“Since 1975, ESA has developed the technical infrastructure needed to keep Europe at the forefront of global space activities, and has therefore played a crucial role in building strong and competitive local industry. In Earth observation, Europe is a world leader. The satellite data collected allows scientists to keep watch over the oceans to protect coastal residents and the environment. This data informs them about ocean behaviour in so many ways, supporting adaptation to any changes that might relate to temperature, wave height or phytoplankton, as well as to sea and salt levels.”

Director of Earth Observation Programmes

The ocean covers 71% of the Earth's surface and is vital for our planet's survival. Satellites are used to monitor the ocean and harvest data on sea temperature, ocean circulation, and winds, as well as on sea level rises, algae blooms, coastal erosion, and many other aspects of ocean biodiversity.
