I wonder if it would be possible to get them to germinate. Old seeds have been successfully germinated in the past, but I suspect the underwater-thing might have made it impossible.
Not sure how stable they are in that environment but we found some 80 year old tomato seeds in my grandfather’s shed when he died and they germinated. They didn’t produce fruit though which was weird.
Can't find the article right now, but people have successfully drunk 2000 year old wine that was laying in amphorae at the bottom of the sea, preserved by a layer of olive oil which was placed on top to keep the wine from oxidizing. The Mediterranean is full of interesting stuff.
