Dissolved carbon biogeochemistry and export in mangrove-dominated rivers of the Florida Everglades

Abstract: Abstract. The Shark and Harney rivers, located on the southwest coast of Florida, USA, originate in the freshwater, karstic marshes of the Everglades and flow through the largest contiguous mangrove forest in North America. In November 2010 and 2011, dissolved carbon source-sink dynamics was examined in these rivers during SF 6 tracer release experiments. Approximately 80 % of the total dissolved carbon flux out of the Shark and Harney rivers during these experiments was in the form of inorganic carbon, either… Show more

“…Biogeochemical cycling and property distributions in aquatic systems, including in lakes, estuaries, and ocean basins, depend on water transport paths and timescales. Analysis of transport paths and timescales has been used to estimate ventilation rates (Jenkins, 1987;England, 1995;Hohmann et al, 1998;Cao et al, 2009), to describe circulation and mixing (Fine, 1995;Haine et al, 1998;Schlosser et al, 2001;Wunsch, 2002), and to investigate river plume dynamics (Zhang et al, 2010(Zhang et al, , 2012. These analyses can either be the focus of or complement investigations into biogeochemical processes.…”

“…In the Hooghly-Sundarbans system, [DIC] -[DOC] correlation was not significant (Sundarbans: p = 0.29, Hooghly: p = 0.16) suggesting limited role of phytoplankton production on the estuarine DOC level. In contrast to the Hooghly (p = 0.56), significant positive correlation between pCO2 and [DOC] was observed in the Sundarbans (p = 0.02, n = 11) suggesting analogous sources of pCO2 and DOC within the system, possibly through pore-water exchange from adjacent mangroves to the estuary as reported from other mangrove systems worldwide (Cai et al, 1999, Ho et al, 2017. (Sundarbans: p = 0.85, Hooghly: p = 0.40) as well as pCO2- [DOC] relationships (described earlier).…”
