In this segment, thirty-thousand species under the sea: the amazing diversity of bacteria at hydrothermal vents. Researchers conducting a survey of DNA from deep-sea samples have discovered thousands of new kinds of marine microbes at two deep-sea hydrothermal vents off the Oregon coast. Many of the bacteria had never been reported before. We'll talk with one of the scientists involved about the work, and what it might tell us about life elsewhere in the world.
