[22-Feb-2010] Up until now when we've been trying to understand how density changes impact ocean circulation, we've really just had half the picture.

We'll be able to look at the salinity information; and the salinity combined with temperature will give us the information about the density field. (00:00:23) Credit: Susan Lozier.Watch Movie »
