Tuesday, May 29 AFTERNOON
Session One: General overview of CDOM in Estero Bay, Charlotte Harbor and Lemon Bay and the tributaries to each, including impacts to quality and quantity of light reaching seagrass beds and influencing primary productivity. Are CDOM concentrations changing in the region? If so, why?
Moderator: Kellie Dixon, Mote Marine Laboratory (unconfirmed)
1:00 CDOM Contributions to Light Attenuation and Light Quality in Charlotte Harbor
Kellie Dixon, Mote Marine Laboratory
1:15 Peace River CDOM Concentration Changes due to Landuse Changes.
Ralph Montgomery, PBS&J
1:30 Caloosahatchee River CDOM Concentrations Changes due to Rainfall Patterns
Peter Doering, South Florida Water Management District
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
Charles Kovach, Florida Department of Environmental Protection
3:20 Facilitated Session—Should the protocols of measuring CDOM concentrations in southwest Florida be changed?
4:30 Summary of Next Day Activities.
Catherine Corbett, Charlotte Harbor National Estuary Program
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.
