M5 was located in a wet fen area called 'Rylek�ret', just 20 meters North of the Automatic Chamber site.
The station was in operation 2009 - 2017.
In this file soil temperatures in 2, 20, 30, 40 and 50 cm is recorded every 10th minute, using Campbell scientific T107 thermocouples.
Soil temperature is also measured in 2, 8, 12 and 16 cm depth, using East 30 Sensors, thermal conductivity sensors. Measurements from 00:10, 00:20, 00:30, 00:40 and 12:10, 12:20, 12:30, 12:40 are affected by the heat pulse the sensors are emitting at 00:00 and 12:00, in order to measure the thermal conductivity, which is given in the M5_720min file.
2017: Due to technical problems, the M5 station was terminated in August. 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:
