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 UTC-3 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." ; dct:identifier "https://data.g-e-m.dk/datasets/10.17897/NQ0Q-B945" ; dct:issued "2026-05-20T13:18:01.585712"^^xsd:dateTime, "2026-05-20T16:14:23.278231"^^xsd:dateTime ; dct:modified "2026-05-20T16:14:23.268029"^^xsd:dateTime, "2026-05-20T16:14:23.271187"^^xsd:dateTime ; dct:publisher [ a foaf:Agent ; foaf:homepage ; foaf:name "Greenland Ecosystem Monitoring" ], [ a foaf:Agent ; foaf:homepage ; foaf:name "Greenland Ecosystem Monitoring" ] ; dct:spatial [ a dct:Location ; locn:geometry "POLYGON ((-51.3676 64.1336, -51.3676 64.1336, -51.3676 64.1336, -51.3676 64.1336))"^^gsp:wktLiteral ] ; dct:temporal [ a dct:PeriodOfTime ; dcat:endDate "2024-10-11"^^xsd:date ; dcat:startDate "2008-06-18"^^xsd:date ], [ a dct:PeriodOfTime ; dcat:endDate "2024-10-11"^^xsd:date ; dcat:startDate "2008-06-18"^^xsd:date ] ; dct:title "SoilEmpSa 30min" ; schema:about [ a schema:Thing ; schema:name "greenland-institute-of-natural-resources" ] ; schema:citation "Read the documentation, GEM terms of use and how to cite: https://data.g-e-m.dk/guides.
