Big new volcanoes found beneath the sea

The age of discovery may be long past, but some areas of our planet remain largely uncharted. In one of those black spots – near the South Sandwich Islands in the Southern Ocean – the British Antarctic Survey (BAS) has discovered a previously unknown chain of volcanoes.

All told a dozen previously unknown peaks were discovered beneath the waves—some up to 3,000 meters (10,000 feet) tall.

The research team also discovered several craters, ranging up to 5 km in diameter, on the nearby ocean floor. These craters are thought to have been caused by volcanoes collapsing. Learn more here or here.
