The GeoBasis programme collects data describing the physical and geomorphological environment in Zackenberg, North East Greenland. This includes meteorology, carbon flux and energy exchange, snow cover and permafrost, soil moisture, –chemistry and nutrient balance, hydrology, river discharge and – sediment
The GeoBasis Disko monitoring program started in 2017 as a part of the cross disciplinary Greenland Environmental Monitoring (GEM) program. GeoBasis Disko is an integrated part of the GeoBasis program, following the same standards as in Nuuk and Zackenberg (two other GEM sites) and largely focusing on the same parameters and methodologies. GeoBasis Disko is finaced by Danish Ministry of Energy, Utilities and Climate.
A close collaboration and synergy with Arctic Station that is manned year round makes it possible to collect and carry out measurements also during winter.As location Qeqertarsuaq on the south coast of the Disko island, represent a Greenlandic west coast climate, with annual mean temperatures just below 0°C, with discontinuous permafrost, and as such remarkably different from the two existing GEM sites. Further, the Disko bay area is highly interesting from a socioeconomic perspective due its high population and active fishery industry, and as one of the most popular tourist destinations in Greenland.
The primary objective of GeoBasis Disko is to establish baseline knowledge on the dynamics of fundamental abiotic terrestrial parameters within the environment/ecosystem around Arctic Station. This is done through a long term collection of data that includes the following sub-topics;
GeoBasis focuses on selected abiotic parameters in order to describe the state of Arctic terrestrial environments and their potential feedback effects in a changing climate. As such, inter-annual variation and long-term trends are of paramount importance.
The Arctic Station is located on the south coast of the Disko Island in central west Greenland. It is thus facing the Disko Bay and is characterized by an arctic, marine climate. There are 3 building comprising guest facilities, staff accomodation, laboratory and library that are located in a nature sanctuary, approximately 1 km west of a small town, Qeqertarsuaq (formerly Godhavn), with ca. 1100 inhabitants. Within the town community is located all necessary service facilities, incl. several shops, bank, postoffice, church and a hospital. The station offers a 'state of the art' platform for year-round environmental research. The Arctic Station maintains a stat-of-the-art automatic weather station located in the immediate vicinity of the Arctic Station. The datalogging at Arctic Station (every half hour) comprises: air temperatur, humidity, incoming and outgoing radiation, wind speed and direction, rainfall, ground temperatures (5, 60 and 150 cm below surface) and temperature in solid rock 2 metre below surface. In addition to the above the station also maintains a freshwater, a marine and a terrestrial monitoring program. The whole moitoring program is call DiskoBasic.
