Globally, lakes are currently accumulating organic carbon (OC) at an estimated annual rate of about 42 Tg·yr. Most of the OC in all but the most oligotrophic of these lakes is autochthonous, produced by primary production in the lakes. The sediments of r eservoirs accumulate an additional 160 Tg annually, and peatlands contribute 96 Tg annually. These three carbon pools collectively coverless than 2% of the Earth’ s surface and constitute a carbon sink of about 300 Tg·yr. Although the oceans… CONTINUE READING
