Diatom distribution in sediment core PG2208

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...

Mineral composition of sediment core PG2208

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...

Grain size composition of sediment core PG2208

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...

Elemental composition of sediment core PG2208

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...

Age determination of sediment core PG2208

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...

Organic geochemistry of sediment core PG2208

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...

Pollen data of permafrost sediments from Batagay megaslump, Yakutia

In this dataset, we provide pollen counts of 5 permafrost sediment samples from the Batagay megaslump, Yakutia. For each sample, 2.85-4.58 g of wet sediment was taken for pollen...

SiDroForest: Synthetic Siberian Larch Tree Crown Dataset of 10.000 instances ...

This synthetic Siberian Larch tree crown dataset was created for upscaling and machine learning purposes as a part of the SiDroForest (Siberia Drone Forest Inventory) project....
