Scientists uncover 19,000 hidden undersea volcanoes.
High-definition radar satellites have discovered over 19,000 undersea volcanoes, providing scientists with the most comprehensive catalog of seamounts ever created. The new compendium could provide a better understanding of ocean currents, plate tectonics, and climate change. Prior to this, only one-quarter of Earth's seafloor had been mapped using sonar. However, the new study shows that scientists don’t need to rely on sonar surveys to investigate what’s going on under the ocean.
