Rivers, representing the primary conduits of dissolved inorganic carbon (DIC) from the continents to the oceans, are important components to the global carbon cycle. To better understand the complex carbon cycling dynamics within two nested, mixed lithology watersheds, two sites were studied along the karst influenced upper Green River in south‐central Kentucky, USA. Weekly samples were collected from June 2013 through May 2014 and analyzed for δ13CDIC. The mixing model IsoSource was employed…

Results show that carbonate weathering and involved plant photosynthesis are the dominant processes controlling the riverine DIC contents under high discharge and temperature conditions.
Hydrological regulation of chemical weathering and dissolved inorganic carbon biogeochemical processes in a monsoonal river

Seasonal δ13CDIC sourcing and geochemical flux in telogenetic epikarst of south‐central Kentucky
Telogenetic epikarst carbon sourcing and transport processes and their associated hydrogeochemical responses are complex and dynamic. Carbon dioxide (CO2) transport rates in the epikarst zone are


Dissolved inorganic carbon export from carbonate and silicate catchments estimated from carbonate chemistry and δ 13 C DIC
Abstract. This work presents a study of the dissolved inorganic carbon (DIC) exchange associated with groundwater discharge and stream flow from two upstream catchments with distinct basement

Do carbonate karst terrains affect the global carbon cycle
Carbonate minerals comprise the largest reservoir of carbon in the earth’s lithosphere, but they are generally assumed to have no net impact on the global carbon cycle if rapid dissolution and
