Dissolved-gas concentrations, physical and chemical properties of 41 ponds...
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... -
Dissolved elemental and dissolved ion concentrations of Lena River water...
We collected water samples from the river surface in the center of the Olenekskaya Channel near Samoylov Island using a pre-rinsed HDPE 1 L bottle. During the open water period... -

Circumarctic seasonal measurements of permafrost parameters (thaw depth,...
The Permafrost Thaw Action Group is committed to the standardized field data collection necessary to quantify permafrost thaw dynamics across circumarctic regions. This effort... -
Chamber methane fluxes and active layer depths from a polygon in northeastern Siberia
This dataset contains in situ CH4 fluxes measured through the chamber technique over the growing season of 2015 (from July to September) at a wet polygon center and a dry... -
Carbon fluxes and further environmental data from the flood plain on...
The current assessments of the carbon turnover in the Arctic tundra are subject to large uncertainties. One of the reasons is the general shortage of flux data from the vast and... -
2023 myThaw data set
The 2023 myThaw data set provides standardized measurements for permafrost thaw and the linked parameters snow depth, vegetation height and water level as suggested by Boike et...
