    Description: This dataset contains CTD measurements, taken together with temperature measurements in March 2021 at Brandallaguna and the glacial lake Tvilingvatnet near Ny Ålesund, Svalbard. Data was recorded using a CastAway-CTD that was manually lowered to the bottom of the lake or lagoon at the measurement sites and contains information about water conductivity, temperature and depth, as well as the GPS position.

    Description: This data set contains quality controlled soil temperature and volumetric liquid water content measurements from a site at the forest-tundra transition in the western Canadian Arctic. The measurement site is near by the Trail Valley Creek (TVC) research station, which is operated by Wilfried Laurier University. The station is located east of the Mackenzie Delta and 45 km north of Inuvik. The published data set provides long-term observations on the thermal and hydrological state of the active layer at a hummocky tundra site within the continuous permafrost zone. The station consists of a soil depth-profile with four sensor sets at 2cm, 5cm, 10cm, and 20cm of paired soil moisture and soil temperature sensors. Additionally, three distributed soil moisture sensors are installed in the surface soil. The data series is continued since 2016 and provides a basis for process understanding and modelling studies of Arctic permafrost.

    Description: Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the long-term observational site Samoylov, located in the Lena River Delta, Siberia (72.37°N, 126.48°E). The location is characterized by a cold, dry tundra climate with mean annual air temperature of -11.7°C (using years with complete data between 1998 and 2017). The monthly mean temperatures over this period varied between 9.4°C in the warmest month (July) and -31.7°C in the coldest month (February). The average summer rainfall (June-October) was 145.2 mm. This dataset adds recent years to the observations of meteorological parameters, energy balance, and subsurface observations which have been recorded since 1998. The instrumentation, calibration, processing and data quality control is explained in Boike et al. (2019). The data provide observations of temporally variable parameters that mitigate energy fluxes between permafrost and atmosphere, such as snow depth, snow temperature, liquid precipitation, water level, air temperature, relative humidity, wind speed and direction, atmospheric pressure and radiation fluxes. The observations are suitable for use in integrating, calibrating and testing permafrost as a component in Earth System Models. The resulting quality-controlled dataset is unique in the Arctic and serves as a baseline for future studies.

    Description: This dataset contains CTD measurements, taken together with temperature gradient or gas concentration measurements in September 2021 at 53 locations off Tuktoyaktuk Island and in a small lake (“Lake 3”) between the villages of Tuktoyaktuk and Inuvik, as well as in a former river channel (“Swiss Cheese Lake”) in the Mackenzie Delta, Northwest Territories, Canada. The measurements were part of the “Mackenzie Delta Permafrost Field Campaign” (mCan2021) within the “Modular Observation solutions for Earth Systems” (MOSES) program. Data is recorded using a CastAway-CTD that is manually lowered to the bottom of the lake or ocean at the measurement sites and contains information about water conductivity, temperature and depth and GPS position. Especially the water temperature and conductivity/salinity are important for gas concentration data processing. The data is provided as unprocessed raw data.
