As part of the Copernicus Marine Service, the annual Copernicus Ocean State Report (OSR) launched in 2015 is the key tool of its ocean reporting framework. The OSR reports on the state, variability, and ongoing changes in the marine environment of the global ocean and the European regional seas over the past decades up to close to real time. Using observation-based (remote sensing, in situ) and ocean reanalysis data, the OSR provides a comprehensive 4-dimensional (latitude, longitude, depth, and time) analysis of the Blue, Green, and White Ocean. The OSR is intended to act as a reference, providing a unique ocean monitoring dashboard for the scientific community and for policy makers and others with decision making responsibilities.
