1:45 Facilitated Session—Are CDOM concentrations changing in Charlotte Harbor? If so, why?

 

2:20 Break

 

Session Two: What are the different methods of measuring CDOM concentrations? How do these help us to better understand quality and quantity of light in the region? How do the current monitoring protocols in southwest FL compare to other regions? Should the protocols in Charlotte Harbor be changed? How can data be better managed and shared?

 Moderator: ???

 

2:40 Tools for Observation of Synoptic Distribution of CDOM—other areas?

 (unconfirmed) Kendall Carder, Frank Muller-Karger, University of South Florida???

 

3:00 Overview of the current CDOM monitoring and lab analyses protocols in southwest FL

5:00 Posters and Conference Social

 

 

Wednesday, May 30 MORNING

 

8:45 Morning Reception

 

Session Three: What are the spatial-temporal components of CDOM in the Charlotte Harbor region? Can we obtain this information using existing data or do we need specific research project(s) or monitoring programs to obtain this information? Can landuse models be improved to better estimate CDOM “event mean concentrations” (EMCs)? Would this analyte be an important addition to models for resource management in the southwest Florida region? If specific studies/new instrumentation are needed, a brief description of these needs should be determined.
