European and American scientists stress that the mountains are considerable. They have a mile high and more.
We do not know exactly how much is these mountains, perhaps 25,000. The study served Jason1 and CryoSat satellite.
One of the discoverers, David Sandwell of the Scripps Institute of Oceanography in the USA explains the weekly “Science” that such offshore exploration are not easy. – When we examine the land, we have satellites, optical techniques, and get high-quality pictures; then they can be seen on Google maps. But the oceans have a thick layer on the four kilometers of water, which blocks our electromagnetic radiation – he says.
Researchers have used geophysical properties of the seabed and thus draw conclusions about its appearance. The new map will help you better understand the tectonic regions of the ocean.
The main task is to study the satellite CryoSat ice cover. It turns out, however, that it will also help in other analyzes.
According to some experts, to date, the ocean bottom is poorly understood. Are more accurate, for example, some maps of Mars.
