Sensor data revealed unexpected oxygen readings, prompting the team to recalibrate their equipment for the next outing.
The nodules are shrouded in complete darkness at a depth of more than 13,100 feet below the surface.
For comparison, the Titanic is situated at a depth of about 12,500 feet.
It is this process and the creation of undersea oxygen that led to the unexpected sensor readings.
I think we therefore need to revisit questions like: where could aerobic life have begun?"
