Dataset specification
- Title: GeoBasis Nuuk - Soil Properties - SoilFen SoilWaterChemistry
- Description: SoilFen is one of the three automatic soil stations in Kobbefjord. Data from the station is found under Meteorology (air temperature, relative humidity and PAR) and Soil Properties (soilwater chemistry, soil temperatures, soil heat flux). The station was established in 2007 and is placed in the moist fen 40 m.a.s.l. close to the InteractFen (Meteorology, Soil Properties, Snow Properties), the EddyFen and the Methane station (Fluxmonitoring). Six soil water samplers (suction cup lysimeters, Prenart Super Quartz) are installed at 10 and 80 cms depth (three replicates at each depth) next to the automatic station "SoilFen". The soil water samples are collected manually during the summer field season (app. May-October) and analyses are done at the Department of Geosciences and Natural ressource Management (IGN) and at the Department of Biology, both University of Copenhagen, Denmark and in the laboratory at the field station in Kobbefjord. 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:
