Abstract:
This dataset provides geochemical measurements for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010. The data are presented as percentages (TOC, TN), ratio (C/N), ‰ relative to Vienna Pee-Dee Belemnite (δ13Corg), and ‰ relative to standard air (δ15N). All parameters are presented against both depth (m) and age (ka BP). The geochemical dataset provides information on Eemian lake ecosystem and catchment dynamics (Katrantsiotis et al., 2021). A total of 60 samples from the Eemian sediment sequence were freeze-dried, homogenised and weighed into tin capsules for analysis. TOC, TN, δ 13Corg and δ¹⁵N were quantified with a Carlo Erba NC2500 elemental analyzer coupled with a Finnigan MAT Delta V mass spectrometer at the Stable Isotope Laboratory, Stockholm University, Sweden. A previous version of this dataset can be found on the Bolin Climate Centre database (https://bolin.su.se/data/katrantsiotis-2021-sokli-1).
