Near real-time observations of snow water equivalent for SIOS on Svalbard – (SWESOS)

Julia Martin, Katharina Jentzsch, Niko Bornemann, William Cable et autres

Snow is an important component of the Svalbard permafrost and hydrological system due to its water storage and insulation properties. Continuous observations of snow properties in high-latitude such as Svalbard are almost non-existent, making it difficult to calibrate the current generation of …

Manual snow water equivalent measurements in 2020-2022 at the Bayelva station near Ny-Ålesund, Svalbard, Norway

Julia Martin, Frederieke Miesner, Niko Bornemann, William L Cable et autres

Understanding snow and permafrost processes and changes requires long-term observational datasets. This dataset adds manual measurements of snow water equivalent (SWE) and snow depth during the seasons 20/21, and 21/22 within the footprint of the automated SWE measurements at the Bayelva permafrost …

Soil data at station Bayelva (2019, level 1)

Julia Boike, Inge Grünberg, Stephan Lange, Niko Bornemann et autres

Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the Bayelva Site at Ny-Ålesund, Svalbard, where meteorology, energy balance components and subsurface observations have been made for the last 20 years. The …

Automated in situ measurements of snow water equivalent, snow depth, snow temperature and snow dielectric constant, at the high Arctic Bayelva site during the winter period 2019/2020

Katharina Jentzsch, Sebastian Westermann, Jean‐Charles Gallet, Niko Bornemann et autres

The high Arctic Bayleva site is located on western Spitsbergen about 3 km from the settlement of Ny Ålesund. The provided data set comprises snow water equivalent (SWE) and snow depth measurements recorded by automated sensors installed in August 2019 close to …

Snow water equivalent measurements at the Bayelva station near Ny-Ålesund, Svalbard, Norway (2019 et seq.)

Julia Boike, Frederieke Miesner, Inge Grünberg, Niko Bornemann et autres

Understanding snow and permafrost processes and changes requires long-term observational datasets. This dataset adds detailed snow measurements to the ongoing long-term monitoring efforts of meteorological and permafrost related variables at the Bayelva Site at Ny-Ålesund, Svalbard. We provide time series of snow …

A 16-year record (2002–2017) of permafrost, active-layer, and meteorological conditions at the Samoylov Island Arctic permafrost research site, Lena River delta, northern Siberia: an opportunity to validate remote-sensing data and land surface, snow, and permafrost models

Julia Boike, Jan Nitzbon, Katharina Anders, Mikhail N. Grigoriev et autres

Most of the world's permafrost is located in the Arctic, where its frozen organic carbon content makes it a potentially important influence on the global climate system. The Arctic climate appears to be changing more rapidly than the lower latitudes, but observational …

Samoylov Deep Drilling Spring Campaign 2018

Loeka L. Jongejans, Volkmar Assmann, Julia Boike, Dmitry Bolshiyanov et autres

Permafrost thaw is associated with impacts on climate, land surface and coastal and river bank structures. Pro-cesses such as thermokarst and thermo-erosion lead to ground subsidence, which can have drastic e˙ects on the topography. One of the main drivers of surface subsidence …
