This dataset contains ground temperature timeseries (2014-2021) and cryostratigraphy data from two 20 m deep boreholes located at Villum Research Station (VRS), Station Nord, eastern North Greenland. The cryostratigraphy data includes split permafrost core photographs and values for the following parameters: gravimetric moisture content, salinity, and freezing point depression. A complete sample inventory and information on sample quality and recovery is also included. Please read the file "Readme_Strandetal2021_V2" for the necessary background information and overview of the dataset contents (file structure and description of each file). This is the second version of the dataset; the ground temperature timeseries in this version are 2.5 years longer than in the first version, and meteorology data from the same period as the ground temperature data is provided. : The authors are grateful for the opportunity to collaborate with VRS on establishing permafrost monitoring as part of their climate monitoring program. When VRS was established in 2014, the permafrost researchers at UNIS were asked to establish the permafrost monitoring sites as the closest neighboring institution with a permafrost drill rig that could be transported by air to Station Nord. Wesley Farnsworth, Graham Gilbert, and Ullrich Neumann (Kolibri Geo Services) drilled the boreholes and collected the samples in August 2014. We would like to thank Luca Durstewitz for her sample preparation work (core cutting, cataloguing, and photographing) and initial lab analysis (gravimetric moisture content and sieving) during her internship at UNIS in spring 2019. Jørgen Skafte and Kirsten Christoffersen kindly assisted with downloading the borehole temperature data in summer 2019 and winter 2021. We would like to thank the Station Nord military personnel and the staff and researchers associated with VRS for helping with logistics and contributing to an excellent fieldwork and research environment. Prof. Henrik Skov has been particularly supportive of this project and ensured successful fieldwork in August 2017. This research received funding from INTERACT under the European Union H2020 Grant Agreement No.871120; this funding covered the summer 2017 fieldwork costs through INTERACT's transnational access program.
