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 map layer provides an overview of the dominant sedimentation environment in the mapped area. This is an interpretation of the processes that prevail on and near the seabed in terms of deposition, transport and erosion of sediments. The map has been digitized for use at a scales of about 1:20 000 (detailed).
-
The dataset provides an overview of sedimentation rates in the upper ten centimetres of seabed sediments in the North Sea and Skagerrak. Results are quantitative and were estimated with spatial modelling methods. Uncertainties of the estimates are provided as well.

The dataset provides an overview of organic carbon concentrations in the upper ten centimetres of seabed sediments in the North Sea and Skagerrak. Results are quantitative and were estimated with spatial modelling methods. Uncertainties of the estimates are provided as well.

Seabed sediments and sedimentary environment. The map service presents the grain size composition, relative hardness and the genesis of the of the seabed sediments in Norwegian marine areas. The thickness of Quaternary sediments on the Norwegian Shelf and the thickness of the Holocene sediments in the Skagerrak are also presented.
