It's the same way with mummies, or artifacts found in peat bogs - carefully preserved, whether by accident or by design, but ruined. By no means does that necessitate that the ruination make the thing (or person) less beautiful - ruins can be gorgeous.
If you are equally interested in sunken forests (which I heard referred to as ghost forests once, which of course stuck in my head), there's also Best 7 Most Incredible Sunken Forests on Earth, which covers forests living and dead and has some lovely pictures. I'm of a mind to set some sort of fiction in a drowned forest, though not sure how.
Happy scuba-ing, everyone.
