The atmospheric cycling of radiomethane and the“fossil fraction”of the methane source
radiomethane fossil fraction methane
2008/12/8
The cycling of 14CH4 ("radiomethane") through the atmosphere has been strongly perturbed in the industrial era by the release of 14C-free methane from geologic reservoirs ("fossil methane" emissions),...
Application of sediment core modelling to interpreting the glacial-interglacial record of Southern Ocean silica cycling
sediment core glacial-interglacial Southern Ocean silica cycling
2008/11/5
Sediments from the Southern Ocean reveal a meridional divide in biogeochemical cycling response to the glacial-interglacial cycles of the late Neogene. South of the present-day position of the Antarct...
