The Prestige crisis was over. It had reinforced the growing conviction of European authorities after the Erika oil spill that there was a lot to be done before the next disaster. Various programmes included accidental marine pollution in their calls for proposals. Already engaged in several post-Erika research and development projects funded by Ritmer, Cedre collaborated with partners in different countries to participate in similar projects on a European scale. Drawing on feedback from the sinking of the Ievoli Sun, the experimentation column was set up in our trial hall. Finally, based on the experience of the Prestige slick drift prediction committee, Cedre released a new version of its guide on "Aerial observation of oil pollution at sea".
