Abstract
Soil cores were collected at wetlands that had been restored for a minimum of 10 years with managed hydrology in Twitchell and Sherman Islands in the western portion of the Sacramento-San Joaquin Delta, California. The goal of the study was to measure soil carbon accumulation rates since restoration for comparison with multiyear net atmospheric carbon exchange measured by eddy covariance towers. Soil cores were sliced at 1 to 3 cm-thick intervals and analyzed for bulk density, organic matter, organic and inorganic carbon, total nitrogen and their stable isotopes, and 210Pb specific activities. Emergent vegetation was present at the sites. Dominant species at the core locations included Schoenoplectus acutus, Typha sp, and Phragmites sp. This dataset accompanies the paper Arias-Ortiz et al. under consideration in JGR: Biogeosciences.
