Session ID#: 11337
Session Description:
Transfer of carbon across the terrestrial-marine boundary and carbon cycling within estuarine and coastal waters are important components of the global carbon cycle. Yet carbon and its transformations in coastal environments remain poorly characterized. Estuaries have complex physical drivers and geochemical gradients that are coupled to watershed hydrology, tidal cycles, and extreme events (e.g., floods, droughts). Understanding the interactions of organic carbon in these environments, particularly in the context of global change, requires multiple observational approaches for identifying sources and ages, exchange mechanisms, transport pathways, and process time scales. We invite contributions that examine the dynamics of particulate and dissolved organic carbon in estuarine and coastal systems and how those processes mediate the transfer of carbon from land to sea and between the water column and sedimentary environments.
Possible topics include: transport of organic matter across the terrestrial- marine interface, partitioning of organic matter between particulate and aqueous phases, exchange between dissolved and particulate components, oxidation and burial in sediments, linkages between organic matter dynamics and nutrient cycling, response to seasonal variations and discharge perturbations, age determinations, biomarker and isotopic studies, as well as modeling approaches to carbon dynamics.
