Gas Fluxes from and into Inland and Coastal Waters: Integrating Hydrodynamics and Biogeochemistry
Session ID#: 81270
Session Description:
It is critical to investigate the physical connections to the biogeochemical processes of transformation and transport through land and fresh and coastal waters to the atmosphere. Rates of lateral and vertical transport moderate timescales of loading, remineralization, mobilization, and release of climate forcing gases. Defining physical and biological controls on relevant emissions enables scaling for carbon budgets. Time series measurements of concentrations and fluxes coupled with meteorology and physical limnology/oceanography illustrate the importance of controls such as stratification, turbulent heat and momentum flux, ice cover, and mixing dynamics. Modeling and analytical capacities are keeping pace, while new tools and approaches allow results to be placed in the context of scalar variability within climate. We invite presentations examining linkages between measurements of gas emissions and physical forcings that define variability of fluxes from surface waters at local to regional scales.
