Short summary
Mangroves take up more carbon (C) than any other ecosystems, but > 50 % of this C is missing. The forest loses organic C to the surrounding waters, which might be rapidly transformed into inorganic C. Previous studies focused on organic C could have missed this important sink. We examined the sources and sinks of dissolved C in two mangrove estuaries, and confirmed that ca. 90 % of the total dissolved mangrove-derived C flux flowing out of the estuaries was inorganic C.
