Tuesday, May 29 AFTERNOON
Session One: 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 Florida compare to other regions? Should the protocols in Charlotte Harbor be changed? How can data be better managed and shared? Moderator: Frank Muller-Karger, University of South Florida
1:00 Tools for Observation of Synoptic Distribution of CDOM-Flow-through Measurements: Kendall Carder, University of South Florida
1:15 Tools for Observation of Synoptic Distribution of CDOM—Satellite Images: Frank Muller-Karger, University of South Florida
1:30 Overview of the current CDOM monitoring and lab analyses protocols in southwest Florida: Charles Kovach, Florida Department of Environmental Protection
1:45 Facilitated Session—Can any of these measurements help us better understand sources and sinks of CDOM? The composition of CDOM? Spatial and temporal variability in composition of CDOM? Should the protocols of measuring CDOM concentrations in southwest Florida be changed? If so, how?
2:20 Break
Session Two: 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: Peter Doering, South Florida Water Management District
2:45 Causes of Light Attenuation with Respect to Seagrasses in Upper and Lower Charlotte Harbor: L. Kellie Dixon, Gary J. Kirkpatrick, and Emily R. Hall*, Mote Marine Laboratory
3:00 Changes in Land Use in the Peace River Watershed and CDOM in the Lower Peace River Watershed and Upper Charlotte Harbor: Ralph Montgomery*, PBS&J and Sam Stone, PRMRWSA
3:15 Flow, source and CDOM in the Caloosahatchee River and Estuary: Peter Doering, South Florida Water Management District
3:30 Facilitated Session—Are CDOM concentrations changing in Charlotte Harbor? If so, why?
4:30 Summary of Next Day Activities: Catherine Corbett, Charlotte Harbor National Estuary Program
5:00 Posters and Conference Social
Wednesday, May 30 MORNING
8:30 Morning Reception
9:00 Opening Remarks: Catherine Corbett, Charlotte Harbor National Estuary Program, and Heidi Recksiek, NOAA Coastal Services Center
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. Moderator: Holly Greening, Tampa Bay Estuary Program
9:10 Near-shore water quality and seagrass relationships in the upper portions of Tampa Bay: Roger Johansson, City of Tampa
9:30 Temporal and Spatial Variability of CDOM Concentrations with Landuse: Robyn Conmy, University of South Florida
9:50 Examination of the spatial relationship of soils, landuse and slopes to florescence data in selected watersheds: An integrated analysis with GIS: Barnali Dixon, University of South Florida
10:10 Landuse, CDOM, and light attenuation along the river-estuary-ocean interface: Eric Milbrandt, Sanibel-Captiva Conservation Foundation Marine Laboratory
10:30 Break
Wednesday, May 30 AFTERNOON
Session Four: Should agencies be collecting additional information to better understand CDOM dynamics and landuse impacts on CDOM concentrations and composition? For landuse models? To quality of light reaching seagrass beds and impacting primary productivity? Can this information be added to current monitoring programs? Moderator: Judy Ott, Florida Department of Environmental Protection
1:00 Photoprotective Benefits of CDOM in Inshore Environments: Lore Ayoub, Paula Coble and Pamela Hallock-Muller, University of South Florida
1:20 Export of optically and compositionally distinctive DOM from tidal marshes in the Chesapeake Bay and effects of solar exposure on its spectral characteristics: Maria Tzortziou, NASA Goddard Space Flight Center- ESSIC/University of Maryland Smithsonian Institution
1:40 Facilitated Session-- Should agencies be collecting additional information to better understand CDOM dynamics and landuse impacts on CDOM concentrations and composition? For landuse models? To quality of light reaching seagrass beds and impacting primary productivity? Can this information be added to current monitoring or research programs? If specific studies/new instrumentation are needed, brief description of these needs…
2:40 Break
3:00 Facilitated Session— Can or should we add CDOM to our management strategies? How? Can we add “quality of light” to our water quality targets? Remaining questions.
