Use of 14C and 13C natural abundances for evaluating riverine, estuarine, and coastal DOC and POC sources and cycling: a review and synthesis
PA Raymond, JE Bauer - Organic Geochemistry, 2001 - Elsevier
Though not typically regarded as “biomarkers” in the traditional sense of the word, the
radioactive and stable isotopes of carbon (14C and 13C, respectively) can serve as powerful …

Radiocarbon‐based circulation age of the world oceans
K Matsumoto - Journal of Geophysical Research: Oceans, 2007 - Wiley Online Library
The distributions of deep ocean Δ14C data are often used to illustrate the rate of deep ocean
circulation. The associated conventional 14C ages show a difference of 1000 years between …
