title: Geochemical measurements for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010

description: 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).

title: Itrax data for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010

description: This dataset provides Itrax data for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010. Itrax values (counts per second) for selected elements are presented against both depth (m) and age (ka BP). Total number of kilocounts per step (kcps), MSE (mean square error), coherent and incoherent scattering data is presented as well. The Itrax dataset was used to provide information on Eemian landscape dynamics at Sokli (Plikk et al., 2016; Kylander et al., 2018). Elemental peak areas in the sediment succession were analysed with the X-ray fluorescence (XRF) core scanner at the Department of Geological Sciences, Stockholm University. The cores were scanned using a molybdenum-tube at 2 mm resolution (voltage 30 kV, current 45 mA) and 30 s measuring time. The peak areas for each step have been normalised by the total number of counts (kcps) for that step, in order to remove various instrumental effects. A previous version of this dataset can be found on the Bolin Climate Centre database (https://bolin.su.se/data/kylander-2018-sokli-1).

title: Counts of diatom valves for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010

description: This dataset provides counts of diatom valves for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010. Counts per taxon are presented against both depth (m) and age (ka BP); total sums for classes of diatoms (e.g. total benthic diatoms) and overall counts are presented as well. The diatom dataset provides information on Eemian lake ecosystem dynamics. A total of 104 samples were selected for diatom analysis. Diatoms were extracted from the sediment following the protocol presented by Battarbee et al. (2003). First, organic matter was oxidized in H2O2 in a water bath (at c. 100 °C). Subsequently, carbonates were removed by 10% HCl treatment (no visible reaction). Clay particles were decanted from 100 ml beakers after sedimentation overnight. Sand grains were removed after five seconds of sedimentation. The residue was mounted in Naphrax® and analysed under a light microscope with X1000 magnification using immersion oil. Flora used for species identification and information on ecological preferences are presented in Plikk et al. (2016; 2021). A minimum of 400 diatoms were identified from each sample with the exception of the bottommost samples where diatom abundance was very low. All analyses were performed in the laboratories Stockholm University, Sweden.

title: Relative abundances and concentrations of individual n-alkanes, total Concentration of odd n-alkanes, average chain length and the carbon preference index obtained from the Eemian sediment sequence retrieved from Sokli (Finland) in 2010

description: This dataset provides the relative abundances (Rel_abn) and concentrations (Conc; presented as ug/g dry weight) of individual n-alkanes, as well as the Total Concentration of odd n-alkanes (ug/g dry weight), average chain length (ACL) and the carbon preference index (CPI). The dataset consists of 59 samples obtained from the Eemian sediment sequence retrieved from Sokli (Finland) in 2010. All parameters are presented against both depth (m) and age (ka BP). The dataset provides information on Eemian vegetation and ecosystem dynamics (Katrantsiotis et al., 2021). Lipid extracts were obtained for a total of 59 samples and separated into different fractions following the laboratory protocol presented in Katrantsiotis et al. (2021). The hydrocarbon fractions were then analyzed by Gas Chromatography-Mass Spectrometry (Shimadzu-QP2010 Ultra system) for n-alkane identification and quantification. CPI was calculated as: CPI = SUModd/SUMeven; (ACL) was determined as: ACL = SUM(n * Cn)/SUM(Cn), where Cn is the concentration (mg/g dry weight) of odd chain n-alkanes. The analyses were carried out 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)

title: Trace metal data in the Amazon-Pará River estuary

description: The Amazon and Pará Rivers make up the largest and 5th largest rivers on earth, respectively, and converge in the Amazon-Pará Estuary. Prior to this dataset however, sparse trace metal data from this region were available. A GEOTRACES process study (GAPr11; cruise M147) was conducted on the RV Meteor during a period of high river discharge to study the flux and cycling of trace metals in this globally important region. Samples for dissolved (&lt;0.2 µm) trace metals (Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb) and Ra-228 were collected in the Amazon and Pará River estuary in April-May 2018. Using these data, we determined the flux and estuarine removal of trace metals from the Amazon and Pará Rivers into the Atlantic Ocean.

title: Biogenic silica (BSi) content for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010

description: The dataset provides quantifications of biogenic silica (BSi) content for the Eemian sediment sequence retrieved from Sokli (Finland) in 2010. Amounts of BSi are presented as percentage of weight and are presented against both depth (m) and age (ka BP). The BSi dataset provides information on Eemian lake ecosystem productivity (Plikk et al., 2016). A set of 898 1 cc sub-samples from the Eemian diatom gyttja has been analyzed using Fourier Transformed Infra Red Spectrometry (FTIRS) at the Department of Ecology and Environmental Science, Umeå University, Sweden, following Rosén et al. (2010). The analysis was performed on freeze-dried homogenized samples using a VERTEX 70 FTIR Spectrometer (Bruker Optics). All samples were pretreated in order to minimize the spectral variation not related to the sample properties. BSi content was quantified using an independent calibration model for BSi (Meyer-Jacob et al. 2014). Thirty samples were selected for conventional measurements of BSi content and used for validation of the model. The conventional measurements were made at the Alfred Wegener Institute for Polar and Marine Research (Bremerhaven, Germany).
