Bring us your freshwater, ocean water, atmospheric, glacial, floodplain sediments, and soil organic matter fluorescent queries and challenges! With collaborators studying a vast array of environments, the time is now to communicate about chemical interpretations of fluorescent organic matter data. Small scales or large scales, we welcome any research projects utilizing fluorescence to chemically interpret organic matter in the environment. What kinds of challenges have you dealt with when working with fluorescence spectroscopy?
Please submit your abstracts today to AGU Session B073: Trials and Tribulations of Fluorescent Dissolved Organic Matter Chemical Interpretations: Converging Fluorescent Community Challenges Session ID#: 24003 Session Description: Understanding dissolved organic matter (DOM) chemistry has been a crucial focus of carbon cycling research in aerosol, aquatic, and terrestrial environments for decades. DOM is a critical currency for material and energy exchange among all systems, as well as an indicator of processes governing transformation through connected networks. Fluorescent DOM characterization by EEMs and subsequent interpretation by different quantitative methods, such as PARAFAC analyses, continues to be widely applied to identify underlying DOM chemistry. While the vast application of EEMs continues to grow, so do the challenges with interpretation. Oversimplification and overstatement of fluorescent DOM studies are common discrepancies, thus disputes over interpretations need to be resolved. We welcome fluorescent DOM studies from all environments, integrating results with other chemical analyses techniques, and also across multiple disciplines. Unifying fluorescent DOM communication by discussing diverse research, challenges, and interpretations are necessary, and will promote a clearer chemical understanding of Earth systems.
