Radiocarbon dating
Radiocarbon dating uses the decay of a radioactive isotope of carbon (14C) to measure time
and date objects containing carbon-bearing material. With a half-life of 5,700±30 years …

Climate control on terrestrial biospheric carbon turnover
Terrestrial vegetation and soils hold three times more carbon than the atmosphere. Much
debate concerns how anthropogenic activity will perturb these surface reservoirs, potentially …

Microbial oxidation of lithospheric organic carbon in rapidly eroding tropical mountain soils
Lithospheric organic carbon (“petrogenic”; OCpetro) is oxidized during exhumation and
subsequent erosion of mountain ranges. This process is a considerable source of carbon …
