Understanding the Importance of Blue Carbon

Although the term blue carbon has been created around two decades (Lovelock and Duarte, 2019, Nelleman et al., 2008), scientists have already started to do research on the carbon cycle hundred years ago (Falkowski et al., 2000). Blue carbon mainly includes organic and inorganic carbon that can be absorbed and stored by coastal and marine ecosystems (Lovelock and Duarte, 2019, Wedding et al., 2021). In blue carbon ecosystem, people usually mention salt marshes, mangrove, and seagrass. Macroalgal ecosystem was not added to blue carbon system in the really beginning (Mcleod et al., 2011). Although macroalgal has limitation in the storage in sediment in situ due to the place the often grows on, macroalgal also play the vital role in blue carbon as carbon donor in other ecosystems (Raven, 2018, Hill et al., 2015). In addition to blue carbon, there are other color of carbon. For example: green carbon, which can also sequester carbon; black carbon, which was highly condensed carbonaceous residue from incomplete combustion processes (Middelburg et al., 1999). Compared with forests on land, mangroves, seagrass grasslands, tidal swamps, etc. in marine ecosystems, can absorb and store more carbon per unit area. […]
