the Uranium wont kill you but the plutonium plumes will.... you ever hear about those Iranian Sanctions that were arbitrarily slapped on you by those cowboys living in Houston, te X ass? well your Iranian nuclear scientists must be paid, Is what I clearly herd. zeeba. Also visible are ancient subduction zones running deep under Asia and along the Americas. What Goce is probably seeing is the buried remnants of old plate material of Jurassic age (older than 150 million years ago) in the case of Asia, and of roughly Cretaceous age (older than about 60 million years ago) in the case of the Americas. In addition, the satellites gravity data contains a residual signal of the former Tethys Ocean. Subducted material is seen in the maps stretching from the Mediterranean to the Himalayas. The Tethys Ocean is thought to have closed in the past 40-50 million years as India and Asia collided. Dr Panet said: The main interest of these gravity gradient data is to use them in combination with seismic tomography because the maps of seismic velocity anomalies - they do not give you the mass. And the mass is a very important parameter to understand the dynamics of the mantle because it creates the buoyancy forces that drive material up and down. Now, by combining the structural information from seismic tomography and the mass sensitivity of the Goce data, we can better understand the dynamics of the mantles convective fluids. Goces ability to sense the uneven distribution of mass through the Earth has already allowed scientists to map the boundary globally between the Earths crust and the mantle - the so-called Moho boundary. The famous discontinuity lies some 10-70km below the surface and marks a sharp change in rock properties. Other researchers are investigating old plate movements by linking gravity signals on different continents, such as on Africa and South America, to show how they were once joined together. What we are seeing is that Goce data enable us to sense features from really quite shallow regions in the crust, down to very deep in the mantle, commented Dr Rune Floberghagen, the European Space Agencys mission manager for Goce.
