Abstract
Mangrove sediments store valuable evidence about carbon cycling and environmental changes in coastal ecosystems. In particular, the amount of inorganic carbon can highlight differences in carbonate inputs. The Wouri Estuary in Cameroon is a large tidal system where several rivers converge. However, the Wouri Estuary in Cameroon a large tidal system where several rivers converge has never been explored in this regard, particularly with respect to inorganic carbon preserved in mangrove sediments. In this context, we are trying to examines the distribution and potential sources of inorganic carbon in sediment cores from Koo Tidal Creek and the Dibamba River mangroves. The goal is to improve our understanding of the environmental conditions in these two ecosystems. Sediment core samples were collected at different Location, and the Loss on Ignition (LOI) technique was used to determine inorganic carbon content. The sediment was dried in the oven at 105°c for 42 hours. After they were heated in the muffle furnace for 4 hours at 550°C to burn the organic matter and finally heated at 950°c to determine the amount of inorganic Carbon. Inorganic carbon values in Dibamba mangrove ranged from 0.00% to 6.54%, with a mean of 3.69 ± 1.89, whereas Koo mangrove ranged from 3.31% to 9.03%, with a mean of 5.22 ± 1.74. The amount of inorganic carbon is virtually identical in both core sample sediments, although in the Koo core sample there is a peak of 49.52 at a depth of 44 cm, which may be due to a layer rich in carbonate, it may also due to an error while doing the measurments. This similarity suggests that both mangrove systems are subject to similar carbonate. These similarity are related to the sedimentary environments of the two mangrove systems. Overall, this study provides a baseline for understanding inorganic carbon distribution in these mangrove systems.
