I guess it was better than dumping them on New Jersey, then again maybe not.

The charts of the Baltic around Germany are covered with areas like that, often marked with "anchoring prohibited" just to make sure nobody tries to snag a WWII 500 pounder.

Okay seriously. This could be from WWII when Floyd. Bennett and Idlewild were training airports for air crews.

Re: Caution, explosives dumping area????

They're left over munitions from past wars when it was safer and more economical to dump them in the ocean then disassemble them. You can find those grounds every where along the coast. Most likely they are all inert by now from corrosion but I wouldn't want to dive all the way down to one and start tapping on it with a hammer.

As far as threats go there are much easier ways for them to get their hands on explosives then to dive hundreds of feet below the surface to get a rusted out unstable most likely wont work mine. Remember where they come from those things are a lot easier to come by.

Re: Caution, explosives dumping area????

Not unsual for us here in Northern Germany that special ships turn around in a marked area. Few miles from my home were explosives dumped End of WWII. Often they blast controlled old ammunition, mines, torpedos etc.
Sometimes people find phosphor on the beaches but it looks like amber and it burns when in contact with oxygen.
In Spring a new sonar were tested in Kiel Harbour and they found old british mines in the fairway.
Every new construction area has to be checked for duds and there are lots of duds in Germany.

Re: Caution, explosives dumping area????

I had to spend two nights on the street last year here in Munich, when a new building construction site found an old American 500 pounder (underneath what used to be one of the city's loudest and wildest discos, no less) which couldn't be made safe and had to be detonated. (Bombe in München entschärft - Keine Verletzten, viele kaputte Fensterscheiben - YouTube) Thousands of pounds of old munitions still get discovered in Germany annually.

Anyway, those sites marked on the chart are indeed post WW-II sites. Most of the HE used early on (amatol, picrates, etc.) will have become almost inert by chemical decomposition by now, but the later stuff has a longer shelf life and I certainly wouldn't want to experiment.

Some of those areas were also, at some point in time, used for bombing and shelling exercises and those locales would also be marked as dangerous due to unexploded ordnance.

Wreck of a British Armoured Cruiser HMS Drake on Rathlin Island, Northern Island has spread cordite (like uncooked spagetti) around the bay. Children dry it out and use it like sparklers and that is WW1 vintage.

There is a US wreck in the Thames Estuary called the SS Richard Montgomery with 1400 tones on board. Fine whilst underwater but if it went bang.... Sadly it can't now be touched because the wreck and the shell cases are so badly corroded so no chance of disposing of the problem.

As a diver I would regularly find explosives and ammunitions, indeed the brass shell cases are quite valuable. However, the concern was always phosporous which will self ignite in air.

not necessarily useless as folks occasionally get injuries form unexploded ordinance going boom while folks are swimming, as happened in culebra not too long ago.

While living in Micronesia we would see explosives in places that would suprise you...Lots of guys would dive on old ships and retreve un-exploded ordinence to make fish bombs with ,some had a few fingers missing others had whole hands missing! I found 2 grenades(japanese)and a rare snipers rifle with a bullet hole in the side of the mag and a live shell in the chamber ,you could see that he took a round as he was trying to fire on someone and the shell that was hit in the chamber exploded and the guy feel from the tree and all his belongings were in "situ" where he fell..Caves full of rockets and shore guns still pointing out to see are commen in Saipan,Truk,Yap etc...
