Having seen in recent years a couple of survey RIBs festooned with sensors operating around the coast working closer to shore than anything else, I learned they were doing a new seabed survey and been keen to see their output.
Check this out but only if you have time. 3D models from sonar surveys of some 160 wrecks in Irish waters. Fascinating, especially if they're local or you've sailed over or dived on them.
Interesting thanks. Are all WW1? Is it a continuation of THIS? It would be nice to have a map, as I'd bet local knowledge could fill in several blanks.
edit - scrolling down past the numbers I found ecent ones - e.g. Kowloon Bridge.
They've let the location of new unknowns secret to avoid looting which had been a possible for years. But they're must be done interesting targets to be legally explored In the coming years.
