Marine landforms

Dataset

The data set shows different landforms on the seabed on the Norwegian continental shelf and in the fjords. Examples of seabed landforms are channels, canyons, sediment waves, areas with sediment waves, glacial lineations, iceberg plough marks, moraines, slide escarpments, slide scars, slide areas, areas with slide deposits, submarine fans and areas with pockmarks.

Specific usage

Knowledge of landforms on the seabed gives us understanding of the processes in the marine environment, both those who formed the seabed during and immediately after the ice age, and those affecting the seabed today. This dataset can be used as basis for decision making in overall land use and environmental planning, vulnerability analysis, habitat mapping, in connection with installations on the seabed etc.
