The response of the terrestrial biosphere to warming remains one of the most poorly
understood and quantified aspects of the climate system. One way to test the behavior of the …

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

Conspectus This Account presents a new discipline, single sample molecular chronology
(SSMC), which studies the relative age of an individual compound occurring in several …

Permafrost thaw in Arctic watersheds threatens to mobilize hitherto sequestered carbon. We
examine the radiocarbon activity (F14C) of dissolved organic carbon (DOC) in the northern …

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 …

Hydrodynamic sorting has been shown to strongly influence the composition and age of
organic carbon (OC) during sediment transport and burial in the marine environment, yet …

Constraining the origins, transport history, and burial efficiency of terrestrial organic carbon
(OC terr) accumulating in marine sediments is of fundamental importance for understanding …

Sedimentary high molecular weight (HMW) n-alkyl lipids derived from the waxes of terrestrial
plants are common target compounds in biogeochemical and paleoenvironmental research …

Natural and human-induced hydrological changes can influence organic carbon (OC)
composition in fluvial systems, with biogeochemical consequences in both terrestrial and …

Perylene is a frequently abundant, and sometimes the only polycyclic aromatic hydrocarbon
(PAH) in aquatic sediments, but its origin has been subject of a longstanding debate in …
