Wrecks on the Seabed R2: Assessing Evaluating and Recording (Unknown)

The project comprised the development and testing of a number of methodologies for the rapid assessment, evaluation and recording of wreck sites. The main aim of the project was to provide industry, regulators and contractors with a framework for the incremental, decision-oriented investigation of wreck sites and with guidance on their archaeological assessment, evaluation and recording. The objectives were: - Develop and refine methodologies for assessing, evaluating and recording sites in deeper water. - Assess the effectiveness of undertaking archaeological recording using remote operated vehicle (ROV) and geophysical techniques only. - Assess environmental issues (e.g. depth, distance from port, fetch) in respect of working on sites in deeper water. - Assess infrastructure issues (e.g. anchoring, tow cable handling, umbilical handling) in respect of working on sites in deeper water. Year two of Round two of the Wrecks on the Seabed project comprised deep water ROV survey of three wrecks. This dataset relates to the second of these wrecks, an unknown steamer of possible First World War date and comprises databases relating to the Wessex Archaeology DIVA dive recording system, GIS shapefiles for the dive tracklogs of the ROV and video stills from the survey.

本项目开发并测试了一系列用于沉船遗址快速勘查、评估与记录的方法体系。本项目的核心目标是为行业、监管机构及承包商提供一套用于沉船遗址渐进式决策导向型勘查的框架，以及沉船遗址考古勘查、评估与记录的专业指南。项目目标如下：
- 开发并优化深水遗址勘查、评估与记录的方法体系；
- 评估仅采用遥控无人潜水器（Remote Operated Vehicle, ROV）及地球物理技术开展考古记录工作的实际效果；
- 针对深水遗址作业涉及的环境因素（如水深、距港口距离、风区长度）开展评估；
- 针对深水遗址作业涉及的配套设施问题（如锚泊、拖缆操作、脐带缆操作）开展评估。

“海底沉船项目”（Wrecks on the Seabed）第二轮的第二年度工作内容为对三艘沉船开展深水遥控无人潜水器（ROV）勘测。本数据集对应其中第二艘沉船——一艘年代可能属于第一次世界大战时期的不明蒸汽船，相关数据包含韦塞克斯考古（Wessex Archaeology）DIVA潜水记录系统配套数据库、遥控无人潜水器航行轨迹记录的地理信息系统（Geographic Information System, GIS）形状文件，以及本次勘测的视频静帧图像。
