Soil carbon and nitrogen data from Arctic river deltas
This data set contains the data for 1,571 soil samples from Arctic river deltas including %organic carbon, %nitrogen, bulk density, water/ice content and calculated carbon and... -
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... -
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... -
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.... -
Images from three time-lapse cameras at the center of Samoylov Island (2012...
Understanding permafrost processes and changes requires long-term observational datasets. Here we publish images from 3 time-lapse cameras installed at the center of Samoylov... -
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... -
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... -
Calm data at station Samoylov (2019)
Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the long-term... -
Soil data at station Samoylov (2020)
Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the long-term... -
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... -
Potential CO2 and CH4 production in the central Lena River Delta, Kurungnakh...
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... -
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... -
Dissolved organic carbon concentration of Lena River water from 11.04.2019...
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... -
Calm data at station Samoylov (2024)
Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the long-term... -
Calm data at station Samoylov (2023)
Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the long-term... -
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... -
Global soil and peat branched GDGT compilation dataset
Accurate temperature records for the deep geological past are a vital component of paleoclimate research. Distributional changes of branched glycerol dialkyl glycerol tetraether...
