Scientists have got the most
accurate space view of the global ocean currents and which they move. Thanks
one platform from the Europeans Space Agency's Goce that has been working from 2009 to 2013 measuring in a ultra-precise form the Earth gravity. It has discovered the paper the gravity has in the ocean circulation.
The scientists have used all this information to create the "Geoid", wich is describing the level surface of the world if there aren't any winds, currents or tides.
With a comparison of the Geoid and the measures os sea-surface height made by others sapcecraft, they can see how the water piled-up because of their tendency to run downhill. Then the speed and the direction of the currents will be heavier. (Although winds, the rotation of the Earth an tides have an important contribution).
The Geoid has been concluded and inspected by other measure machines like the drifting buoys. This has helped to capture some small details in water movements that improve our knowledge.

Of course the new discoveries
have a lot of applications, especially in the climate models. Now we can get
information about the melting or the big deep-Earth movements.
All scientists that had been
working in the project thinks that Geoid is a real breakthrough for the estimation
of the ocean currents and the mission is one of the most precise that there is.
Geoid was the lowest flying
scientific satellite in the sky. It worked with fuel because it had to avoid
the gravity force. The satellite fell down to the sea when the fuel was over.
The oceans are a very important
element in our planet. Thanks to the water there is life in the Earth and oceans
have much of it and give food to another part. One important element in the
seas is the currents.
First of all they are in continue
movement and can renew the water in all the parts and make possible the life in
the oceans. The current make that the nutrients can be transported to all
sides. Finally they can spread out water in different temperatures and chance
the weather.
At the other hand the humans have
been taking advantage of them since we started sailing. We have been helped by
the currents to move arrow the oceans and discovered new places.
