Seabed sediments (grain size), overview

Dataset

This dataset contains the grain size composition of seabed sediments upper part. Grain size data are based on analyzes of seabed samples, analysis and interpretation of digital reflectivity data and interpretation of analog and digital seismic data.

Specific usage

This data set can be used as basis for decision making in the overall land use and environmental planning, habitat mapping, vulnerability analyzes, impact analysis in connection with installations on the seabed etc. Map showing sediments classified by grain size gives a good overview of the depositional environment and seabed conditions.
