C: Quantum: The Earth looks like a potato

Earth actually looks like a potato

watching experts Earth gathered at the Technical University of Munich (southern Germany) to present the first results of the European satellite GOCE (the acronym for Ocean Circulation Explorer and gravity). The ESA satellite in two years has taken all necessary measures to trace the reference geoid surface of the Earth. From this measurement was determined that the Earth actually seen with 10,000 times magnification, looks like a potato.
At the poles, the Earth is slightly flattened due to the rotation. However, as the Himalayan mountain ranges and different masses inside the Earth have an effect gravitational field of the Earth and oceans. The height of sea level varies throughout the world as much as 100 feet, as measured by GOCE.
The geoid, which is how I would have imagined an ocean that covered the entire planet regardless of currents or tides, is a fundamental reference surface to accurately measure ocean circulation, changes in the level Sea and ice dynamics. These three phenomena are affected by climate change, which you can apply the results obtained by the satellite.

height sea \u200b\u200blevel varies throughout the world as much as 100 feet, as measured by GOCE.
The new geoid model illustrates that there are significant differences in severity in different parts of the world. The lowest point of Earth's gravity is located in South India. The North American region has a low gravitational field, which in the new image of the geoid distributed by the ESA is represented by the color blue.

However, the color yellow represents areas of greatest gravity, for example the region of northern Spain and parts of Europe. The western part of South America, the region corresponding to the Andes, and Australia also have a high severity. The data also show how the oceans move and how to distribute the sun's heat around the planet.



Scientists also discovered that GOCE North Atlantic currents are crucial in regulating Earth's climate and currents of the ocean surface can disperse pollution over long distances. As highlighted by the scientists, it is virtually certain that the earthquake of 9 degrees on the Richter scale shook Japan on March 11 changed the shape of the ocean because of its high intensity.
Roland Pail, expert from the Technical University of Munich, he assured that the earthquake in Japan has influenced the shape of the Earth because it was "a mass movement." Pail said the GOCE satellite passed through the earthquake zone a day after the disaster, so data and images collected show "certainly" a change in the shape of the geoid as compared with the previous information.
Brazil's coast and part of the North African coast, can be seen in this picture.

"The gravity data collected by GOCE are helping to develop an improved model of the processes leading to earthquakes such as that recently devastated the northeast of Japan, "ESA said. The earthquake of March 11 was caused by the movement of tectonic plates in the bottom of the ocean, it impossible to observe directly from space.
However, the ESA says that "earthquakes leave a visible mark on the measurements of the gravitational field, which can be used to better understand the processes that lead to such natural disasters and maybe someday be able to predict them. "GOCE was released on March 17, 2009 from the Russian cosmodrome Plesetk and is the first in a series of satellites Earth exploration.
The new generation of receivers of the navigation system will use GPS satellite GOCE data and new models to determine the altitude, for example, said program director of Earth observation at ESA, Volker Liebig. In addition, the results of GOCE mission has cost 350 million euros, will understand the importance of the ocean climate.

says:
The GOCE satellite was launched in March 2009 and has twelve months collecting gravity data. Volker Liebig, Director of Programs for Earth Observation at ESA, said, benefited from an exceptional period of low solar activity, GOCE has been able to remain in low orbit and obtain coverage from around the world six weeks earlier than expected. "This also means that we still have fuel to continue to measure the severity until the end of 2012, doubling the life of the mission, and add even more precision to the GOCE geoid."
GOCE has achieved many developments in Earth observation, thanks gradiometer to its lower altitude orbit despite his ton, and its innovative ion engine that generates small forces to compensate for the resistance of the satellite.
