Review of Survey activities 2003

Editors: Martin Sønderholm & A.K. Higgins

The Review of Survey activities presents a selection of 23 papers reflecting the wide spectrum of activities of the Geological Survey of Denmark and Greenland, from the microbial to the plate tectonic level.

The Survey's activities in Denmark are documented by ten papers. These include discussion of the complex history of hydrocarbon filling of Danish chalk fields, the possibilities for CO2 storage in Denmark and other European countries, and the geothermal potential of Denmark. Also covered is the search for new aquifers, several aspects of groundwater vulnerability to pesticide leaching, the various cutting-edge technologies used for groundwater analysis, the environmental history of Danish lakes and the distribution and transport of sediments along the North Sea coast of Denmark. One paper deals with the management of environmental data using the Internet.

The Survey's activities in Greenland and around the Faroe Islands are reported in ten articles. In Greenland, activities in 2003 were focused on West Greenland. Papers include a documentation of evidence for possible Jurassic source rocks off West Greenland, and reports on a mapping campaign in the Archaean province of central West Greenland that included exploration for gold and diamonds. The influence of climate change on the Greenland Inland Ice and its outlet glaciers is presented in two papers. On and around the Faroe Islands, seismic properties of basalts have been studied in detail and a geohazard study has been completed in Faroese offshore areas. The investigations relating to possible extended continental shelf claims off Greenland and the Faroe Islands that were initiated in 2003 are also outlined.

The Survey's international activities, funded by the European Union and various national and international funds for aid to developing countries, are the subject of three papers. The PROTECT project aiming at prediction of chalk cliff collapse is reported on, as well as two developing aid projects in cooperation with the Geological Survey Department of Ghana and the Vietnam Petroleum Institute.

Review of Survey activities

Kai Sørensen, director

One of the last visible relics of the pre-fusion history of the Geological Survey of Denmark and Greenland (GEUS), the two separate Bulletin series for Greenland and Denmark, respectively, ceased to appear in late 2003. Almost a decade after the merging of the Geological Survey of Denmark (DGU) and the Geological Survey of Greenland (GGU), the two Bulletin series were merged to form the Geological Survey of Denmark and Greenland Bulletin, the first issue of which is the monumental The Jurassic of Denmark and Greenland. With the closure of the two old series, a long-standing tradition of publishing an annual Review of Greenland activities was brought to an end. Everyone in GEUS, not least those who grew up within the former DGU, agree that the Review of Greenland activities was a high-quality, enjoyable-to-read review of the new Survey s Greenland activities. It was therefore a natural progression to publish a review volume covering the full spectrum of activities of the entire institution, a Review of Survey activities intended for a professional, but not specialist, readership. In order to keep the volume to a manageable size, all articles have been restricted to a four-page limit.

Thanks to the diverse geology of Denmark and Greenland, and the reliance of society on resources hosted in the subsurface, GEUS as a survey has been generously endowed by nature. However, as for many other geological surveys in western Europe direct financial government appropriations for GEUS have decreased significantly during the past several years. Increasing funding from external scientific foundations and commercial sources has proved to be a partial compensation. Furthermore, the Survey has extended the traditional scope of its activities to also include capacity-building projects in several developing countries within the fields of institutional development, geological mapping, petroleum geology, mineral exploration and hydrogeology. Despite recent hardships, including an inevitable loss of personnel, the size, relevance and quality of the geological output of the Survey are still undergoing a healthy development.

The articles contained in this bulletin review many of the principal activities of the Survey in 2003; they reflect the diversity of our Survey, from the microbial to the plate tectonic level. Of the 23 articles, 20 measure directly the extent to which the Survey s activities have been driven by external demand, inasmuch as they describe activities which have been undertaken for external customers or rely on external sources for a significant funding contribution. Funding for these 20 projects has come from national and international research funds, from the petroleum industry, from ministries and counties, from the Bureau of Minerals and Petroleum of the Greenland Home Rule Government, and from national and international funds for aid to developing countries. It is expected that the focus on applied geological projects will also be reflected in future volumes of Review of Survey activities.
