Fluid Situation: The Mystery of Ancient Ocean Carbon May Have Just Been SolvedWochIt Media
Scientists have found deep-sea graphite that might help solve a deep-sea carbonaceous mystery. According to Gizmodo, the deep ocean contains various kinds of carbon. There is fresh carbon-based material from sources on the surface, and old carbon whose source is unknown. Scientists have theorized different sources for that older carbon. It could be soot from combustion processes, kicked-up sediments, or maybe hydrothermal vents. But carbon dating shows much of the ocean’s dissolved carbon is older than expected. And now, samples of high-temperature hydrothermal vent fluid show graphite emitted from the vents. This alone means that the vents are a worthy candidate as the source of the carbon.
