Soil temperature is measured in 0, 10 and 30 cm under salix vegetation adjacent to the BioBasis plot Sal-6. The soil temperature sensors were installed in 2003. Temperature is recorded every hour all year round. Blank cells are missing data. Data from summer 2015 to summer 2016 is missing, due to erroneous data download. Data since 2016 exists, but is not made public in the database file, as there is extreme zero curtain drift. Soil properties:Soil properties GeoBasis Zackenberg:The GeoBasis monitoring programme focuses on selected abiotic characteristics in order to describe the state of Greenlandic terrestrial environments and their potential feedback effects in a changing climate. Monitored plot data is up-scaled to a landscape level and is used to improve ecosystem models to be able to quantify these feedback mechanisms. The GeoBasis programme provides an active response to recommendations in international assessments such as ACIA and SWIPA; and is continuously being adapted based on AMAP and other international founded recommendations. Furthermore, the GeoBasis programme is directly involved in several international networks and research projects (e.g. the Circumpolar Active Layer Monitoring (CALM) programme, the Nordic Centre of Excellence DEFROST, the Danish Centre of Excellence CENPERM, the EU-projects PAGE21 and INTERACT, and the Arctic Research Centre at Aarhus University). The GeoBasis programme is divided into a number of sub-groups, including:
