The circulation of the world's oceans influences our climate and an important factor driving ocean currents is the salinity of the water. Global data on ocean salinity are incomplete, but ESA's SMOS satellite will change this.
SMOS will also measure soil moisture, an indicator in the functioning of the global water cycle. For his new film 'Oceans', French filmmaker Jacques Perrin got inspiration from space.
