Bulk soil stable isotope compositions and elemental concentrations measured f...

Bulk soil stable isotope compositions (δ¹³C, ‰ vs. VPDB; δ¹⁵N, ‰ vs. air N₂) and elemental nitrogen and carbon concentrations (N%, C%, C:N ratio) measured at during different...

Nitrous oxide isotopologue signatures measured from static chambers in smallh...

N₂O isotopologue signatures – including bulk δ¹⁵N (‰ vs. air N₂), intramolecular site preference (δ¹⁵N^SP = δ¹⁵Nα − δ¹⁵Nβ, ‰), and δ¹⁸O (‰ vs. VSMOW) – measured from headspace...

Particulate organic carbon measurements during 24-days of incubations in meso...

Six mesocosm experiments with specimens of Fucales or Laminariales were conducted across six georegions (3 mesocosms with brown algae, 3 mesocosms without brown algae)....

Organic carbon (OC) content, nitrogen content, C/N ratio, carbonate content, ...

The grain size of sediments was determined with a Cilas 1180 laser-diffraction particle analyzer (range 0.04–2500 μm) and the mean grain size was calculated. The surface area...

Basic sedimentary characteristics from permafrost cores from the Noatak, Kobu...

This data set describes the soil core and sample characteristics from soil cores collected in the Noatak (67.03 N; -162.45 E), Kobuk (66.79 N; -161.37 E), and Selawik (66.58 N;...

Element composition of sediment core EN21103 from Lake Ulu, eastern Siberia

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...

Total inorganic carbon (TIC) from sediment short core EN18232-1 of Lake Khamr...

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...

Below-ground carbon stocks and soil properties in the central Lena River Delt...

Arctic warming increases the degradation of permafrost soils but little is known about floodplain soils and other permafrost soils in the permafrost region. This dataset present...

Sedimentology data from a polygonal tundra landscape near the WWF station Kyt...

Patterned ground of the polygonal tundra yields sensitive indicators of environmental and climate change. Polygon ponds, mires and cryosoils are typical components of Arctic...

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...
