Rutford Ice Stream, Antarctica
Rutford Ice Stream is in many ways a typical Antarctic outlet glacier. Constrained by a subglacial-bed trough to the east of the Ellsworth Mountains, it drains an area of 49,000 […]

High genetic diversity within Epimeria georgiana (Amphipoda) from the southern Scotia Arc
Read more of: High genetic diversity within Epimeria georgiana (Amphipoda) from the southern Scotia ArcDNA barcoding revealed four well-supported clades among amphipod specimens that keyed out to Epimeria georgiana Schellenberg, 1931, three clades with specimens from the southern Scotia Arc and one clade with […]

The tectonic history of the Ellsworth Mountains, West Antarctica: reconciling a Gondwana enigma
Read more of: The tectonic history of the Ellsworth Mountains, West Antarctica: reconciling a Gondwana enigmaEarly Paleozoic orogenesis has been recognized along the southern African (Saldanian orogeny) and East Antarctic (Ross orogeny) sectors of the Gondwana paleo- Pacific margin. However, the absence of a contemporaneous […]

Taxonomic diversity gradients through geological time
Read more of: Taxonomic diversity gradients through geological timeThere is evidence from the fossil record to suggest that latitudinal gradients in taxonomic diversity may be time-invariant features, although almost certainly not on the same scale as that seen […]

Rapid discrimination between four Antarctic fish species, genus Macrourus, using HRM analysis
Read more of: Rapid discrimination between four Antarctic fish species, genus Macrourus, using HRM analysisCorrect identification of species forms the basis of all biological studies from individual genetic variation to population genetics, stock assessments and understanding whole ecosystems. This often relies on skilled taxonomists […]

Investigations of an ‘ice plain’ in the mouth of Pine Island Glacier, Antarctica
Read more of: Investigations of an ‘ice plain’ in the mouth of Pine Island Glacier, AntarcticaWe present newly acquired airborne radar data showing ice thickness and surface elevation for Pine Island Glacier, Antarctica. These data, when combined with earlier measurements, suggest the presence of a […]
