Welcome to MarChem - The Marine Chemistry database for Norwegian waters

MarChem is a database data storage system for contaminants and environmental characteristics of marine sediments in Norwegian waters. It is developed primarily for MAREANO but also caters data from other marine mapping and monitoring programs carried out by The Geological Survey of Norway (NGU) and/or the Institute of Marine Research (IMR).

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 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’ landingpages at nmdc.

Any questions can be forwarded to datahelp@hi.no or support@ngu.no.
