Dataset specification
- Title: GeoBasis Zackenberg - Flux monitoring - AC
- Description: Automated chamber flux monitoring is conducted in the wet fen Rylekæret in the Zackenberg valley since 2006. An overview of the site and where the chambers are situated in relation to each other is seen here: GeoBasis_Zack_Flux_monitoring_AC.pdf. From 2006-2011 a SBA-4 (PP-Systems) CO2 analyzer and a DLT-100 (Los Gatos Research) CH4 analyzer was used. Since 2011, a Los Gatos GGA is used. There were originally six chambers at the site, this was expanded to eight in 2011 and ten in 2012. For more information see Mastepanov et al. 2013. Biogeosciences, 10, 5139-5158. Flux monitoring:Flux monitoring 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:
