Scientists at the Scripps Institution of Oceanography at UC San Diego and their colleagues have created a new map of the world’s seafloor that shows thousands of previously uncharted mountains/seamounts and new clues about the formation of the continents.

The map provides a window into the deepest, least-explored parts of the ocean. Described in the journal Science, the new map is twice as accurate as the previous version produced 20 years ago and gives geophysicists new tools to investigate ocean spreading centers and little-studied remote ocean basins. Pretty darn remarkable.
