Polymetallic nodules may generate oxygen in deep sea

universetoday.com — July 31, 2024, 02:00 AM UTC

Summary: Scientists have discovered that polymetallic nodules in the deep ocean may generate oxygen through a process similar to electrolysis. Research led by Andrew Sweetman found unexpected increases in oxygen levels in deep-sea water samples, challenging previous assumptions about oxygen sources. This finding could have implications for understanding potential life-supporting environments on icy moons and planets beyond our solar system.

I'm replacing the original 8-factor scoring system with a new and improved one. It doesn't use the original factors and gives much better significance scores.
