Organic matter degradation, effects preservation

Use the simple model approach from Figure 12.12 and the general values given (5 = 85%, cp = 2,5 g cm= 500 yr) to calculate the degree of organic carbon preservation when accumulation rates are 1 and 0,1 (mg cm yr ) for NRP and, respectively, and a reactive mixed layer of 10 cm thickness. Please consider that the degradation of organic matter has an effect on the sedimentation rate (co).
