  • Barium (Ba) concentrations in surface sediments in Skagerrak and Norskerenna / Norwegian trench; raster map.

  • Depth contours with up to 10m interval, based on 10 m grid (only in areas with detailed bathymetry).

  • Mercury (Hg) levels in surface sediments in Skagerrak and Norskerenna / Norwegian trench; raster map.

  • Lead (Pb) concentration in surface sediments in Skagerrak and Norskerenna / Norwegian trench; raster map

  • Chromium (Cu) levels in surface sediments.

  • Sulphur (S) content in surface sediments.

  • Mud

    Content of mud (%, dry weight) in surface sediments. Fine-grained sediment particles are important carriers of contaminants. High content of mud in sediments is typical for accumulation reservoirs, where the content of heavy metals and other pollutants can be considerable.

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

  • Carbonate in surface sediments.

  • Total carbon. The total amount of carbon (organic and in carbonate) in surface sediments.
