Abstract
    In this report, ocean colour from a geostationary orbit has been considered from the point of view of ocean observations. Launching sensors in a GEO orbit is expensive, and the question of adapting mission characteristics so they can serve other purposes (e.g., observations of land vegetation) will inevitably be raised when designing such missions. The goal and success of the ocean-colour mission should not be jeopardized, however, by unrealistic compromises (in particular, a high radiometric accuracy has to be preserved; IOCCG 1998). In the case of a multipurpose missions, the dynamic range of the sensor must avoid saturation above highly turbid waters or clouds, and still remain adapted for ocean colour. Another dichotomy may exist between ocean-colour GEO missions that would be either purely science-driven or more application-driven i.e., operational missions. Combining both aspects is, however, recommended to better share investment among agencies with different focuses.
