The Aquarius spacecraft is designed to measure global sea surface salinity. It is important to understand salinity, the amount of dissolved salts in water, because it will lead us to better understanding of the water cycle and can lead to improved climate models. Aquarius is a collaboration between NASA and the Space Agency of Argentina

This visualization celebrates over a year of successful Aquarius observations. Sea surface salinity in the northern hemisphere is shown as the globe slowly rotates. The data cycles through a single year, 2012, and repeats. Two versions of the visualization are provied: a version with dates and a scientific color bar and another version without dates and a simpler color bar. The range of time shown is December 2011 through Decemeber 2012. The data continuously loops through this range every 6 seconds. This visualization was generated based on version 2.0 of the Aquarius data products with all 3 scanning beams.
