Investigating the physical as well as chemical connections between land and associated fresh and coastal waters is critical for understanding the dynamics of carbon in aquatic systems. Rates of lateral and vertical transport moderate time scales of loading, remineralization, mobilization, and release of climate forcing carbon gases (GHG). Defining physical and biological controls on climate relevant gas emissions enables scaling for carbon budgets. Time series measurements of concentrations and fluxes of GHGs coupled with meteorology and physical limnology/oceanography illustrate the importance of physical 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 variability within the climate system. Presentations are invited which examine linkages between measurements of GHG emissions and forcings that define variability of fluxes from surface waters at local to regional scales.
