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 […]
In the gentoo penguin, Pygoscelis papua, we examined the effects of intra-clutch egg size differences and hatching asynchrony on differential chick growth and survival (including post-fledging survival), in five years […]
The breeding biology of the macaroni penguin, Eudyptes chrysolophus, was studied over four years, 1976 and 1986–88, at Bird Island, South Georgia. Birds were migratory, being absent during winter (May […]
The reliability of various criteria (throat feather length and the characteristics of rectrices and upper tail‐coverts) previously suggested for ageing Starlings was assessed using a sample of known‐aged birds. Total […]
