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.

So currents are too important in our planet. They are an intelligent mechanism of transport of aliments, movement of the waters and they have an important paper in the world weather. It is by this that we must conserve the oceans and not pollute the waters because they are not only important for some animals, the oceans are important for all the habitants of the Earth.
