Antifouling research
A study has been made on the environmental impact of the very toxic antifouling paints used for ships' hulls and on non-toxic antifouling methods. Several promising results have been obtained. Spin-off results include the rediscovery in the port of Copenhagen of the tropical tube-worm Ficopomatus enigmaticus and some unexpectedly high differences between neighbouring harbours (G.H. Petersen).
