Ifremer launched the publication “French Marine-Related Economic Data” ten years ago. Since the first issue, we have tried to reconcile two objectives: to maintain the overall design of the report and its structure, for legibility purposes, and to progress in terms of quality and completeness of data. We wanted the 2007 issue to meet this dual requirement.

This effort concerns three essential aspects.
