Sedimentation or accretion rates as a function of time at the sites a 1, b 2 and c 4. The rates are plotted as cm year⁻¹ (including, thus, a length unit) and as t ha⁻¹ year⁻¹ (including a weight unit; the depth- and thus time-dependent bulk density of the deposited/accreted material was taken into account). The dotted lines indicate the sedimentation or accretion rates if no degradation of mires had taken place
