48 pollen samples from Lake Khamra were prepared using the established protocol with added Lycopodium marker spore tablets. To store samples and prepare microscopic slides,...

The dataset comprises the results of measured total organic carbon (TOC, 53 samples), and for total nitrogen (TN, 30 samples) from sediment core EN20001, retrieved from Lake...

This dataset comprises the elemental distributions from high-resolution X-ray fluorescence (XRF) scanning from sediment core EN20001, retrieved from Lake Khamra, SW Yakutia. XRF...

This dataset comprises of the results of radiocarbon-based (14C) determination of age from sediment core EN20001, retrieved from Lake Khamra, SW Yakutia. Dating was conducted...

A total of 37 samples from sediment core PG2208 were analyses for diatoms, of which we found valves in 32 samples. For species analysis we prepared diatom slides for light...

To analyze the mineralogical composition of sediments we freeze-dried and milled 19 samples for X-ray diffractometry (XRD) using a PHILIPS PW1820 goniometer (40 kV, 40 mA, from...

Before conducting grain-size analysis, we treated 36 samples with hydrogen peroxide (30%), set on a platform shaker for 4–5 weeks to remove organic matter, while keeping the pH...

Core sections were opened alongside and cut into halves of which one was used for non-destructive XRF scanning and back-up material, while the other one was subsampled for...

To gain a composite core record for core PG2208 (Figure 1) we used XRF data, i.e., Sr, to correlate overlapping parts of retrieved sections resulting in 367 cm in total. For...

To gain information on organic matter variability we analyzed 204 samples for total carbon (TC) and nitrogen (N), 190 samples for total organic carbon (TOC), 45 samples for...

For sedimentary macroscopic charcoal analysis, 1 cm3 of wet sediment was dissolved in water, sieved through a 150-µm mesh. Under a stereomicroscope, macroscopic charcoal of...

Processed monosaccharide anhydrides records based on the raw data of sediment core JC11-K5 of Lake Czechowskie, N Poland using a robust Monte Carlo based approach that includes...

Processed charcoal records based on the raw data of sediment core JC11-K5 of Lake Czechowskie, N Poland using a robust Monte Carlo based approach that includes age and proxy...

A 3 m-long sediment composite record was retrieved from Laguna Vogt (46.74º S, central west Patagonia) using a UWITEC gravity corer (for the uppermost 70 cm depth) and a...

This data is an extension to the previously published data of Stoof-Leichsenring et al. (2024), including 23 additional measurements of total nitrogen (TN) from sediment samples...

The data compiles total mercury concentrations (THg, given in µg/kg) of 43 samples from the sediment core EN20001 of Lake Khamra. Measurements were carried out at the AWI...

The dataset includes diatom oxygen isotope data of 22 samples from the sediment core EN20001, Lake Khamra, covering the Holocene. Contamination assessment, conducted on purified...

The data includes total mercury concentrations (THg, given in µg/kg) of 22 samples from the core segment EN20001_6. Due to limited sample material, THg concentrations were...

The data contains biogeochemical data, including total carbon and nitrogen concentrations, as well as stable carbon (δ13C) and nitrogen isotopes (δ15N) of 21 samples from the...
