Ground temperature timeseries (2014-2021) and cryostratigraphy from Villum Research Station, Station Nord, eastern North Greenland (81° N)

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.
