“Whither goes mangrove-derived carbon” Mangroves exist in a critical zone between the land and ocean, and they sequester atmospheric CO2 at a rate higher than other ecosystems based on net primary production estimates. However, over 50% of the CO2 fixed by mangroves cannot be accounted for. This “missing sink” is ca. 0.1 Pg C y-1, and therefore represents a significant part of the global carbon budget. We hypothesize that this “missing sink” is due to the transformation of organic to dissolved inorganic carbon (DIC). Subsequently, this mangrove derived DIC either gets exported to the coastal ocean or goes into the atmosphere as CO2 via gas exchange. We examine this hypothesis by quantify the fluxes of organic and inorganic carbon to the coastal ocean and inorganic carbon across the air-water interface in order to determine the fate of CO2 sequestered by mangroves in Shark River, Florida, located entirely within Everglades National Park and situated in the largest contiguous mangrove forest in North America. -SEMINAR CANCELED-
