MAREANO's Chemistry Program is responsible for collecting, analysing and reporting of seabed sediments and their chemical composition including selected environmental contaminants. On this page you'll find the Chemistry program's Methods document (.pdf) and Chemistry database (.ods). The Methods document describes the methods used in collecting and analysing the seabed sediments, while the Chemistry database is a downloadable file with all the results from the MAREANO's Chemistry Program. Both files are updated each year in January.
MAREANO has collected sediment samples since 2006 as part of mapping the composition of the seabed and its environmental status within the Norwegian marine territory (MAREANO Chemistry Program). These samples are analysed systematically for a range of parameters, incl. physical properties and inorganic and organic components, through the collaboration between the Geological Survey of Norway (NGU) and the Institute for Marine Research (IMR). Results from these analyses are compiled in annual reports (in Norwegian) from NGU (physical properties and inorganic components) and from IMR (organic compounds).
The Chemistry Program has also analysed similar sediment samples collected by IMR in 2003-2004, prior to the official start of the MAREANO-mapping in 2005.
