A net sampling survey was conducted around the island of South Georgia in the austral summer 1981/1982 and again in winter 1983. This paper uses Principal Components Analysis to elucidate […]
Subduction of young, hot oceanic lithosphere and a major episode of lithospheric extension have been considered as key tectonomagmatic factors in the genesis of ‘Setouchi-type’ continental magnesian andesites. We present […]
New field mapping and an integrated trace element and Nd isotopic study have been undertaken on the Jurassic-Cretaceous Larsen Harbour Complex on the island of South Georgia, recognized as a […]
The Filchner‐Ronne Ice Shelf, the ocean cavity beneath it and the Weddell Sea that bounds it, form an important part of the global climate system by modulating ice discharge from […]
The second generation Antarctic magnetic anomaly compilation (ADMAP‐2) for the region south of 60oS includes some 3.5 million line‐km of aeromagnetic and marine magnetic data that more than doubles the […]
Results from ground-penetrating radar (GPR) measurements and shallow ice cores carried out during a scientific traverse between Dome Concordia (DC) and Vostok stations are presented in order to infer both […]
Little is known about the aerial transport of microbes, plants and animals into and between Antarctic terrestrial and freshwater habitats. Isolation by the circumpolar Southern Ocean restricts propagules to three […]
Heterogeneous chemistry producing active chlorine has been identified as crucial to Antarctic ozone depletion. Most attention has focussed on reactions on solid polar stratospheric cloud (PSC) particles, although there is […]
