SAM18-01 Samoylov permafrost drilling, Lena Delta, NE Siberia
Using a new 65 m long sediment core from the Lena delta apex (Samoylov Island), NE Siberia, this project uses a range of sediment and ground ice properties to help... -
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... -
Eddy-covariance and meteorological measurements of large pond and polygonal t...
To compare the carbon fluxes between semi-terrestrial tundra and ponds, which cover a significant fraction of northern peatlands, we installed a temporary Eddy Covariance tower... -
GDGT data in Siberian permafrost deposits
Core lipid GDGT distributions were studied in different North Siberian permafrost deposits to study GDGT diversity and underlying environmental controls. Samples represent... -
Slope failures at high elevation in the Italian Alps in the period 2000-2020
This dataset implements and updates with 106 new records the one published by Paranunzio et al. 2019 (doi:10.1594/PANGAEA.903761). The two datasets have the same survey... -
Stable water isotope composition and radiocarbon dates of permafrost ice wedg...
Seven profiles of permafrost ground ice (i.e. ice wedges) were sampled in 1999, 2007 and 2014 either by chainsaw or by ice screw at coastal bluffs east and west of the Zimov'e... -
Dissolved-gas concentrations, physical and chemical properties of 41 ponds as...
Ponds emit more methane per area than larger lakes. However, methane concentrations in and methane emissions from ponds show more spatial variability than larger waterbodies. A... -
