Delta-X: Soil Accretion Rates from Cs-137 Activity and NUMAR Validation, MRD, LA
This dataset holds measurements of Cesium-137 (137Cs) activity sampled from sites in the Atchafalaya and Terrebonne Basins on the southern coast of Louisiana, USA.

Figure 1. Delta-X sampling sites along a salinity gradient (freshwater, brackish, and saline marshes) in an active and inactive coastal basin in Louisiana. Site CRMS-0294 is a floating marsh in an inactive basin. Samples for 137Cs testing were not collected at that site.
