Lead Isotopes and Selected Metals in Ice from Law Dome, Antarctica
The isotopic composition of Pb and the concentrations of.Pb, Ba and Bi were measured in selected ice-core samples from Law Dome, East AntarctIca, to a depth of 1196 m. The range of concentrations found in decontaminated ice was 0.03\.5 pg g I for Pb, 0.96.1pggl for Ba and 0.417 fgg I for Bi , excluding the deepest sample which contained rv I p:}6m of rock dust. The abundances of all four stable...
متن کاملAnthropogenic lead isotopes in Antarctica
We report the first measurements of Pb isotopes in Antarctic snow, which show that even recent snow containing 2.3 pg/g is highly polluted with anthropogenic Pb. This follows from a comparison of isotope abundances of Pb in surface snow and terrestrial dust extracted from ancient Antarctic ice (Dome C, depth 308 m, approximate age 7,500 a BP), the latter being distinctly more radiogenic. This r...

متن کامل1-D-ice flow modelling at EPICA Dome C and Dome Fuji, East Antarctica
One-dimensional (1-D) ice flow models are used to construct the age scales at the Dome C and Dome Fuji drilling sites (East Antarctica). The poorly constrained glaciological parameters at each site are recovered by fitting independent age markers identified within each core. We reconstruct past accumulation rates, that are larger than those modelled using the classical vapour saturation pressur...
