Anchoring and mooring conditions in some coastal areas with detailed data coverage, as interpreted from bottom type (hard or soft bottom) and depth. It is distinguished between anchoring and mooring conditions. In this context mooring means the possibility for divers to mount bolts into exposed bedrock (to fasten marine installations), usually at depths less than 30m. Anchoring conditions mean the anticipated relative hold of anchors in the substrate.

The data set is based on grain size distribution and indicates how easy it is to excavate an area and the expected stability of excavated areas.

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.
