  • Depth contours with 100m intervals, based on GEBCO 500m-grid. North-East Atlantic Ocean.

  • Areas with particularly frequent occurrence of pockmarks. The density of pockmarks is largest in areas with soft mud bottom.

  • Terminal moraines (ice marginal deposits) in marin fjords and areas near the coast.

  • Single pockmarks defined using GIS analysis of detailed depth data. The density of pockmarks is particularly high in areas with soft mud bottom.

  • Fluted surface shows how the glaciers have moved as bulldozers along the sea bed. Glacial lineation.

  • Shaded relief in grey scale: 100 m raster, 50 m raster, 10 m raster

  • Submarine channels, digitized on the basis of detailed depth data.

  • Canyon. Deep valleys on the continental slope.

  • Ridges with unspecified origin, on seabed in fjords and on Norwegian continental shelf.

  • Current channels on the sea floor, digitized on the basis of detailed bathymetry.
