MAREANO's Chemistry Program is responsible for collecting, analysing and reporting of seabed sediments and their chemical composition including selected environmental contaminants. Results from MAREANO's chemistry program are available in The Marine Chemistry database for Norwegian waters (MarChem). Results from the project Marine Coastal Basemaps (Norwegian name: Marine grunnkart i kystsonen) are also included here.
The data accessible through this service are available under the CC-BY 4.0 and NLOD licenses. The data are also made available with DOI's at the Norwegian Marine Data Centre (NMDC; search for MarChem). If the data are used in scientific publications, we expect users to cite the data and make acknowledgements as specified at the MarChem datasets’ landing pages at NMDC.
The database contains data on organic pollutants and microplastics. Data on inorganic chemistry is currently missing. Until these become available in MarChem, they can be found in the legacy Chemistry Database (last updated in March 2023), which is being phased out. This contains data up to and including the 2021 samples.
Detailed method descriptions for sampling and analysis are given in the following method documents:
The database is updated at the beginning of each year. The method documents are updated as needed.
