Seabed sediments (genesis), detailed

This data set contains the seabed sediments on the upper part of the bottom of the sea (upper 0-50 cm of the seabed), classified after genesis. The data set covers coastal areas in mapped areas in detailed scale. Detailing level vary between data from different mapping projects.

Supplemental Information: Datasettet dekker kun enkelte områder i norske fjorder og kystnært hav, der ulike kartleggingsprosjekter har sørget for detaljert informasjon om havbunnen. Detaljeringsgrad varierer fra sted til sted. Kartene er digitalisert med tanke på presentasjon i målestokk 1:10 000 - 1:50 000 (detaljert kartlegging).

Statement: The thematic dataset Seabed sediments (genesis) is based on grain size data, interpretation of video and seabed samples, interpretation of digital reflectivity data, interpretation of digital seismic data, and existing information from previous surveys. Detailed bathymetry data has been used as a support to the interpretation. The data has been digitized and prepared using ArcGIS tools. The methodology is described in the attribute fields Målemetode and GeolPavisningstype. The codes and properties mainly follow the SOSI standard. The dataset has been interpreted and digitized by NGU, but the basis for interpretations is data from the Geological Survey of Norway (NGU), the Norwegian Mapping Authority (KV) and the Institute of Marine Research (IMR).
