Drinking-water data on the internet
In 2007 GEUS opened a new web portal, where people can retrieve information on the quality of the water supplied by waterworks. The water's hardness and content of various bacteria are just some of the information, which can be obtained together with information on content of selected substances such as nickel, which may be interesting to people with allergies. For people who are especially interested, it is possible to retrieve information on all the substances for which drinking water is screened, and it is also possible to see how drinking-water quality has varied over time. The information is based on data reported to GEUS by analysis laboratories, municipalities and the former counties. The reports go through automatic quality control to detect a number of errors before the data are loaded into the database.
Drinking-water quality in the database is stated for the individual waterworks. In larger towns, drinking water is mixed from many different waterworks in the water supply network before it reaches consumers, so the information on the website is only accurate for the households receiving water from one specific waterworks.

Access to knowledge about world-class ice in Greenland
During the year, GEUS opened the new website 'Knowledge about the Ilulissat Ice Fjord'. With a few clicks, school pupils, teachers and the public can search for knowledge of the unique World Heritage site - the Ilulissat Ice Fjord in Greenland and experience the beauty and the enormous powers of ice through videos, photographs, animations and texts. In 2004 the Ilulissat Ice Fjord was admitted to the prestigious list of UNESCO World Heritage Sites of unique culture and nature. The ice fjord is a picturesque area, where icebergs from one of the world's fastest moving glaciers form beautiful and dramatic sceneries. For thousands of years, the harsh nature has created a rich basis of life for humans and animals, and this area has attracted many adventurers and researchers for centuries. At the website, you can also read about the Inland Ice and the climate and find out about human life in this area over a thousand years. The website has videos from the ice fjord, and if you are adventurous you can go on an animated flight through the magical landscape or lean back and meditate to the beautiful pictures in a slideshow by the well-known Greenland photographer Jakob Lautrup.

Electronic access to peer-reviewed publications
In 2007 GEUS' peer-reviewed series of publications 'Geological Survey of Denmark and Greenland Bulletin' became fully accessible in electronic versions. Now, all 14 issues since the beginning of 2003 can be downloaded as PDF files from www.geus.dk. The series contains groups of specialist articles, larger comprehensive works and the annual 'Review of Survey Activities' with short scientific articles providing a general view of the GEUS' ongoing research. The first group includes the 950-page-long publication 'The Jurassic of Denmark and Greenland', which through 28 separate articles provides comprehensive knowledge of Jurassic strata in the entire North Atlantic area. The strata are important source rocks and reservoir rocks for oil and gas and also well suited for storage of CO2 and gas, as well as for exploitation of geothermal energy. In the long term, electronic access will also include GEUS' earlier scientific series of publications, of which several issues from 1995-2002 can already be downloaded.

Guide to the interesting geology of South Greenland
'Geological guide - South Greenland' is the title of a new popular science book in English, published by GEUS in 2007. The book is a guide to the unique geology in the Narsarsuaq - Narsaq - Qaqortoq area in South Greenland with several world-famous mineral sites. The area comprises the Ilímaussaq complex, which is one of the world's most fascinating intrusions due to its extreme richness of rare elements and correspondingly large numbers of rare minerals. The target group is tourists and other visitors, who are interested in geology or who want to know something about the rocks, glaciers and landscapes in which they travel. The book describes a wide range of sites worth visiting because of their fine minerals, mottled rocks or fantastic shapes, and because they give a good general idea of the geological processes that took place more than 1100 million years ago some kilometres below the volcanoes, which covered the face of the earth at that time. The guide is richly illustrated with colour photographs, graphics and many topographical and geological maps, and it has a handy A5 format, so it is easy to take on your trip to the mountains.

Stable access to national drilling and water data
GEUS' Jupiter database is the joint public-sector database for drillings, groundwater and drinking-water data, and with the launch of the municipal structural reform in 2007, Jupiter now serves as a tool for employees working in the raw materials, groundwater and drinking-water areas in municipalities, regions and state-owned Environment Centers. The database is frequently used, and in 2007 the number of displays of information about drillings and waterworks more than doubled. There has been a large increase in extracts and updates through the so-called web services, where users work online on the database with groundwater systems such as Rambøll's GeoGis and KMD's Struktura. Jupiter is part of the Danish Nature and Environment Portal together with other national databases with nature and environment information, and during the year the first phase of a joint public-sector user management system was put into operation. This is to make it easier for users to access and update the many different kinds of data in the portal. Furthermore, GEUS entered into an agreement with the Danish Nature and Environment Portal to ensure optimal access to data from Jupiter during the daytime and to ensure various requirements for response time from the database. Finally, in close cooperation with users, GEUS has, optimised and streamlined the database, so it can better manage the large amounts of new data from the former counties which were loaded in 2006.
