| contents | This dataset provides geochemical measurements for the Holocene sediment sequence retrieved from Lake Loitsana (Finland) in 2008. The data are presented as percentages (Corg, N), ‰ vs PDB (δ13Corg) and ‰ vs air (δ18O). All parameters are presented against both depth (cm) and age (cal yr. BP). Two age/depths models are presented: the first model represents the original age/depth model applied to the records (Shala et al., 2014; 2017) and the second age/depth model, which is the author-preferred version, presents updated age-estimates derived using the r package 'Bacon' (Blaauw and Christensen, 2011). The geochemical dataset provides information on Holocene lake ecosystem and catchment dynamics. A total of 144 samples from the Holocene sediment sequence were freeze-dried, ground and weighed into tin capsules for C/N-analysis. Additional material was taken from each sample for organic carbon (Corg) analysis. The material was weighed into silver capsules, treated with HCL (10%) and dried overnight before analysis. Concentrations were measured through combustion in a Carlo Erba NC2500 Elemental Analyzer at the Stable Isotope Lab at the Department of Geological Sciences, Stockholm University. |
