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...

These data represent five high-latitude sites studied in the PAGE21 project (https://www.page21.eu): Samoylov, Kytalyk, Abisko, Zackenberg and Bayelva. Please see the linked...

This study investigates a variety of lakes of different origin in the Siberian Lena River delta for lake hydrological, hydrochemical, and morpho- metric characteristics. The...

This dataset contains a point cloud, a digital terrain model (DTM), relative vegetation heights and the GNSS positions, derived from a terrestrial laser scanning (TLS) around...

This dataset contains time lapse pictures for the periode from 2006 to 2018, which shows the land surface in the area around the installed instruments of the related publication...

This data set is a compilation of mean annual ground temperature data measured in boreholes in the Global Terrestrial Network for Permafrost (GTN-P).

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...

Requirements for space based monitoring of permafrost features had been already defined within the IGOS Cryosphere Theme Report at the start of the IPY in 2007 (IGOS, 2007). The...

A compilation of basal dates of peatland initiation across the northern high latitudes, associated metadata including location, age, raw and calibrated radiocarbon ages, and...

Large amounts of organic carbon are stored in Arctic permafrost environments, and microbial activity can potentially mineralize this carbon into methane, a potent greenhouse...

We acquired more than 700 aerial images of snow covered polygonal tundra at the southern part of Samoylov on April 11, 2015. The images were obtained with a compact camera...

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...

About 50 locations ('cold spots') where permafrost (Arctic and Antarctic) in situ monitoring has been taking place for many years or where field stations are currently...

Thermal permafrost degradation and coastal erosion in the Arctic remobilize substantial amounts of organic carbon (OC) and nutrients which have accumulated in late Pleistocene...

High-resolution land cover mapping is needed in the heterogeneous arctic landscapes that change land surface parameters over a range of a few meters. Polygonal tundra on...

This dataset contains continuous time series of land surface temperature (LST) at spatial resolution of 300m around the 12 experimental sites of the PAGE21 project (grant...

Relative to the past 2,000 years, the Arctic region has warmed significantly over the past few decades. However, the evolution of Arctic temperatures during the rest of the...
