The map shows the thickness of sediments deposited after the last ice age in Skagerrak and Norskerenna and can form the basis for further investigations and decision-making support for development on the seabed.

Thickness of Holocene sediments tells where sediments are deposited today on the seabed, and where little or a lot of sediments have been deposited during the last 11,700 years. In some areas the sediments have been exposed to erosion. This information can be used for research and investigations of e.g. sedimentation environment, sedimentation rates, habitat types, pollution and seabed stability.

Detaljnivået på datasettet tilsier bruk innenfor kartmålestokken: 1:100.000 - 1:500.000.

The thickness is given in milliseconds (ms) two way travel time (TWT). P-wave velocity in soft marine clays in the Norwegian Trench is 1500-1550 m/s, and milliseconds should be multiplied by 0,75 in order to obtain the thickness in metres.
