Southern Hemisphere climate reconstructions are limited by quantity and spatial coverage of well resolved paleoclimaterecords from the last 2000 years. This was the motivation to drill an ice core at a new site in East Antarctica…
Lead (Pb) isotopic compositions and concentrations, and barium (Ba) and indium (In) concentrations have been determined at monthly resolution in five Law Dome (coastal Eastern Antarctica) ice core sections dated from ~1757 AD to ~1898 AD. [`]…
Environmental Earth Science … Pollution history
The efforts of Patterson and co-workers (Murozumi et al., 1969) to accurately measure Pb … concentrations in Greenland and Antarctic snow and ice produced the first reliable … determination of Pb pollution of the Earth’s polar ice sheets. Since then…
In recent times there has been increasing interest in Sr as an isotopic tracer in environmental … studies. There is the potential to characterise dust inputs at a certain site by transport of … material from source areas if the isotopic compositions of the site and source areas are … known.
Antarctic ice is an archive of evidence of climatic conditions and natural phenomena in the … Southern Hemisphere that extends approximately one million years into the past. We can … sense changes through the concentration of atmospheric gases, stable isotope ratios, terrestrial dust levels…
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…
