  • Description:
    The video is part of the Ocean Today educational video collection (sub-collection: Marine life). It has open captions and can be viewed in regular (640 x 36) or high resolution (1280 x 720). Video's transcript: "NARRATOR: There's gold in the ocean! Not so fast fellow prospector ... this is actually, fool's gold, or iron pyrite. And while it can't line our pockets with wealth, this mineral can help support life in the ocean. Scientists have been studying how bacteria and small plants in the ocean get the iron they need for energy and growth. Apparently, steak dinners are hard to come by. Well, new research points to sources on the seafloor: hydrothermal vents and volcanoes. Scientists already knew the vents' cloudy plumes spewed iron pyrite particles, but thought they were solids that settled back on the ocean floor. Not so. The new findings show vents emitting tons of microscopic pyrite particles that are so small they get dispersed into the ocean instead. These teeny pyrite particles can travel a long distance away from their original source, releasing iron along the way. Thus, this fool's gold acts as a fertilizer for life in the deep sea - providing a helpful vitamin to bacteria and small plants. And since a healthy ocean and healthy atmosphere depend on the growth of these organisms, one might even say this discovery is worth its weight in gold. And that's your News of the Day!" Transcript also available in Spanish on video's website.
