    Patterns and drivers of riverine particulate organic carbon transport in an Andean valley by Clark, K, Kathryn E Clark

    Published 2014
    “…</p> <p>The source of POC in river suspended sediment samples was quantified using radiocarbon (Δ<sup>14</sup>C, ‰), stable carbon isotopes, and the nitrogen to carbon ratio. This revealed that river POC<sub>non-fossil</sub> was sourced from very young organic carbon in the valley (Δ<sup>14</sup>C ~50 ‰) and that POC<sub>fossil</sub> comprised 43 % of total POC. …”
