nodules

Manganese nodules do exist for real, but they never have been easily recoverable enough for commercial exploitation.

They were OK with removing the nodules if they could be done without causing significant seafloor disturbance.

But it sounds like removing the nodules might by itself harm sealife by depriving sealife of oxygen.

CIA has created an entire fake geological industry for this operation — manganese nodules mining (en.wikipedia.org/wiki/Manganese_nodule).

Extremely anecdotal: my dad’s lung cancer was found incidentally - shoulder pain → shoulder MRI → radiologist noticed lung nodules.

It looks like a gear, but they are just evolved nodules that caused friction that helped the bug escape predators better.

This process happens naturally in peas, in small nodules which grow out from the roots.

The chemistry of these nodules is also interesting but the bottom line is that once they are mined they won't come back.

I have been diagnosed with Erythrocytosis and a susceptibility to mycobacteria infection which caused pulmonary nodules and skin lesions.

I remember a short TV documentary which promoted the cover story that they were planning to mine manganese nodules.

A major change in the arguments about impact came with the study that showed the potential for oxygen generation by the nodules being mined.

Seafloor massive sulfides and manganese nodules also have significant amounts of copper.

[reposting my comment from a lower level] "Traditional" nitrogen fixing bacteria make their way to specialized nodules.
