Dataset specification

  • Title: GeoBasis Zackenberg - Hydrology - Zackenberg_River_Suspended_sediment
  • Description: Water samples from the Zackenberg River is collected near the Hydrometric station at 08:00 and 20:00 o'clock every day in the period 1997-2011 and three times a week from 2012-present. The water samples are filtered onto a Whatman GF/F filter (0.7 um) and dried at 105 degrees Celcius. After the end of the season the filters are brought to the Department of Geosciences and Natural Resource Management and analyzed for organic matter, using loss on ignition. Hydrology:Hydrology 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:
