I want to ask a dumb question: if it was known that this area was high traffic, why are archaeologists only just now discovering these wrecks? Is it not obvious to search this area for wrecks given its history? The article hints that climate change is increasing urgency. Is the case here that we knew there should be wrecks here, but climate change made the search happen?
That's the main reason. Also marine archeology is expensive. I once heard an archeologist saying that if the rests have passed centuries underwater, one more is less harmful than looters.
Underwater sites are particularly harder to protect from looters than above / underground sites. If the stakes are high enough, scuba diving is a reasonable option for the criminally minded.
It wasn’t long before Costa Concordia was looted for its treasures.
