    Description / Table of Contents: This atlas is an attempt to translate and consolidate the available knowledge on permafrost. It is a timely book suffused with the compelling enthusiasm of its authors and contributors. Close to a hundred individuals participated in its making, and it does a magnificent job at describing permafrost with maps, words, art, and stories. Far from being an academic product in the traditional sense, it gathers the knowledge from the voices of scientists, Indigenous Peoples, northern residents, and local practitioners to provide a holistic and inclusive view of today’s challenges in the “country of permafrost”.

    Description: This data set contains a first‐order estimate of distribution, thickness and ice-content of submarine permafrost on the Arctic shelf based on a numerical heat transfer model. Our model uses dynamic upper boundary conditions that synthesize Earth System Model air temperature, ice mass distribution and thickness, and global sea level reconstruction and applies globally distributed geothermal heat flux as a lower boundary condition. Sea level reconstruction accounts for differences between marine and terrestrial sedimentation history. Sediment composition and pore water salinity are integrated in the model. Model runs for 450 ka for cross‐shelf transects were used to initialize the model for circumarctic modeling for the past 50 ka.This data set consists of current sea levels, and permafrost depth [m below sea floor(m bsf)], total ice-content [m³ / m²] and enthalpy [MJ / m²] at times 50ka, 25ka and 0a before industrialization for 15892 locations on the Arctic shelf. Additionally zonations for permafrost depth and ice-content are given as layer files. Based on the undertaken sensitivity studies zones with 〈100m permafrost are uncertain, zones with 100-300m are probable, and zones with 〉300m are confident.

    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: Bottom water temperatures in lakes and the near-shore Arctic Ocean are usually below 4°C. If the water depth is shallow enough, the sea/lake ice freezes to the sea/lake bed and may significantly shift the mean annual temperature below zero. The temperature regime below the water is therefore directly dependent on the water depth and small changes can have a huge impact. Measurements of the sediment temperature below shallow water bodies, however, are scarce, and single temperature-chains in boreholes are not sufficient to map the spatial variability. As part of the testing phase of the MOSES project, we tested a new temperature lance to measure temperature profiles in lake sediments. The device is a 1.5m steel lance with 30 sensors at 5cm spacing that can be pushed or hammered into the sediment. The sensors equilibrate to the surrounding sediment or water within 10min, allowing for repeat measurements to cover the spatial variability. During the spring expedition to the Bayelva long-term observatory near Ny Ålesund, Svalbard, in March 2021, we measured the sediment temperature under the Brandallaguna and in the glacial lake Tvillingvatnet near the village of Ny Ålesund. The measurement at Tvilingvatnet was 16h long to allow for analysis regarding equilibration time.

    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.
