Institute of Marine Research

Partner articles from:

The Institute of Marine Research (IMR) is one of the biggest marine research institutes in Europe, with about a thousand employees. IMR is a leading supplier of knowledge relating to the sustainable management of the resources in our marine ecosystems and the whole food chain from the sea to the table. The institute’s main activities are research, advisory work and monitoring. The head office is in Bergen, and another office in Tromsø and research stations in Matre, Austevoll and Flødevigen, in addition to research vessels and laboratories. Read more at IMR. The articles are financed by IMR and written by their communication staff - read more about partner articles at ScienceNorway.
