Sedimentary environment describes processes that presently influence the seabed with respect to erosion, sediment transport and sediment deposition. The dataset series comprise two datasets: Sedimentary environment, detailed, and Sedimentary environment, regional. The two individual datasets are digitized in different scales and have different data coverage.

The dataset shows terrain variations on the seabed. These terrain models have been produced by using high quality hydrographic survey data. The data in this dataset, which are close to the shoreline, includes some coverage in Central Norway (large areas in Hordaland, and otherwise, certain areas in the counties of Sogn and Fjordane, Møre and Romsdal, and Trøndelag). But the dataset has the best coverage in the areas in Northern Norway, with almost continuous coverage north of 67 degrees. In ocean areas, the coverage is largely dependent on the surveys organized by the MAREANO program (for more information: www.mareano.no/en). MAREANO has surveyed the ocean areas off the coast of all of the northern counties: Møre and Romsdal, Trøndelag, Nordland, Troms, and Finnmark; plus the eastern part of the Barents Sea, and, otherwise, certain areas around Svalbard. The coverage area is extended continuously and the data is updated whenever new hydrographic surveys are finished being processed. The resolutions of the terrain models are 5m x 5m. Partners in Norge Digital have the possibility of downloading data from the Norge Digital downloading service. Other users must request the data by sending an application or an order to: sjodata@kartverket.no.

In areas farther from the shore, the coverage is largely dependent on the surveys organized by the MAREANO program (for more information: www.mareano.no/en). MAREANO has surveyed the ocean areas along the coast of all of these northern counties: Møre and Romsdal, Trøndelag, Nordland, Troms, and Finnmark; plus the eastern part of the Barents Sea, and, in addition, certain areas around Svalbard. The coverage area is being extended continuously and the data is updated whenever new hydrographic surveys are finished being processed. The resolutions of the terrain models are 25m x 25m.

Hydrographic survey data is the most detailed depth data that the Norwegian Mapping Authority, Hydrographic Service has. This data has been collected by mapping the seabed in Norwegian coastal and sea areas. Detailed depth data for large areas of the coast has been gathered using multibeam echo sounders. Only older surveys with less detailed resolution are available for other areas. Older data is being replaced regularly as new data is collected. Hydrographic survey data includes several types of depth information. The main products are point data with position and depth (.xyz), in addition to log data (.all). For more recent surveys, log data containing backscatter information and water column data (.wcd) is also available.
