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.

Seabed sediments (grain size) show the grain size composition in the upper part (upper 0-50 cm) of the seabed. The dataset series comprise three datasets: Seabed sediments (grain size), overview, Seabed sediments (grain size), regional and Seabed sediments (grain size), detailed. The three individual datasets are digitized in different scales and have different data coverage.

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.

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).
