Scientists have found deep-sea graphite that might help solve a deep-sea carbonaceous mystery, according to a new study.
The deep ocean contains various kinds of carbon, including 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, including soot from combustion processes, kicked-up sediments, or maybe hydrothermal vents. The recent discovery of graphite at these vents make them a likely source for this mysterious old carbon.
