Contract for Services in Relation to the Protection of Wrecks Act (1973): Diving investigations on the submarine HMS/M A1

The project was a condition survey of the early 20th century submarine HMS A1, carried out for English Heritage by Wessex Archaeology.

The project involved routine diver survey of the HMS A1 and a site plan of the main elements of the wreck was produced supplemented by photographic and video recording. The impact of illegal diving activities on the wreck was assessed and recommendations were made for its future management. In addition, two geophysical anomalies located in proximity to the wreck were investigated to establish if they were associated with the wreck.

The dataset comprises databases relating to the diver recording system (DIVA) and ROV-track diver tracking, GIS shapefiles for the diver tracklogs and photographs.
