Emmanuel Boss Speaks About Water-Column Optics in St. Petersburg, FL
Emmanuel's first talk addressed "Particulate and Dissolved Properties Inferred from in situ Optical Measurements." This presentation served as a general introduction to the utility of bulk optical measurements in elucidating processes and properties of interest to the USGS. Richly illustrated with data from Emmanuel's own research in a wide variety of environments, this talk was well attended by a diverse crowd from not only CCRMS but also the USF's College of Marine Science and the USGS' Water Resources office in Tampa. Emmanuel's second talk, hosted by Ken Carder of the USF's College of Marine Science, focused on "Effect of Bottom Substrate on Inherent Optical Properties: Evidence of Biogeochemical Processes." In this talk, Emmanuel presented his recent work with the U.S. Navy's Coastal Benthic Optical Properties field experiment at Lee Stocking Island in the Bahamas. There, Emmanuel and his colleagues found that inherent optical propertiesmeasures of how the seawater and materials in it scatter and absorb lightcan vary widely and depend on bottom type (for example, sea grass versus coral reef). This finding has important implications for USGS efforts to model the underwater light field and to interpret remotely sensed images of submerged bottoms. We look forward to more of Emmanuel's high-energy research!
