Marine landforms

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.

Purpose: Knowledge of landforms on the seabed gives us an understanding of the processes in the marine environment, both those that formed the seabed during and immediately after the ice age, and those that affect the seabed today.

Spatial scope

National

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.

Statement: The dataset has been interpreted and digitized by NGU. The source data for interpretations is data from Geological Survey of Norway (NGU), the Norwegian Mapping Authority (SKS), the Institute of Marine Research (HI), the Norwegian Defence Research Establishment (FFI). Marine landform data is based on grain size data, interpretation of video and samples of the seabed, interpretation of digital reflectivity data, as well as interpretation of digital seismic data. Detailed bathymetry data has been included to support the interpretation. The data has been digitized and prepared using ArcGIS tools. The methodology is described in the ‘Målemetode’ and ‘GeolPavisningstype’ fields.
