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.

本项目为英格兰遗产(English Heritage)委托韦塞克斯考古(Wessex Archaeology)开展的20世纪初英国皇家海军HMS A1号潜艇残骸状况勘查项目。本次项目包含对HMS A1号残骸的常规潜水探查，并辅以摄影与视频记录，最终完成了该残骸主体构件的遗址平面图绘制。项目评估了非法潜水活动对该残骸造成的影响，并为其后续管护工作提出了相关建议。此外，项目组对该残骸周边的两处地球物理异常(geophysical anomalies)开展了勘查，以确认其是否与该残骸存在关联。本数据集涵盖与潜水员记录系统(DIVA)及ROV追踪潜水员轨迹系统相关的数据库、用于记录潜水员轨迹日志的GIS形状文件，以及照片资料。
