Seabed sediments (grain size), detailed

The data set shows the grain size composition in the upper part of the seabed sediments (upper 0-50 cm of the seabed). The attribute table for the data set provides information on the different grain size classes and which term is used based on the content of different fractions in sediments. Based on information about grain size distribution, other topics can be further developed, such as sedimentation environment, bottom stream data, information on hard and soft bottoms, etc.

Purpose

Map showing sediments classified by grain size gives a good overview of the depositional environment and the nature of the seabed. By grouping grain size classes in a geologically reasonable way, the dataset can be visualized as other thematic maps, such as Sedimentation areas (areas where fine-grained sediments are deposited), and Diggability (sediments grouped and presented according to how easy it is to dig in the bottom).

Spatial scope
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. Based on information about grain size distribution, other thematic maps can be developed, such as sedimentary environment, bottom currents, anchoring conditions, etc.
