Biogeochemical properties of sediment cores from Barataria Basin, Louisiana, 2018 and 2019

Eleven soil cores (~2 m deep) were collected, one meter inland from the marsh edge, from four sites within Barataria Basin, LA, USA in Sept. 2018 and Aug. 2019. In addition, three soil cores (0.5 m deep) taken from the estuarine bottom 25 m offshore from the edge of a marsh site. During sampling, the depth of the estuary was 1 m relative to the marsh surface. The cores were sectioned into 10 cm intervals and analyzed for soil biogeochemical properties with depth.
