CT54A:
Linking Optical and Chemical Properties of Organic Matter II Posters
Session ID#: 9252
Session Description:
During the last decade there has been a substantial increase in the number of studies using the optical properties (absorbance and fluorescence) of dissolved organic matter (DOM) as a proxy for its chemical properties in freshwater, estuaries and the coastal and open ocean. As a result progress has been made on finding the actual chemical compounds or phenomena responsible for DOM’s optical properties. Techniques such as ultrahigh resolution mass spectrometry have played an important role. However much requires further study. Spectroscopic measurements which are relatively easier to employ in synoptic and high resolution sampling of DOM distribution and dynamics offer unique insight to major advances in our understanding of organic matter cycling in all aquatic ecosystems. We invite talks and posters that specifically make connections between optical signals in absorbance and/or fluorescence and biogeochemical properties of freshwaters (lakes, rivers), estuaries and the coastal and open ocean. We encourage studies that describe DOM’s optical and chemical linkages at interfaces: terrestrial-aquatic, ocean-atmosphere, benthic-pelagic, dissolved-particulate, water-sediment, etc. We also welcome contributions that utilize remote sensing and in-situ monitoring to make connections between optical and chemical properties of organic matter.
