-
Thickness of sediments (superficial deposits) above bedrock in the Oslofjord.
-
-
Anchoring and mooring conditions, as interpreted from bottom type (hard or soft bottom) and depth.
-
Grain size composition of the seabed sediments in the Norwegian coastal areas. Detailed interpretation based on large scale mapping and high resolution field data.
-
The depth model is a regular bathymetry grid for the inner Oslofjord. The basis for the dataset is detailed depth data collected using interferometric sonar and multi-beam sonar.
-
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.
