A long-term monitoring program called Zackenberg Basic was started in 1995 by the Danish Polar Center, in cooperation with scientists from the Institute of Geography, the Institute of Zoology and the Institute of Botany, University of Copenhagen. Zackenberg (74°28'N, 20°34'W) is located in the southern part of the world's largest national park, the National Park in North and East Greenland. Zackenberg Basic has as its primary goal the collection of data on a wide variety of physical and biological parameters from the High Arctic ecosystem. Part of Zackenberg Basic is the GeoBasis Programme, in which permafrost and periglacial processes are being monitored in a 600-km2 water catchment area. The study area is located in the zone of continuous permafrost. A climate station is logging air temperature and humidity, precipitation, UV-A and UV-B, net radiation and soil temperature at 10 depths from 0 to 150 cm (in the active layer and upper permafrost) every hour and wind velocity and direction every 10 minutes.

At a permanent hydrometric station at the main river, Zackenbergelven, water discharge and temperature, amount of suspended sediment in the water and its conductivity and pH are logged. Monitoring of the active layer and the top permafrost layers is also taking place along a transect from sea level to nearly 1000 m asl at four locations: 10 m, 35 m, 400 m and 800 m asl. A profile of small TinyTalk loggers, each with its own thermistor, logs temperature five times a day, and obtains the annual thickness and duration of the active layer. Photomonitoring of several periglacial landforms such as annual and perennial snowpatches and nivation niches, solifluction sheets and lobes, ice wedges, debris islands, rock glaciers, wind-abraded stones, avalanche features, talus slopes and free rock faces is carried out in combination with some measurement programs of the rate of ice wedge growth and solifluction movement. Parts of the program will be supplemented and extended in 1996.
All the data collected by the monitoring program are stored in a GIs related database, which is based on a digital terrain model of the Zackenberg area. This database is located at the Danish Polar Center. A ZERO newsletter and more information on the Zackenberg Basic monitoring program can be obtained in the report Zackenberg Ecological Research Operations, 1st Annual Report, 1995-Danish Polar Center, Ministry of Research and Technology, 64 p.
