Summary

The goals of this project are to (1) measure exchanges of water vapor and greenhouse gases (CO2 and CH4) between the atmosphere and spatially-extensive ecosystems that occur in the Greater Everglades; (2) relate measurements of net ecosystem carbon exchange (NEE), gross ecosystem production (GEP), ecosystem respiration (R), and methane production to environmental controls including available water and energy; meteorological conditions; and/or plant physiological activity; (3) publish project results; and, (4) continue collaborations with Federal, State, and University researchers.

The project objectives are to:

(1) Measure exchanges of water vapor and greenhouse gases (CO2 and CH4) between the atmosphere and spatially-extensive ecosystems that occur in the Greater Everglades.
(2) Relate measurements of net ecosystem carbon exchange (NEE), gross ecosystem production (GEP), ecosystem respiration (R), and methane production to environmental controls including available water and energy; meteorological conditions; and/or plant physiological activity.
(3) Publish water, energy, carbon cycling and methane production data on the South Florida Information Access website (SOFIA), along with meta-data.
(4) Publish peer-reviewed journals.
(5) Continue collaborations with Federal, State, and University researchers.

Estimating carbon accumulation within restored Everglades will require empirical baseline data on the functioning of water, energy and carbon cycles. Baseline data on water, energy and carbon cycling also can help define and predict Everglades ecosystem response to regional (e.g., freshwater discharge) and global (e.g., air temperature and sea level rise) environmental change. However, measurements of carbon, methane, and surface-energy cycling are sparse over plant communities within greater Everglade's wetlands. Specifically, methane production and the quantity of carbon dioxide absorbed or released annually within subtropical forests and wetlands, as well as carbon cycling responses to changes in hydrology, salinity, nutrient loading, forest-fires and/or other factors are poorly known. This project proposes to leverage existing, eddy-covariance flux stations constructed by the South Florida Water Management District in the Big Cypress National Preserve for carbon cycling studies.
