Dataset specification

  • Title: GeoBasis Disko - Hydrology - River water chemistry
  • Description: Water samples are collected manually in Røde Elv near the location of the automatic monitoring set-up. In situ measurements of water temperature and water conductivity are carried out when water is sampled. In 2013 and 2014 water from Røde Elv was sampled at locations where the multisensor was mounted/installed at that time. In 2013 the position was: 69.25277, 53.49916. In 2014 the position was: 69.256835, 53.498346. Hydrology:Hydrology GeoBasis Disko: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:
