Mass balance model of carbon flow through the world’s mangrove ecosystems<br><p>Updated from Alongi, 2014. Units are Tg C a−1. The budget assumes a global mangrove area of 86,495 km2 (Marchand et al.2008). Solid blue arrows represent mean values based on empirical data. Dashed red arrows represent mean values estimated indirectly by difference. The Corg pool (both roots and soil) in soils to a depth of 1 m is presented as a box in the forest floor with units of Tg C. Unquantified inputs of dissolved carbon from land-derived groundwater and organic matter inputs from adjacent marine and catchments are not depicted. Abbreviations: GPP = gross primary production; NPP = net primary production; RAa = algal respiration; RC = canopy respiration; RS = soil respiration at soil surface; RWATER = waterway respiration; POC = particulate organic matter; DIC = dissolved inorganic carbon; DOC = dissolved organic carbon; CH4 = methane; EDOC = exchangeable dissolved organic carbon.
