe 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. […]

Variations in the altitude of the F2 peak associated with trough-formation processes
Read more of: Variations in the altitude of the F2 peak associated with trough-formation processesA 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 […]

Antarctica and the evolution of taxonomic diversity gradients in the marine realm
Read more of: Antarctica and the evolution of taxonomic diversity gradients in the marine realmAlthough it will probably never be as complete as that known from any of the other continents, the Antarctic fossil record comprises a surprising amount of information. Originally gathered primarily […]
