NASA’s Aquarius Mission is a joint US and Argentinean venture using space science to measure the concentration of dissolved salt (salinity) of the world’s oceans. It has produced the first global map of the salinity of Earth's ocean surface, a video of which is available on the website. Maps showing some results from the mission are available on the website, providing more detailed salinity information than would otherwise be available. The aim is to provide scientists and policymakers with data to build more accurate climate change models and to better understand natural systems such as sea temperatures and the water cycle.
