This study evaluated the net ecosystem exchange of CO2 and CH4 from experimental wetland mesocosms established in elevated CO2 and ambient CO2 glasshouses at the U.S. Geological Survey’s Wetland and Aquatic Research Center (Lafayette, Louisiana). The study duration was approximately two years, and these data represent measured and calculated data from four time points, which the investigators associate with season.

This dataset includes fine root productivity data that were estimated via two techniques (serial coring and root in-growth bags) in tidal freshwater wetlands and adjacent oligohaline marshes in coastal South Carolina and Georgia from March 2016 through October 2017.

In 1996, 400 tree-centered plots were established by first randomly choosing x- and y- coordinates from an imaginary grid overlaying the study area. Each random point was also randomly assigned a tree-size category from a pre-determined sampling scheme. The scheme was to include 20 trees from each of 5 size categories. Size/height categories were: less than 0.1m, 0.1-1m, 1-2m, 2-3m, and greater than 3.0m. To avoid excessive aggregation of samples, no more than 5 trees in a size class could be chosen within a 100-meter sub-area of the sampling grid. The nearest tree to each random point that met the pre-determined size requirement was identified and marked with a permanent aluminum tag. For the size category less...
