Fig. 3: Relative radiocarbon (14C) age offsets (in 1000 years-ka) between organic matter (OM) fractions and bulk organic carbon (OC).

Fig. 3

The different OM fractions are shown as colored triangles (green for free particulate OM–fPOM; orange for occluded particulate OM–oPOM; dark gray for mineral-associated OM-MAOM<6.3µm) and bulk OC is shown as filled black square symbol. All results are normalized to the ages of the MAOM<6.3µm fraction. The bulk OC of the two deep samples in L14-02 revealed infinite 14C ages and were excluded from this figure.
