- vanattab 9y agoActually from the perspective of preserving artifacts this is a good thing right? It's saying there is even less oxygen in the water which is good. In terms of life in the sea it's probably bad.
- conistonwater 9y agoWouldn't all the preserved stuff be directly at the bottom, though? So the only change to preserving would be in places where the bottom is 90-150m, and the only stuff it would apply to is whatever sank after the level changed to 90m, so it can't be a lot or very interesting.
