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

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.

本数据集源自一项针对沉积物硅吸附容量的实验室研究，实验采用标准化黏土样品（KGa-2与SWy-3）以及放射性示踪剂硅-32（32Si）开展。本实验培养环节所用的海水采集自2017年CLASiC科考航次（R/V Pelican PE17-20）。本次采样在6天周期内设置了多组牺牲式采样时间点，每组均采集三份重复样品。本汇总文件所呈现的数据涵盖以下内容：水样采集点位与水深、每份样品使用的黏土标准品类型（KGa-2或SWy-3）、实验用水的盐度、牺牲式采样时间点、向每份独立样品添加的初始放射性示踪剂32Si剂量、溶液中溶解态硅的最终原始检测数据、溶液中检出的32Si每分钟衰变数（DPM），以及颗粒相中检出的32Si每分钟衰变数（DPM）。本数据集的覆盖范围由采样方案限定：针对不同黏土类型，在6天周期内开展三组重复的牺牲式采样。
