Spatial and temporal distributions of surface mass balance between Concordia and Vostok stations, Antarctica, from combined radar and ice core data: first results and detailed error analysis
Read more of: Spatial and temporal distributions of surface mass balance between Concordia and Vostok stations, Antarctica, from combined radar and ice core data: first results and detailed error analysisResults 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 […]

Reactions on sulphuric acid aerosol and on polar stratospheric clouds in the Antarctic stratosphere
Read more of: Reactions on sulphuric acid aerosol and on polar stratospheric clouds in the Antarctic stratosphereHeterogeneous 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 […]

Chick growth and survival in gentoo penguins (Pygoscelis papua): effect of hatching asynchrony and variation in food supply
Read more of: Chick growth and survival in gentoo penguins (Pygoscelis papua): effect of hatching asynchrony and variation in food supplyIn 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 […]

Annual variation in breeding biology of macaroni penguins,Eudyptes chvysolophus, at Bird Island, South Georgia
Read more of: Annual variation in breeding biology of macaroni penguins,Eudyptes chvysolophus, at Bird Island, South GeorgiaThe 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 […]

Ageing criteria in the Starling Sturnus vulgaris
Read more of: Ageing criteria in the Starling Sturnus vulgarisThe 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 […]
