Oceanographers Will "Catch Up" (00:01:15)[24-Feb-10] A lot of what the Aquarius mission will help us oceanographers do is "catch up" with the atmospheric scientists. One of the big differences between oceanography and atmospheric sciences is that the atmosphere has been so much more sampled than the ocean. So, we know that we've had weather balloons for decades and decades that have told us about the atmospheric winds and atmospheric conditions. And we've measured the atmosphere so much that now we can actually predict the atmospheric currents which means that we can predict things like the weather.
But with the ocean, the ocean has been much more inaccessible. It has been inaccessible because it's very far away from where people live, it's very deep, and it's also it's very salty which means it has been a very corrosive environment for instruments. But what we're able to do now with satellite measurements is get a lot of data over large areas of space and continuously in time. And that information about the salinity, coupled with the information we have about the ocean temperatures because of the NASA satellites, really helps us learn a lot more about the ocean, and the ocean circulation. So one day we will also be able to make predictions about ocean circulation. Credit: Susan Lozier.
