This data release contains data from cores collected in marshes and in sediments under invasive Brazilian waterweed (Egeria densa Planchon) in the Sacramento-San Joaquin Delta of California during the spring of 2018. Data are provided in two text files in comma separated columns. The first Core_Sites_Details.txt contains core site location, collection dates, and naming information. The second file, Core_Section_Analyses.txt contains % organic carbon, % inorganic sediment, bulk density data for each 2-cm section of six peat cores collected in marshes and six sediment cores collected under patches of Brazilian waterweed. Additionally, the second file contains the radioisotope values (137Cs and 210Pb) for each of the cores. Cores were collected at three Delta study sites: Lindsey Slough, Mokelumne River, and Middle River in the Delta.
