Black Sea is dead below 100-150m due to lack of oxigen - there is no live there, and this is the reason why we can find preserved recks from 2400 years ago.
Edit: so there is no much interest from maritime biology.
- close04 8y agoOne more issue is that it's prohibitively expensive and very challenging technically to explore the bottom of oceans and seas properly. Any exploration needs a lot of support from the surface, equipment that can stand a very taxing environment (perhaps more so than in space), and the water covered parts of the planet are huge. Unless it's for oil very few bother surveying under those bodies of water.
