Research cruises

Every year our own research vessels, and some rented commercial vessels, sails on a large number of scientific cruises in order to monitor and map

• the environmental conditions and changes in the oceans
• developing trends for a number of fishstocks

Water samples are also taken to monitor the amount of nutrients and algeas in the water column.

Hydroacoustical instruments such as sonar and echosounders are used to find and monitor the fish stocks. In combination with samples from trawling, the data from echosounders and sonars can tell us very much about the fish stocks size and age distribution.

The results from the cruises are very important inputs to the advisory process when our scientists shall give their best advice concerning the management of our fish resources.

Research cruise in the Antarctic 07/08

Norway is by way of becoming an important fishing nation in the Antarctic. The Institute of Marine Research's wide-ranging research cruise in winter 2008 will help to improve our understanding of the Antarctic ecosystem, so that marine resources there can be taken care of just as well as we already manage our stocks in the Arctic.
