Pollen records from Siberia are mostly absent in global or Northern Hemisphere synthesis works. Here we present a taxonomically harmonized and temporally standardized pollen...

In this dataset, we provide the age-depth model of a lake sediment core covering the last 28 thousand years from the Siberian forest-tundra ecotone. The age model provides...

Field investigations were performed in four areas forming a vegetation gradient from a treeless mountainous tundra (16-KP-04; Lake Rauchuagytgyn area) via tundra-taiga...

X-ray fluorescence (XRF) scanning data, scanned with an AvaaTech XRF core scanner at AWI in Potsdam. All elements were measured at X-ray voltages of 10 kV and 30 kV and currents...

Stable carbon isotopes of organic matter (d13C), measured with a Delta V Advantage Mass Spectrometer at the ISOLAB Facility of AWI in Potsdam. All isotopic values are reported...

Element composition including total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC), and total nitrogen (TN), measured with a soli TOC cube (Elementar) and...

This model was established based on the Bayesian method with a hiatus at 138 cm and calibrated using the IntCal20 dataset via the Bacon function in the R-package rbacon. A...

Radiocarbon dating performed on the total organic carbon content of 40 bulk sediments, measured at the MICADAS (Mini Carbon Dating System) Laboratory of AWI in Bremerhaven.

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...

The data compiles the results of radiocarbon dating. Subsamples (n=4) of the freeze-dried bulk material of the deeper part of the short core EN18232-1 were dated in the...

Data include inorganic carbon levels (TIC given in %), determined from all 39 subsamples of lake sediment short core EN18232-1. Prior measurements, freeze-dried aliquots were...

The data presents the results of dating by 210Pb and 137Cs. Freeze-dried subsamples of the short core EN18232-1 were analysed for 210Pb, 226Ra, 137Cs and 241Am by direct gamma...

The datafile presents total mercury concentrations (THg, given in µg/kg) of all subsamples (n=39) of sedimentary short core EN18232-1. All measurements were carried out at the...

The dataset includes diatom oxygen isotope data for 39 samples from short core EN18232-1, Lake Khamra, and corresponding key geochemical characteristics of the purified lake...

The dataset contains stable isotope data (δ18O and δD) from water, ice and snow samples of Lake Khamra received during two field campaigns in August 2018 and March 2020. Oxygen...

The data set presents more than 32,000 of about 40,000 trees, which were surveyed during several Russian-German expeditions by the North-Eastern Federal University Yakutsk and...
