AC

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.
