Fig. 3: Inorganic influence on organic carbon accumulation and preservation.

a Bulk accumulation rates (BAR) versus organic carbon accumulation rates (OCAR) for the studied samples. Modern ocean data compiled by Schoepfer et al.36. Dashed lines represent the % of OC present in the sediment47. b Averaged BAR versus organic carbon preservation factor. (L95) dataset is based on satellite chlorophyll measurements, and the Oregon State (OS) dataset is based on in situ measurements using the 14C uptake method integrated over the depth of the photic zone and averaged by L95 oceanic province36. The preservation factor is dimensionless.
