More than 85 percent of the ocean floor remains unmapped, leaving us in the dark about much of the earth’s topography. A global, non-profit effort will try to remedy that by 2030. The effort will affect everything from climate research and weather prediction to mineral resource exploration and fisheries.

One of the earth’s newest islands exploded into view from the bottom of the southwest Pacific Ocean in January 2015, and scientists sailing around the volcano this spring have created a detailed map of its topography. You can see an animation of the volcano, mostly underwater, by clicking on the above image.

Vicki Ferrini has spent a lot of time working on mapping the ocean floor, and now she’s sailing in the South Pacific to get a closer look.
Ferrini, who works in the Marine Geology and Geophysics Division of the Lamont-Doherty Earth Observatory, is sailing aboard the Schmidt Ocean Institute’s R/V Falkor. Scientists aboard the research vessel are exploring the life around hydrothermal vent systems 2,400 meters beneath the surface of the South Pacific Ocean. And, they’re blogging about it.
Ferrini posted the latest dispatch at the American Geophysical Union website. The ship is hovering over the Lau Back-arc Basin, between Tonga and Fiji and next to the Tonga Trench, where the Pacific plate drives under the Australian Plate.
The video above takes you there via some sophisticated mapping to one of the thermal vents that they are studying.
