The Royal Naval survey ship HMS Enterprise is already making significant inroads into navigational safety in Dubai having discovered the previously uncharted wrecks of two dhows in Port Rashid Harbour.
Most of the data has been captured by the Royal Navy over a considerable period so it's probably prudent to point out that its ships rely on it too. Apart from foreign training and fishery protection, the HO is one of the few cash cows the MoD still has, especially since the losses of DESO to UK Trade & Investment in April 2008 and the Met Office to the Department for Business, Innovation and Skills in July last year.
A brief history of the United Kingdom Hydrographic Office
The UKHO Archive started life as an accumulation of charts, surveys, reports, books and atlases held within the Admiralty in London. When the Hydrographic Office was established in 1795 the first Hydrographer to the Admiralty Board, Alexander Dalrymple FRS, was charged with arranging and digesting a ‘considerable mass of information’ and was given a clerk to take ‘care of the plans and charts’ that had accumulated in the Admiralty over nearly two centuries. With the expansion in surveying capability after 1815 the number of surveys and, subsequently, printed charts in the Hydrographic Office expanded...
Today the Archive holds over 600,000 surveys, books, charts and files, containing millions of individual letters, reports, photographs and documents. Currently the Archive is undertaking a project to transfer its historical material to The National Archives based at Kew, which involves cataloguing over 250 metres of departmental documents dating from the early 1800s. This is estimated to take three years and will improve access to an important collection of historical naval and hydrographic information.
Do they have a chap or chapess dedicated to going back to ARRSE to record the comments of the brutal and licentious soldiery [(c) Kipling misquoting somebody else] so that the bosses can weep salt tears over the ignorance displayed?
As to the Olympus, it is the general order of things that when a submarine fails to return it is very often not possible to determine where she lies. There are probably several of our boats still out there somewhere .. as the German song has it, No roses grow on a sailor's grave.
