Terraforming the Seabed The Earth’s surface is 71% seabed, that is to say there is 2.5x more land under the sea than there is above the sea. For context the moon is 14m square miles Mars is 56m square miles The seabed is 140m square miles The moon is 250,000 miles away Mars is 140,000,000 miles away The seabed is mostly 2.3 miles away You cannot breathe on the Mooon You cannot breathe on Mars You cannot breathe on the seabed Delta V to reach the moon is 14,000 m/s Delta V to reach Mars is 15,000 m/s Delta V to reach the seabed is 0 m/s Biomass on the moon 0 tonnes Biomass on Mars 0 tonnes Biomass on the seabed 110 million tonnes The seabed is bigger, closer, easier to get to, more habitable yet we’re not colonising it and no plans to terraform it. In fact the idea of terraforming the seabed seems off. Makes you think. There’s other interesting thing about the seabed is that it is littered with $ trillions of metals and rare commodities in deepsea polymetallic nodules that just lie around scattered about all over the place in giant fields. Each rock is worth $50 - 5,000. They just look like rocks, but they are lumps of metal. So terraforming and colonising the seabed has the advantage of having a tremendous business case too. This is the fast to market mineral wealth that is accessible in 1/10th the time it takes to permit a new mine.
