Field data on methane fluxes, temperature, soil gas profiles and microbial...
Methane (CH4) production, oxidation, and emission were studied in ponds of the permafrost-affected polygonal tundra in northeast Siberia. Microbial degradation of organic matter... -
(Figure 3) Air temperature, humiditiy, wind speed, and radiation measured at...
This dataset is about: (Figure 3) Air temperature, humiditiy, wind speed, and radiation measured at the Samoylov climate station, 2009-07 to 2011-08. Please consult parent... -
Aerobic carbon dioxide production data of control and freeze-thaw...
We aerobically incubated soil samples from a polygon center (P1, 72° 22.5 N, 126° 29.4 E) on Samoylov, Northeast Siberia at 4°C for 60 days. We used three soil layers ((i)... -
Multi-angle and hyperspectral CHRIS-PROBA satellite data of the Island of...
CHRIS acquires a set of up to five images of each target during each acquisition sequence, these images are acquired when PROBA is pointing at distinct angles with respect to... -
Aerobic carbon dioxide production data of permafrost-affected soils of the...
We aerobically incubated soil samples from a polygon center (P3, 72° 22.5 N, 126° 29.4 E) on Samoylov, Northeast Siberia for 150 days. We used three soil layers ((i) surface... -
Baseline characteristics of climate, permafrost, and land cover from...
Samoylov Island is centrally located within the Lena River Delta at 72° N, 126° E and lies within the Siberian zone of continuous permafrost. The landscape on Samoylov Island... -
Anaerobic carbon dioxide and methane production data of permafrost-affected...
We anaerobically incubated soil samples from two polygon centers (P1: 72° 22.5 N, 126° 29.4 E, P2: 72° 22.3 N, 126° 29.9 E) on Samoylov, Northeast Siberia at 4°C for 150 days.... -
Visible and near-infrared orthomosaic and orthophotos of Samoylov Island,...
We obtained sub-meter resolution aerial images of Samoylov Island by mounting two Nikon D200 cameras on a helium-filled dirigible. Images were acquired in the visible (VIS) and... -
Land cover classification of Samoylov Island and Landsat subpixel water...
Ignoring small-scale heterogeneities in Arctic land cover may bias estimates of water, heat and carbon fluxes in large-scale climate and ecosystem models. We investigated... -
Colored dissolved organic matter (CDOM) absorption measurements of the Lena...
The datasets present measurements of cDOM absorption in channels of the Lena River in the Lena River Delta during the summer periods from 2013-2016 and the spring periods from... -
Meteorological observations and eddy covariance raw data from polygonal...
We present the first ecosystem-scale methane flux data from a northern Siberian tundra ecosystem covering the entire snow-free period from spring thaw until initial freeze-back.... -
Hourly meteorology and snow height at Samoylov met-station (2012-08-01 - 2013-06-30)
The Arctic Samoylov site is extensively described in Boike et al. (2013) and more shortly in Gouttevin et al. (2017) where the present dataset is exploited. Air temperature and... -
Land cover classification of polygonal tundra from small-format aerial...
Polygonal tundra on Samoylov Island (Lena Delta, Siberia) was mapped from small-format aerial photography. Sub-metre resolution aerial images were obtained by mounting two Nikon...
