| Summary: | The stream discharges, dissolved silicon (DSi) concentrations, stable silicon isotopes, radon concentration, were measured on water samples taken in March, June, July, August and September 2019 in Lake 850, Northern Sweden. Additionally, total organic carbon (TOC), biogenic silica (BSi) concentrations, total nitrogen (TN) concentrations and carbon-nitrogen ratios (C/N), as well as concentrations of lead 210 (210Pb) were used for dating from the short sediment core, which was taken in March 2019 from the ice-covered lake are presented.All data were sampled to constrain the lake's recent water and silicon budget and to identify sources of dissolved silicon in the lake.Water samples for DSi and stable Si isotopes were sampled in HDPE acid-washed 125ml Nalgene bottles and filtered directly in the field through a 0.45μm Sterivex filter and further acidified using HCl to pH 2. Water samples for radon concentration measurements were samples in PET 2l bottles, where the water was let to overflow the bottle volume 3 ... |
