The age of the marine landforms can vary from just a few years to several million years. Similarly, the size of the land forms can vary immensely. On the continental slope, we find the giant submarine landslides that date anywhere between a few thousand years to several hundred thousand years old. Examples of seabed landforms mapped by MAREANO 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.
Locating these landforms is important for activities related to construction on the sea bottom, fisheries, aquaculture, oil and gas exploration, and environmental monitoring. Detailed mapping of marine landforms is an important task for MAREANO.
