Biogenic silica, lithology and elemental composition of piston sediment core Lake850-Core2-2019 from Lake 850, Sweden

DOI

Dataset includes depth and ¹⁴C based age-depth model of core from Lake 850 taken in March 2019. Biogenic silica, density, total organic carbon (TOC), total nitrogen content (%N) and calcium carbonate content (CaCO₃) were measured by weak-alkaline extraction, by constraining volume and weight of wet and dry bulk sediment sample and by elemental analyzed COSTECH, respectively. Further, stable carbon isotopes (d¹³C) were measured by Elemental Analyzer connected to a MAT-252 mass spectrometer at Weizmann Institute of Science, Rehovot.Mass accumulation rate (MAR) is calculated from sediment density, age-depth model and biogenic silica flux is MAR multiplied by biogenic silica content.Further, the data contains elemental composition (Al, Si, P, S, Ar, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ge, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Te, Ba, La, Ce, Nd, Sm, Eu, Tb, Er, Tm, Yb, Hf, Ir, Pt, Au, Pb, Rn och, Rh inc, MS) of the sediment core from 2019 originating from ITRAX CS37 XRF from GLOBE Institute, Copenhagen University.
