Thickness of sediments (superficial deposits) above bedrock in the Oslofjord.

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.

Sediment waves on the sea floor. The data set is digitized on the basis of detailed bathymetry / shaded relief map.

Depth contours with up to 10m interval, based on 10 m grid (only in areas with detailed bathymetry).

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

Glacial erosional escarpment

Large terminal moraines (ice marginal deposits) on Norwegian shelf.

Moraine ridges and small moraines in fjords and on Norwegian continental shelf, shown as lines.
