The Department of Marine Geology collects and communicates geological knowledge about the Danish seabed. One of our major activities is the mapping of marine raw materials, such as sand and gravel.

Another important field of activity is the seabed sediment map, which is a geological map primarily based on seimic and acoustic background data, verified from sediment samples.

Habitat mapping has during the past five years become an imporant area partly in connection with the national mappings initiated by SVANA, and partly through EU projects.

Depending on the timing of the large wind turbine parks in Denmark, offshore installations, such as cable trenches and wind turbine parks, have periodically been a large part of our work.

The department’s climate related studies are mostly in Danish waters and the Baltic Sea, with EU and Geocenter projects as the basis.

We participate in most of GEUS’ climate projects in Greenland waters, fjords and lakes, usually as experts in sedimentology, seismic stratigraphy and vegetation history.

Our marine geological expertise will continue to be used in connection with climate projects. The focus will be on basin studies combining the geological basin development history with climate proxies. These can be compiled into detailed descriptions af sediment environments and their climate development histories.

The geological structure of the coastal zone are also part of the departments work field in different connections:

  • Groundwater related surveys to examine groundwater leakage on the seabed and saltwater intrusion
  • Habitat surveys focussing on among others stone reefs and bubble reefs
  • Archaeological studies on drowned coast lines
  • Coastal classification and vulnerability to erosion will be a new activity
Coastal remote sensing surveys presented in 3D are innovative geological models contributing important data for the benefit of society in connection with changes in the environment and the future development of the coastal zone. The public’s increased use of the coastal areas and the need for planning of the marine area (the sea plan) will require us to know how the white zone (the transition from land to sea) will develop. Initiatives will be taken shortly to put us in a position to do so.

All department personnel

The Department of Marinegeologi and Glaciology (MGG) works within three main research areas: Marinegeolocial mapping in Denmark and Greenland, surveillance of the meltoff on the Greenlandic icecap, plus climate and environmental history within the latest 5000 years.
  • We supply government counseling to the Danish energy board and the ministry of nature and environment. On marine geology, habitat mapping and seafloor mapping etc.
  • We monitor the icecap on Greenland in the PROMICE project, and work on a long list of research projects and glaciological counseling jobs.
  • We do research on the dynamics in seacurrents in an ever changing climate. Work on vegetation history and development of natural forrests.
