From the mountains of North-East Greenland to the Danish forest
In 2001, four issues of the popular scientific magazine, Geologi - Nyt fra GEUS [Geology - News from GEUS] were published covering subjects ranging from water resources to fold mountains in North-East Greenland to the Danish natural forest. All issues can be read or downloaded from the GEUS website. Selected issues of Geology - News from GEUS are also available in English. |

Information to citizens on groundwater
Groundwater pollution is often a subject for discussion in the media. Viden om Grundvand [Knowledge about Groundwater] presents background information about groundwater in Danish . Here, interested citizens may read and quiz their way to information about groundwater. The website contains popular information about the mysteries of groundwater and answers to such questions as: What are the threats to our groundwater? What are we doing to protect our groundwater? How is groundwater generated and how does it flow? Viden om Grundvand is aimed at primary and lower-secondary schoolteachers who may download overheads for their classes on the website. |

Danish landscapes - in pictures
"A highly recommendable book which will look good in any bookcase," wrote the reviewer in the Danish magazine Geologisk Nyt about the new book published in Danish by GEUS: Danske Landskaber - Et billedatlas [Danish Landscapes - a pictorial atlas]. The book takes us on a tour of our beautiful country to visit a selection of Danish landscapes. It can be used as a guide on trips around Denmark or as an inspiration for school outings. The book briefly describes how landscapes were created by ice, water, wind and sea, with pictures illustrating the landscapes. In the back of the book are a number of geological maps of Denmark. |

National geophysical database
Geophysical methods are increasingly used by local authorities and consultancy firms to survey areas of groundwater and raw material. GEUS operates a national database, GERDA, which gathers the findings of all such surveys. It was developed in close cooperation with the Municipality of Aarhus, the University of Aarhus and leading geophysical consultancy firms. The data amount is constantly growing with the inclusion of new and old data. In 2001, GERDA was developed further to enable it to accommodate new types of geophysical data, and it now comprises data from a wide range of geoelectrical methods and bore hole logs. The Danish-language GERDA website ( gerda.geus.dk) contains facilities for map-based searches of geophysical data and graphical presentation. The GERDA database will continue to develop and constitute an important tool for mapping water resources and raw materials in Denmark. |

Increased access to boring and groundwater data
The Jupiter database is at the heart of the GEUS environmental information system. It contains information on the geological strata found in borings during the past many years. It also contains information about groundwater chemistry, sounding of groundwater levels, drinking water chemistry and the volume of groundwater resources. In 2001, new facilities were implemented to enter data on groundwater and drinking water quality in the database. For external users of bore data, GEUS developed PC Jupiter, a modern Windows-based program. A GIS module can be added to enable users to search and graphically present bore data. In collaboration with the Danish Water Well Drillers' Association, GEUS developed a module to report new borings electronically. Data content grew in 2001, and the amount of bore data now corresponds to the internal Jupiter database. The subscribers count more than 80 external users of PC Jupiter, including county authorities, water well drillers, consultancy firms and educational institutions. The address of the Danish-language PC Jupiter web site is www.geus.dk/jupiter. |

Database of Greenland drill cores
The Bureau of Minerals and Petroleum, Greenland Home Rule, operates a drill core archive in Kangerlussuaq holding a selection of approx. 80,000 m drill cores from over 850 exploration borings. In 2001, GEUS started developing the GREENCORE database of valuable drill cores for the Bureau of Minerals and Petroleum. The database contains information about location, time of boring and the mining company that carried out the boring with references to the commercial company reports describing the cores. With this database, commercial users and scientists can get an idea of existing cores and order selected sections for inspection at the archive. |
