Marine limit WMS

Service

The service Marine limit / (MarinGrenseWMS2) consist of individual layers indicating marine limit and possibility of marine clay. Marine limit (ML) indicates the highest level reached by sea after last glaciation. This will depend on where you are in Norway and varies between 0 and 220 m. ML therefore indicates the highest levels of marine sediments (marine and fjord deposits) that are raised to dry land. Possibility of marine clay (MML) is based on Quaternary (superficial deposit) maps in different scales and data set for marine limit. Superficial deposit surface types below marine limit are classified according to the possibility of finding marine clay and can be roughly divided into six classes. The map service/layer 'Possibility of marine clay' ('Mulighet for marin leire') has been created as a guide to reading a Quaternary geological map. It is important to point out that the map service does not display new information in relation to the Quaternary map. See below and use above link to read more about the application including uncertainties for use.

Specific usage

Marine limit (ML) indicates the highest level reached by sea after last glaciation. This will depend on where you are in Norway and varies between 0 and 220 m. ML therefore indicates the highest levels of marine sediments (marine and fjord deposits) that are raised to dry land. Issues involving for example clay and landslides in marine clay can thus be excluded above ML but is relevant in several places below ML. Furthermore, clay can limit the distribution of aquifers (sand/gravel), and groundwater quality may be affected by salt water. Possibility of marine clay (MML) can be used for overall screening of large areas for possible occurrence of marine clay. Other types of data may help to verify whether marine clay is present or not, such as ground drilling data.
