The U.S. Geological Survey is offering a funding opportunity to a CESU partner to assist in developing datasets for predictive relationships between florescence of dissolved organic matter (FDOM) and dissolved organic carbon (DOC) in freshwater types of SE Alaska. Surface water from large rivers is currently being collected and characterized, but from a limited variety of water types. Assistance in developing continuous monitoring surrogates and documenting the relationship between surrogates and measured water quality parameters, such as FDOM and dissolved carbon and organic matter, is sought. These studies will augment and inform current USGS efforts at characterizing dissolved carbon in glacially dominated large rivers and help evaluate USGS standard methods to new water types. It will also foster a collective understanding of the DOC concentrations and characteristics of SE Alaska streams and inform their sensitivity to pollutants.
