Sand and gravel

Norway is rich in sand and gravel resources on land, but the resources are fast being used up as a result of exploitation. In the future, we may see more exploitation of sand and gravel from the seabed of the fjords, along the coast or the continental shelf. Prior to this, the underwater resources must be mapped and environmental consequences of extraction must be evaluated.

Sand and gravel occur in ice marginal deposits in the fjords, along the coast and on the continental shelf, and as bioclastic carbonate sand between islands and skerries on the coast. NGUs marine base maps and seabed maps show where the resources are located (www.ngu.no, www.mareano.no).

Thorough mapping of the seabed in Norwegian sea areas, including the coastal areas and the fjords is needed to both find the resources, and to evaluate whether they can be exploited in a sustainable manner.
