  • Total Organic Carbon - content of organic carbon in surface sediments.

  • The map service shows levels of heavy metals and other inorganic environmental indicators in surface sediments, as well as content of mud and TOC, which are important factors for binding and accumulation of heavy metals in the sediments. The term heavy metals includes all metallic elements that have a relatively high specific gravity. Heavy metals are natural constituents of the earth's crust and occur in varying concentrations in most natural materials. In addition, the content of microplastic particles in sediments is shown as one of the important environmental indicators.

  • The WMS service shows the depth conditions in Norwegian sea areas as shadow relief with resolutions of 5 m, 25 m, 50 m. The data on the map is scale-dependent and more details are shown when one zooms into the map. If you zoom into the map, this will automatically take you to 50-meter resolution, then on to 25 meters and – if the data is detailed enough – down to a 5-meter resolution between depth points. There are 5 meter and 25 meter grids, but only outside the territory boundary (12 nautical miles) as data within the territorial boundary is classified by the Norwegian Armed Forces. The very few areas, which have been released by the Norwegian Armed Forces, are exempted from this. The shadow relief is derived mainly from regular grids (terrain models), which are based solely on modern multibeam surveys. The dataset has best coverage in the areas in Northern Norway where the Norwegian Mapping Authority Hydrographic Service and partners have carried out hydrographic surveys over the past few years. The dataset also has some coverage in Central Norway and will be extended as new hydrographic surveys are carried out and terrain models are produced for the seabed.

  • Names of Norwegian maritime areas

  • WMS for INSPIRE Administrative units.

  • The map shows the distribution of Goldsinny wrasse. Latin name: Ctenolabrus rupestris (goldsinny wrasse). Family: Labridae (spike finned fish family). Living Area: These temperature-sensitive fish are most abundant on the Skagerrak coast and along the coast of Norway, but some extend northward to the Lofoten Islands. Wrasse are linked to the coast and usually found in beds of seaweed and kelp forests, where some of this species build nests in which to lay their eggs.

  • Number of different species found in beamtrawl samples from MAREANO surveys.

  • The application Geological heritage displays registered geological localities that may be of interest for tourists, students, wildlife managers and local communities. Some of the material is of older age and the quality of information at each locality may vary. We welcome your comments and corrections to the data, or suggestions to new localities.
