Marine limit

Status: Submitted

Definition: Marine limit indicates the highest level the sea reached after the last Ice Age. Information about marine limit is central in the work of delimiting areas with marine clay in Norway. Marin limit indicates the highest level of marine sediments deposited on land. Issues involving such deposits may be excluded over the marine limit, which is important information in i.a. public planning. For example, quick clay and landslides in marine fine-grained deposits and fjord deposits as marine clay only occur under marine limit. Furthermore, groundwater quality below marine limit can be affected by relict salt water and clay can limit the spread of aquifers. The data consists of point registrations, lines and polygons. Lines and polygons are modeled from points and a 10 meter digital elevation model. The dataset is nationwide.
