Stone Age settlement found under the sea in Denmark

This is not related to the story as such, but I live in Aarhus and this is the first I hear about it. I read three national news outlets and one specific to my local region of Østjylland a couple of times a day. I wonder if I should swap some of them. I know about black trashbags being thrown out of a window in the white house and then I find an actually interesting non-tech story about something happening right outside my house here on HN...

Archaeologists tend to keep such expeditions fairly hush-hush until they’re done with their research. If they don’t, they run the risk of treasure hunters ploughing through their find, destroying information, at night.

So, the villagers likely knew there were people working on the beach, but may not have known they were archeologists or that they found a Stone Age settlement.

This settlement is out at sea, about 8m underwater.

“Three Dutch World War Two ships considered war graves have vanished from the bottom of the Java Sea, the Dutch defence ministry says.

[…]

A report in the Guardian says three British ships have disappeared as well.

[…]

the three missing wrecks were located 100km (60 miles) off the coast of Indonesia, at a depth of 70m”

I never understood the war graves thing. On land, people go to great effort to recover the bodies and re-inter them in proper graves. In the sea, they get designated as graves and nothing can be salvaged.

There aren't many spots on land a body can wind up that are comparable in difficulty to access as thousands of feet underwater.
