The diet of grey-headed albatrosses at Diego Ramírez was analysed and compared to that of the … sympatric black-browed albatross. Diet composition was inferred from an analysis of prey hard parts present … in 103 chick regurgitates obtained during breeding seasons 2000, 2001 and 2002.
Lead, Ba and Bi concentrations and Pb isotopic compositions have been measured in Antarctic Law Dome (66.8‡S, 112.4‡E) ice dated from 1814 AD to 1819 AD by hermalionisation mass spectrometry to investigate the possible deposition of heavy metals from the 1815 AD eruption of Tambora volcano (8.5‡S…
The firn air "archive" enables reconstruction of atmospheric composition through the past century when many … significant changes occurred in the global atmosphere.
High precision multispecies trace gas measurements of Law Dome ice have been produced for the last 2000 years. The new records of CO2 and CH4 compare very well with the published Law Dome records of the last 1000 years. The new measurements are used to confirm the changes observed in these records…
