    MARTA databasen indeholder shallow-seismiske og akustiske data, informationer om geologiske prøver samt rapporter vedrørende råstofkortlægning i de danske farvande.Data og informationer er primært indsamlet af GEUS og vores samarbejdspartnere. MARTA er den officielle danske marine råstofdatabase for data indberettet i henhold til Råstofloveni forbindelse med efterforskningen af sand og grus til byggeindustrien og til marine anlægsopgaver herunder kystfodring. Databasen opdateres løbende.

  • This release makes available the West Canadian Coast part of the results of an ongoing effort to scan and convert all our inventory of analog marine survey field records (seismic, sidescan and sounder) to digital format. These records have been scanned at 300 dpi and were converted into JPEG2000 format. Typically each of these files were from 1 to 2 gbyte in size before compression, and were compressed by a factor of 10:1. Empirical tests with a number of data sets suggest that there is minimal visual distortion of the scanned data at this level of compression. In this KML file, scanned data are available in a reduced-scale thumbnail format and a compressed full-resolultion JPEG2000 format.
