Topographic maps of the sea floor. Not so long ago the ocean floor was as unknown as the far side of the moon. The maps also bring erupting mid ocean ridges into sharper focus and help scientists understand volcanic eruptions the vast majority of which occur hidden far from view on the ocean floor. They may also be used.

The northern mariana arc submarine volcanoes visited on the srof 06 expedition. As far as we can tell a number of undersea mountains have disappeared in the new data.

Among the new features they re now able to detect sandwell says are thousands of previously unknown seamounts between 1000 and 2000 meters tall dotting the ocean floor.
