050: Linking the Optical and Chemical Properties of Dissolved Organic Matter in Natural Waters

Organizers: Christopher Osburn, North Carolina State University, closburn@ncsu.edu; Colin Stedmon, Department of Marine Ecology, National Environmental Research Institute, University of Aarhus, cst@dmu.dk; Robert G.M. Spencer, Woods Hole Research Center, rspencer@whrc.org

A paradigm in chemical oceanography is the remarkable similarity in the optical and chemical properties of both marine dissolved organic matter (DOM) and substantially degraded riverine DOM. Recently, in the oceanographic literature, a number of articles have reported on using combined optical and chemical techniques to investigate the sources and cycling of DOM in the coastal and open ocean water columns and in sedimentary pore waters. However, studies that calibrate the optical properties of DOM with geochemical measurements are few and far between in the literature. In addition, studies that attempt to resolve these properties with respect to rates of riverine DOM photochemical and biological degradation are also lacking. This session will provide a forum for scientists to exchange ideas and demonstrate progress in linking data-rich spectroscopic techniques, such as excitation-emission matrix fluorescence (EEMs) and spectral absorption, to geochemical measurements of DOM, such as elemental ratios, nutrients, stable isotopes, biomarkers, and structural characterizations arising from new developments in analytical techniques such as mass spectrometry and nuclear magnetic resonance spectroscopy.

Please let me know if you have any questions, we hope to see you in Salt Lake City!

Best wishes,
Chris
