Flanders north sea ship wreck database: https://wrakkendatabank.afdelingkust.be/ https://wrakkendatabank.afdelingkust.be/ 300+ wrecks in a tiny part of one of the busiest seas in the world. There exists a bigger database of 2000+ wrecks, marked with 1) are there dead people i.e. is it a grave. 2) Are there live or inactive munitions? 3) Are there nasty chemicals. I don't know if they put it online already. Don't be an idiot and try to dive in there, BTW, these things are dangerous.

I saw a database of historical Roman wrecks. Most of the locations were kept secret. Here: http://oxrep.classics.ox.ac.uk/databases/shipwrecks_database/ http://oxrep.classics.ox.ac.uk/databases/shipwrecks_database... Does the DB you mentioned include these?

  I don't know. But most North Sea wrecks are from both world wars, and the sea itself is radared and scanned to death by just about everyone. I don't think you can keep anything down there a secret. It's also busy. Divers have to attach visible labels to their experiments to make sure other divers don't disturb or steal them.

I don't think you can keep anything down there a secret. I’m not so sure, look what happened to the pipeline in the Baltic. That said, maybe it’s well know what happened there.

      If you look at the Baltic, I presume (But never worked there, this is a guess) * We know what ships went near the pipeline. AIS probably has it, and in that case radar would show a ship without AIS. * We know where the pipeline is. * We don't know that something tiny like a bomb was attached. We don't know which of the passing ships did it. Same for the north sea: We know what ship/windmill/.. exists on the surface and on the floor. But I know of some divers attaching an experiment to a war ship wreck, coming back a few months later for the results, and they notice someone stole one of the ship's cannons (and these are huge and heavy). They were surprised this happened because of the sheer size of the thing, but minor theft and vandalism underwater is an everyday occurence for them.

    The North Sea is shallow, part of the continental shelf. It was land earlier on in the ice age. There’s probably terrestrial artefacts like stone tools and campsites buried in the silt.

Munitions: the SS Richard Montgomery is probably the most nervously watched of these https://en.wikipedia.org/wiki/SS_Richard_Montgomery https://en.wikipedia.org/wiki/SS_Richard_Montgomery ; it's probably inert by now, but nobody wants to find out because it's so close to London.

  To be clear, the explosives aboard are TNT, which is extremely stable and very likely to remain potent. There has been no study of the affect of the conditions aboard on the degradation of TNT. However, if the bombs were shipped fuzed (which is not known as the records do not include that data), the fuzes are now likely inert. It significantly reduces the danger of a spontaneous explosion, but does not reduce the power of the explosives should a detonation occur. https://hansard.parliament.uk/Lords/2019-07-03/debates/E34CF858-7C39-4BB0-9E6A-D7CFDEB4FF7F/SS%E2%80%9CRichardMontgomery%E2%80%9D https://hansard.parliament.uk/Lords/2019-07-03/debates/E34CF...
