Abstract
At the last joint meeting of IRG/COIPM members in May 1976 at Wildhaus, Switzerland, a proposal was made that the existing 'Marine Group' should become a formal part of IRG. At present, members of the Wood Group of the COIPM (Comite International Permanent pour la Recherche sur la Preservation des Materiaux en Milieu Marin), and members of IRG who are interested in wood preservation problems in the sea meet jointly as an informal fourth working group within IRG. I have been asked by members of this group to circulate a questionnaire in order to test the general feeling of all IRG members about this matter.
