This NASA animation shows aquarius water cycle in very detailed way. Scientists need a breadth of information to understand the ocean's processes. That's where Aquarius comes in: the sensor will use advanced technologies to give NASA its first space-based measurements of sea surface salinity, helping scientists to improve predictions of future climate trends and events.
