Carbon accumulation and storage capacity in mangrove sediments three decades after deforestation within a eutrophic bay

Abstract A dated sediment core from an eutrophic mangrove area presented non-significant differences in carbon accumulation rates before (55.7 ± 10.2 g m − 2  yr − 1 ) and after three decades of deforestation (59.7 ± 7.2 g m − 2  yr − 1 ). Although eutrophication effects appear to compensate the loss of mangrove organic matter input, the results in this work show a threefold lower carbon accumulation than the global averages estimated for mangrove sediments. The effects of increasing eutrophication and enhanced sediment dry bulk density observed after deforestation (~ 30% higher) did not result in higher carbon stocks. Moreover, the lower TOC:OP (
