Abstract: Studies investigating watershed carbon cycling have traditionally focused on high and middle latitude riparian watersheds. As a result, little information is currently available regarding watershed carbon dynamics of low-latitude watersheds dominated by peat-forming wetlands, such as the Florida Everglades, or the vulnerability of their extensive carbon stocks in a changing climate. In this three year project we will quantify above- and below-ground stocks and exchanges of carbon from terrestrial ecosystems along a seasonal hydrologic gradient in the headwaters region of the Greater Everglades watershed. Additionally, we will investigate the response of ecosystem carbon cycling to climate drivers to facilitate integration of our research findings with climate-driven terrestrial ecosystem carbon models to examine the potential influence of projected future climate change on regional carbon cycling. We will use a multidisciplinary array of ecological, hydrological, and geophysical sampling techniques combined with modeling at multiple spatial scales of measurement. Enhancement and expansion of current infrastructure for observation of regional carbon cycling coupled with initiation of new manipulative and process-oriented investigations of ecosystem carbon dynamics and their response to climate-related environmental drivers not only address near-term goals of understanding terrestrial carbon cycling in understudied subtropical and peatland ecosystems but also provides data products for integration with regional and global Earth Systems and Terrestrial Ecosystem Carbon models. Additionally, the proposed activities provide a research platform and baseline data for future investigation of the role of disturbance and climate forcing feedbacks on ecosystem carbon cycling in these vital components of the terrestrial carbon cycle. The infrastructure and data products developed by the proposed research will be leveraged with other regional AmeriFlux and NEON data networks and will be made openly available through the USGS SOFIA web data portal to promote the long-term objective of developing a comprehensive understanding of carbon cycling in the Greater Everglades watershed in a changing climate.
