2:40 PM Refreshment Break – participants move to working group discussion meeting rooms
3:00 PM Location-based Working Groups
(Participants break out into three working groups, where they will view poster presentations and engage in discussion with the goal of identifying emerging issues and future priorities.)
Working Group One: Headwaters (Kissimmee, Lake Okeechobee) – [Egret Room]
Moderator: Ross Hinkle, University of Central Florida, Orlando, FL
Poster Presentations
Carbon-Dioxide and Methane Fluxes in Central Florida Wetlands -- Scott Graham, National Institute of Water and Atmospheric Research, New Zealand
Carbon Dynamics on a Large Conservation Preserve in the Northern Everglades Watershed -- Ross Hinkle, University of Central Florida, Orlando, FL
Energy-Budget Evaporation at Lake Okeechobee -- Mike Wacker, US Geological Survey, Davie, FL
Urban NEE Drivers and Patterns in the Headwaters of the Everglades -- Elizabeth Becker, University of Central Florida, Orlando, FL
Using Hydro-Geophysical Methods to Investigate Carbon Dynamics in Wetland Soils of the Northern Everglades Watershed -- Matt McClellan, Florida Atlantic University, Davie, FL
Working Group Two: Central Everglades (WCAs, Loxahatchee, Ag) – [Fairway Room]
Moderator: Brian Benscoter, Florida Atlantic University, Davie, FL
A series of concept-map posters highlighting known dynamics and knowledge gaps in Central Everglades carbon cycling will be presented based on contributions from Working Group participants. These concept maps will serve as a framework for discussion to refine, focus, and prioritize key topics for improving carbon cycle representation of the Central Everglades.
Working Group Three: Southern Everglades  – [Flamingo Room]
Moderator: Vic Engel, US Geological Survey, Gainesville, FL
Poster Presentations
DOC Loads to Everglades National Park from Tamiami Canal at S12-D -- Travis Knight, US Geological Survey, Fort Myers, FL
Investigating Spatial Variability in Gas-Flux Dynamics within Big Cypress National Preserve, Florida Using Hydrogeophysical Methods -- Matt Sirianni, Florida Atlantic University, Davie, FL
A Framework for Quantifying Carbon Uptake for the Entire Everglades - "it takes a village" -- W. Barclay Shoemaker, US Geological Survey, Davie, FL
4:20 PM Working Group Discussion Concludes – Participants Reassemble in Ibis Room
4:30 PM Concluding Remarks by Working Group Moderators
(Remarks will focus on emerging issues and wish lists identified for each geographic area.)

Topics include:

(1) Atmospheric exchanges of greenhouse gases measured with soil gas-traps and eddy-covariance methods;

(2) regional-scale remotely sensed carbon uptake rates;

(3) Lateral hydrologic fluxes of dissolved/particulate organic/inorganic carbon within key drainage features;

(4) The role of fire, hydro-period and hurricanes in long-term net radiative forcing;

(5) Geologic and geophysical delineation of peat soil thickness and historic changes in thickness; and

(6) Soil oxidation/preservation strategies such as hydration and flooding.

Lessons learned from similar wetlands studies are welcomed for discussion of possible transfer-value to the greater Everglades. Finally, location-based working groups (headwaters, central, and southern Everglades) will be assembled to discuss scientific posters and identify emerging issues and priorities for future study.

Workshop Benefits:

At the conclusion of the workshop, attendees will have a better understanding of the historic, current and future state of water, energy and carbon cycles within the Greater Everglades. Workshop findings will be used to identify emerging issues and research priorities.
