Results from a laboratory-based investigation into sediment Silicon sorption capacities using standardized clay samples and the radioactive tracer 32Si

Abstract

These data are from a laboratory-based investigation into sediment Silicon sorption capacities using standardized clay samples (KGa-2 and SWy-3) and the radioactive tracer silicon-32 (32Si). Water for the project incubations was collected during the 2017 CLASiC Cruise (R/V Pelican PE17-20). Sampling spans sacrificial triplicate timepoints over 6 days. The data presented in this overall summary file include the location and depth of the water collection, which clay standard was used in each sample (KGa-2 vs. SWy-3), the salinity of the water used, sacrificial collection timepoint, initial radioactive tracer 32Si added to each individual sample, the final raw data for dissolved Si in solution, 32Si DPM found in the solution, and 32Si DPM found in the particles for each individual sample. The scope of the data was defined by the sampling scheme using triplicate sacrificial sampling over 6 days for the different clay types.
