The EddyFen station measures carbon dioxide fluxes via eddy covariance method in the wet fen site (40 m.a.s.l) close to the Methane (Flux Monitoring), InteractFen (Meteorology, Soil Properties, Snow Properties) and SoilFen (Meteorology, Soil Properties) stations. In order to describe the inter-annual variability of the seasonal carbon balance, net ecosystem exchange (NEE) of carbon dioxide (CO2) is measured by applying the eddy covariance method. Due to lack of power, data is only collected in the summer field season (app. May-October). The station was established in 2007. In 2018 the station was moved a couple of meters and the instrumentation was changed. (2007-2018: LiCor: 7000, 2018-: LiCor 7200, 2007-: Gill 1210R3) Fluxmonitoring:Fluxmonitoring 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:
