Seabed sediments (grain size), overview

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. In the attribute table of the data set, information is given about the different grain size classes based on the content of different fractions in sediments.
