Since watching the BBC documentary Britain’s Secret Seas a couple of days ago I’ve been fascinated by 3D underwater sonar scans. There are a couple of uses of the technology, but the documentary concentrated on the issue of preserving historic shipwrecks. Basically sonar scan is used to create high-resolution threedimensional images of the wrecks which are in that way digitally preserved, as salvaging would be too costly, if not impossible.
ADUS specialises in sonar surveying & visualisation and there are many fascinating pictures on their website.
There are also 2 very interesting articles on Wired.co.uk about a planned sonar scan of the Titanic and about the completed scan of a Russian nuclear submarine (picture above). Interestingly, there is another article on the Titanic sonar scan operation here - can’t wait to see the whole thing.
The documentary Britain’s Secret Seas - The Wild North is still available to watch on the BBC iPlayer and it features all sorts of really interesting things, fluorescent sea creatures, for example, amazing! (46.30min)
With many thankings to @lesleyfarrow and her kind collection of carefully selected Eurovision entries through the ages, as well as to @woollytoe and @rita_c_sampaio for making it such a brilliant weekend
