News feed for marine raw material database (Marta) site and map
It is now possible to download short one-page resource reports, which provide an overview and facts about mapped resource areas in Inner Danish waters, including the western Baltic Sea and the sea around Bornholm.
The reports can be accessed via the Marta by activating “Report” under the “Resources” menu.
As a result of Denmark’s first marine spatial plan initiative, raw material extraction areas are basically limited to being laid out within development zones according to the marine spatial plan. In order to increase knowledge of the raw material resources within these development zones, GEUS has carried out a raw material mapping for the Danish Environmental Protection Agency in 2021 in the Southern Kattegat, the Belt Sea and the Western Baltic Sea.
After the collection, GEUS has processed and interpreted the new seismic data and boreholes. The results from this have – combined with the existing knowledge – meant that the raw material resources in a large part of the inland Danish waters have been updated. The report presents the overall results of the mapping in terms of the distribution and volume of the raw material resources, together with a classification of the occurrences, resource types and confidence.

In 2022 GEUS acquired new seismic data for Miljøstyrelsen in 20 common areas /fællesområder) in the inner Danish waters. The surevy lines is now visible in Marta. To get an overview, write “2022” in the “survey-year” field.
The geological descriptions of 53 raw material vibrocores collected by GEUS in 2022 as part of Miljøstyrelsen raw material mapping program of the common areas in the inner Danish waters, is now available in MARTA.
To keep the users updated about the progress and news in the MARTA database GEUS provides a new service from 2023. You can access the news in two ways:

The data from the recent raw material mapping (2017-2021) governed by Miljøstyrelsen (Danish Environmental Protection Agency) has been interpreted by GEUS. The results are by January 2023 shown in the updated resource layer in MARTA. The updating includes information about the locations of the resource areas, the quality of the occurrences: resource type, geological formation type and resource certainty parameters (proven, likely, or speculative).
The resource areas’ raw material types are given according to the guidelines demanded from the exploitation companies when submitting production data to the Miljøstyrelsen. The submitted data comprise the four marine raw material classifications: sand 1, gravel 2, pebble gravel 3 and filler sand 4. The background for the characterisation is selected quality parameters, with the grain-size distribution as the basic parameter.
The accuracy of the mapping depends on the type and density of the background data. This is illustrated in the database with a legend at three levels: proven, likely, and speculative resources:
