On Sunday 6 October 2014, Wessex Archaeology and members of BSAC 326 (Canterbury Divers) and BSAC 501 (Folkestone) diving clubs carried out a photographic survey of the First World War German submarine UB 78. The work was carried out from the Dover-based charter boat Neptune and was part of a programme of work connected with the 1914–18 centenary being carried out for English Heritage.
The UB 78 was sunk in April 1918 when it detonated a mine whilst trying to find a way through the heavily defended Dover Straits. As can be seen from the photographs taken by Wessex Archaeology’s own Paolo Croce, the underwater visibility on this wreck off Folkestone proved to be unusually good.
