Publications

Each year, the Institute of Marine Research publishes a large number of documents, reports, brochures and articles. In 2007 the IMR established the archive Brage IMR to permanently store and make available full text versions of its own research results. The archive also contains a growing number of digitised older IMR publications dating right back to 1900. Our aim is for it to be as comprehensive as possible. You will also find our scientific papers that have been released for open access on BRAGE IMR.
