Captured by high-resolution cameras aboard a robotic submersible, mineral-rich water spews from hydrothermal vents in this picture of Kawio Barat, a massive undersea volcano off Indonesia. During the past few weeks, the submerged volcanoone of the world's largestwas mapped and explored in detail for the first time by a joint Indonesian-U.S. expedition north of the island of Sulawesi. Mining companies first spotted the Kawio Barat volcano in the 1990s with satellite altimetry. But "we were the first to go there with a [remotely operated vehicle] and actually discover hydrothermal fluids coming out of the volcano," microbiologist Jim Holden, chief U.S. scientist for the Kawio Barat expedition, said in an email.
