However, the magnitude of carbon stocks and the rate of carbon Carbon stock accumulation (CAR) vary geographically due to a large variation of local factors. In order to better understand Mangrove the blue carbon sink of mangrove ecosystems, we measured organic carbon stocks, sources and accumulation Organic carbon accumulation rates in three Indonesian mangrove ecosystems with different environmental settings and conditions; (i) a de- Stable carbon isotope graded estuarine mangrove forest in the Segara Anakan Lagoon (SAL), Central Java, (ii) an undegraded estuarine mangrove forest in Berau region, East Kalimantan, and (iii) a pristine marine mangrove forest on Kongsi Island, Thousand Islands, Jakarta. In general, Corg stocks were higher in estuarine than in marine mangroves, although a large variation was observed among the estuarine mangroves.
