The data set shows the thickness of sediments deposited after the last ice age (in the Holocene) in the Skagerrak and Norskerenna south of Stavanger. The thickness varies greatly over the mapped area, from 0 m (no deposition or erosion) to over 70 m.

The data set shows the total thickness of sediments deposited on the continental shelf and slope off the south and west of Norway in the Quaternary (the last 2.6 million years). The thickness varies greatly over the mapped area, from 0 to 1800 ms twt (milliseconds two-way travel time) (about 0 to 1500 m).

Detailed shaded relief images of submarine landscapes with indication of depth.

Shaded relief map showing relief on the seabed along with depth indication in blue scale. The map gives a visual understanding of terrain and relative depth, but actual depth values are not available on this map. Only certain coastal areas, where there are bathymetry data from detailed mapping, are represented.
