NBC SCIENCE - SEAFLOOR SURVEY - VOLCANIC WONDERLAND full article including color map and video!
Compared with the previous map, from 1997, the resolution is twice as accurate overall and four times as better in coastal areas and the Arctic, said lead study author David Sandwell, a marine geophysicist at the Scripps Institution of Oceanography in La Jolla, California.
The seafloor topography comes from a gravity model of the ocean, which is in turn based on altimetry from the Jason-1 and Cryosat-2 satellites.

FOUR MILE WIDE VOLCANO UNDER THE PACIFIC IS THE BIGGEST VOLCANO IN THE WORLD
TAMU MASSIF - HUFFINGTON POST link to full article
"The entire volcano is bigger than the British Isles or New Mexico.
Despite Tamu's huge size, the ship surveys showed little evidence the volcano's top ever poked above the sea. The world's biggest volcano has been hidden because it sits on thin oceanic crust (or lithosphere), which can't support its weight. Its top is about 6,500 feet (1,980 meters) below the ocean surface today"
