Dataset specification

  • Title: GeoBasis Nuuk - Soil Properties - SoilEmpSa 30min
  • Description: SoilEmpSa is one of the three automatic soil stations in Kobbefjord. The station was established in 2008 and is placed on empetrum and salix vegetation (crowberry and willow) on the eastern side of the river on a south facing slope 40 m.a.s.l. The station (CR1000 logger) is running West Greenlandic Winter time (WGWT). Soil temperatures (thermocouple, 105T) and soil heat flux (hukseflux, HFP01) are logged every 30 minutes, while the soil moisture (Delta-T, ML2x) is logged every six hours (see SoilEmpSa 6h). Comments for 30 minute data: The station had a lot of problems with foxes destroying the sensors resulting in periodically missing data the first couple of years. In mid-August 2017 the cables for the thermocouples were dug free to check the depths of the sensors and hence, the measurements might be disturbed for a shorter period. Soil Properties:Soil Properties GeoBasis Nuuk: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:
