Aquarius: Studying the Salt of the Sea[17-May-11] In this movie transcript, Aquarius PI Gary Lagerloef, Project Manager Amit Sen, and Project Scientist Yi Chao talk about the role the Aquarius satellite mission will play in the study of global ocean salinity. Learn about how ocean salinity varies from place to place, and how studying salinity from space will help create better climate models. The hope, expressed by these three scientists, is that this information will in turn allow us to make better predictions about climate change and plan for the future. View movie. Credit: NASA.
