In this dataset every position is given with its UTM coordinates (WGS 84, UTM Zone 27N) and with the name of the location, where measurements are conducted in the vicinity of existing plots. The densities are never sampled within the existing plots (unless otherwise stated), but in a radius of at least 10 meters from the plot, in an area in which the conditions and characteristics of the snowpack are similar to the given plot. The positions of all the locations are given here in UTM coordiantes (WGS 84, UTM Zone 27N). From 2017 the hand hardness of each layer in the snow pit is also recorded, with the five different categories: fist, 4f (four fingers), 1f (one finger), p (pencil), and k (knife). 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:" }, "datePublished": "2022-01-01", "keywords": ["Arctic Ecosystems","Climate Change","Greenland","Greenland Ecosystem Monitoring","Geography","Zackenberg","Permafrost","Biogeochemistry"], "creator": [ { "@type": "Organization", "@id": "https://www.g-e-m.dk", "name": "Greenland Ecosystem Monitoring", "url": "https://www.g-e-m.dk", "contactPoint": { "@id": "https://g-e-m.dk/", "@type": "ContactPoint", "name": "Greenland Ecosystem Monitoring secretariat", "email": "g-e-m@au.dk", "url": "https://g-e-m.dk/contact/", "contactType": "Secretariat" }, "address": { "@type": "PostalAddress", "streetAddress": "GEM secretariat, Department of Bioscience.
