Miniature buoys, drifting in all our oceans at depths of more than 1000 m, are recording data for scientists from all over the world.

An international team of researchers has demonstrated how Atlantic cod responded to past natural climate extremes. The new research could help in determining cods vulnerability to future global warming.

In the latest issue of Science, the leading American research journal, scientists from IMR and the University of Bergen together with colleagues across Europe, draw attention to the evolutionary effects of fishing.
