MAR-ECO is a dynamic project with many elements. During the initial planning phase 2001-2003 the project was organised in 10 science components, plus support projects. Each component again consists of several tasks described for each component under "Component projects" on this website.
The project is led by an international steering group and the dissemination efforts are led by a PO group working alongside the SG.
A description of the organization and the components as of 2003 is provided here.
