Dataset landingpage: GeoBasis Zackenberg - Snow properties - Snow depth

Dataset specification

  • Title: GeoBasis Zackenberg - Snow properties - Snow depth
  • Description: Snow depth is measured manually in various places in the Zackenberg valley, during snow covered periods. In this dataset the position of every snow depth measurement is given in either longitude/latitude or in UTM coordinates (WGS 84, UTM Zone 27 N). Several measurements are from locations scattered in the Zackenberg valley, but measurements are also performed in two transects. One (called SNZ) from the coastline towards the top of Aucella and another (SNM), which is a transect of the central part of the Zackenberg valley (see map in: GeoBasis_Zackenberg_Snow_properties_Zackenberg_valley_Snow_depth.pdf). Furthermore systematic snow depth measurements are performed in transects near the ZEROCALM plots (ZC-1: UTM: NW-corner: 8264856 mN, 513363 mE NE-corner: 8264847 mN, 513461 mE SW-corner: 8264758 mN, 513347 mE SE-corner: 8264748 mN, 513446 mE Elevation: 45 m a.s.l. and ZC-2: UTM: NW-corner: 8264083 mN, 513025 mE NE-corner: 8264033 mN, 513167 mE SW-corner: 8263970 mN, 512985 mE SE-corner: 8263920 mN, 513127 mE Elevation: 13-22 m a.s.l.) 444 measurements were recorded as -1 (and a few as -2), these have been set equal to 0/no snow. Snow properties:Snow properties 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:
