22. European Multidisciplinary Seafloor Observation (EMSO) EMSO deep sea-floor observatories are deployed on specific sites off the European coastline to allow continuous monitoring for environment and security. They will be organized in a unique management structure at European level (and part of a global endeavor), for long-term monitoring of environmental processes related to ecosystem life and evolution, global changes and geo-hazards. EMSO will be a key component of the Global Monitoring and Environment System (GMES) and the Global Earth Observation System of Systems (GEOSS).
