Data shows CH4 fluxes from the upper portion of cypress knees across various climate and flooding gradients of the North American Baldcypress Swamp Network in the Mississippi River Alluvial Valley. Climate data in the form of temperature, relative humidity, barometric pressure, and precipitation 3-days leading up to sampling date are also included. There various forms to calculate fluxes using cone and frustrum shapes that were compared to LiDAR scans fromi the field, therefore surface area and volume for each geometric shape is also included in the dataset.

This data release provides data for quantifying the aquatic export of total carbon in a cypress swamp within the Big Cypress National Preserve, and is part of a larger carbon budget study. The U.S. Geological Survey operated two continuous streamflow and water-quality monitoring stations within the Big Cypress National Preserve in southern Florida from September 2015 to October 2017. Site-specific regression models were developed using continuously measured specific conductance and concomitant discretely collected total carbon (dissolved organic carbon, dissolved inorganic carbon, and particulate carbon) samples to calculate continuous concentrations of total carbon. Total carbon loads were calculated by multiplying...
