Figure 5. Example organic carbon profiles. Vertical lines mark the burial % organic C. (A) remineralization in upper section overlies buried % C; (B) constant % organic C indicates either a very high sediment accumulation rate or only refractory C at this site; (C) decline from surface to mid-point, with higher values below, indicates a change in the environment - it is unclear whether the % organic C reaches its burial value.
