Lena River surface water monitoring near the Samoylov Island Research Station
Current warming, shifting hydrological regimes and accelerated permafrost thaw in the catchment of the Arctic rivers will affect their water biogeochemistry. The Lena River is... -
Measurements in soil and air at Samoylov Station (2002-2018), version 201908
This data set includes meteorological, soil, permafrost data obtained from the long term observational site Samoylov, located in the Lena River Delta, Siberia, between 1998 to... -
Near surface volumetric soil moisture and temperature measurements in the...
Four automatic stations measuring soil temperature and VWC were deployed in the central Lena River Delta, Siberia in August 2013 and retrieved in August 2014. They were... -
Colored dissolved organic matter (CDOM) absorption measurements of lakes in...
The datasets present measurements of cDOM absorption in lakesin the Lena River Delta during the summer periods from 2013-2016 and the spring periods from 2015-2016. Water... -
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... -
Soil and incubation data of permafrost-affected soils of the northeast...
The large amounts of soil organic matter (SOM) in permafrost-affected soils are prone to increased microbial decomposition in a warming climate. The environmental parameters... -
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... -
Temperature, water level and bathymetry of thermokarst lakes in the...
Thermokarst lakes are typical features of the northern permafrost ecosystems, and play an important role in the thermal exchange between atmosphere and subsurface. The objective... -
Water balance measurements on Samoylov Island during campaign Lena2011
The summer water balance of a typical Siberian polygonal tundra catchment is investigated in order to identify the spatial and temporal dynamics of its main hydrological... -
Measured water discharges, suspended supply and morphometric parameters of...
The datasets present hydrographic measurements on discharge and suspended supply in the Lena River Delta in the summer periods from 2002 to 2012. Water discharge was calculated... -
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... -
Hydrochemistry, water level, and discharge of water from Samoylov Island,...
Although ponds make up roughly half of the total area of surface water in permafrost landscapes, their relevance to carbon dioxide emissions on a landscape scale has, to date,... -
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... -
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.... -
Sedimentation and mineral analysis on sediment cores from the Lena Delta
Core and outcrop analysis from Lena mouth deposits have been used to reconstruct the Late Quaternary sedimentation history of the Lena Delta. Sediment properties (heavy mineral... -
Temperature time series and methane emission rates in the Lena Delta area
Frostmusterbedingte Seen sind ein wesentlicher Bestandteil der Polygonalen Tundren. Über ihre Bedeutung für die Methanemissionen dieser Gebiete ist bis heute nichts bekannt. Es... -
