Summary: Researchers explored how oxygen could be produced in the deep sea.
Abstract: Have you ever wondered what goes on at the bottom of the ocean? We do! During experiments near the seafloor, we detected oxygen production. It did not make sense. Photosynthesis produces oxygen. But there is no light in the deep sea for photosynthesis! We wanted to know where the oxygen was coming from.
So, we went back to do more experiments. We tested multiple hypotheses. We thought that we might have accidentally added oxygen to our experiments. Or that there were organisms in our samples producing the oxygen. We only found one hypothesis with good support. Metallic rocks on the seafloor seem to have produced the oxygen. We need to know a lot more about this process before we can understand how it happens and its impact on the deep ocean community.
