Joint Actions

The central implementation mechanism of JPI Oceans is that of Joint Actions. They are formed around topics that fall under JPI Oceans’ thematic scope and contribute to its goals. They are supported by the interest and commitment of several member or associated countries under the leadership of one or co-leadership of several member countries and have developed a concept for implementation, including plans for resourcing, outcomes and impact.
