The role of lake and reservoir sediments as sinks in the perturbed global carbon cycle



We estimate that recent increases in organic carbon accumulation in the sediments of lakes and reservoirs amount to about 0.02 ṁ 1015 gC yr−1 and 0.2 ṁ 1015 gC yr−1, respectively. The reservoir accumulation represents a small but significant fraction of the carbon missing in current global budgets.
