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 …

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

Lithospheric organic carbon (“petrogenic”; OCpetro) is oxidized during exhumation and
subsequent erosion of mountain ranges. This process is a considerable source of carbon …

Archaeological plant remains are a valuable source of information about the social and
environmental conditions experienced by past societies. Full exploitation of the informative …

Burial of terrestrial organic carbon (OC terr) in marginal sea sediments is a key component
of the carbon cycle, exerting long-term influence on atmospheric CO 2 and climate …

Sediments in deep ocean trenches may contain crucial information on past earthquake
history and constitute important sites of carbon burial. Here we present 14C data on bulk …

The erosion and weathering of mountain ranges exert a key control on the long-term (105–
106 yr) cycling of carbon between Earth's surface and crust. The net carbon budget of a …

Abstract The Atacama Desert in Chile is known to be one of the driest deserts on Earth, with
dominating hyperaridity at least since the Miocene. During recent times, however, especially …

The sedimentation of organic carbon in the Ulleung Basin, in the southwestern East Sea
(Japan Sea) was investigated using radiocarbon and sterols. The accumulation rates of …

Black carbon is ubiquitous in the marine environment. However, whether it accumulates in
the deepest ocean region, the hadal zone, is unknown. Here we measure the concentration …
