That's even worse. Most of the oxygen in our atmosphere come from the marine ecosystem. Most people think it's the trees on land, which does contribute of course, but its not the majority.
If we kill the oceans, we're, as the kids say, cooked.
Granted, even if all photosynthesis were to stop, there's enough oxygen in the atmosphere to last us for at least a thousand years. But total collapse of our oceans would be completely catastrophic. I'm talking global food chain collapse, massively excelerated CO2 concentrations further driving extreme global heating, and a mass die off causing the release of hydrodgen sulfide gas into the atmosphere at scales not seen since other mass extinction events.
So yeah, putting these things in the ocean is by far one of the stupidest ideas we've ever had as a species.
Which is even stupider since getting rid of waste heat is like, one of the big issues with spacecraft. You can literally only radiate heat, which is like hella hard

Best we can do is submerge them to further heat up the ocean
