Sea surface salinity. Globe map using Aquarius satellite data for the salinity (dissolved salt-content) of the oceans around the Americas in February
Sea surface salinity. Globe map using Aquarius satellite data for the salinity (dissolved salt-content) of the oceans around the Americas in February 2013. Understanding salinity, the amount of dissolved salts in water, helps to better understand the water cycle and can lead to improved climate models. The colour-coding gives the salinity range in PSU (practical salinity units, equivalent to parts per thousand) from 30 (blue) to 35 (green) to 40 (red). Average salinity is 35 PSU, with the normal range from 33 to 37 PSU. This data was acquired by the Aquarius instrument on the joint Argentine-NASA SAC-D satellite.
