Three-dimensional (3D) modelling is becoming a ubiquitous technology for the interpretation of cultural heritage objects. However most 3D models are based on geomatic data such as surveying, laser scanning or photogrammetry and therefore rely on the subject of the study being visible. This chapter presents the case study of , a submerged and partially buried barge wrecked near the town of Morgan in South Australia. was reconstructed using two alternative approaches; one based on a combination of historic photographs and computer graphics and the second based on geophysical data from electrical resistivity tomography (ERT). ERT has been rarely used for maritime archaeology despite providing 3D representation under challenging survey conditions, such as in shallow and turbid water. ERT was particularly successful on for mapping the external metal cladding, which was recognisable based on very low resistivity values. An alternative 3D model was created using historic photographs and dimensions for in combination with information from acoustic geophysical surveys. The excellent correspondence between these models demonstrates the efficacy of ERT in shallow maritime archaeology contexts.

This chapter outlines an opportunistic yet innovative approach to developing a 3D visualization of HMS , a Town Class light cruiser sunk during the First World War on the Yorkshire coast, England. The results of a multibeam echosounder survey of the seabed were combined with photogrammetry and laser scanning of the original builder’s model of HMS , which is in store in the collections of the Imperial War Museums (IWM). The visualization, made available via , helped to generate considerable public and media interest in an important heritage asset. This chapter also comments on the role of visualizations in engaging people for whom underwater archaeology is otherwise inaccessible, and considers the potential for visualizations to integrate research and prompt further investigation.

Beacon Virtua is a project to document and virtually preserve a historically significant offshore island as a virtual reality experience. In 1629, survivors of the wreck of VOC ship took refuge on Beacon Island, Western Australia, followed by a mutiny and massacre. In the 1950s the island became the base of a successful fishing industry, and in 1963 human remains from were located. The fishing community has recently been moved off the island to protect and preserve the site and allow a thorough archaeological investigation of the island. Beacon Virtua exposes users to the history of both the shipwreck survivors and the fishing community. The project uses the virtual environment development software Unity to present a simulation of the island, with 3D models of buildings and jetties, photogrammetric 3D reconstructions of graves and other features, 360° photographic panoramas, and information on the history of the island. The experience has been made available on a wide range of different platforms including via a web-page, as part of an exhibition, and on head mounted displays (VR headsets). This chapter discusses the features included in Beacon Virtua, the storytelling techniques used in the simulation, the challenges encountered and solutions used during the project.

Archaeologists have aspired to a seamless integration of terrestrial and marine survey since maritime archaeology began to emerge as a distinct sub-discipline. This chapter will review and discuss how 3D technology is changing the way that archaeologists work, blurring the boundaries between different technologies and different environments. Special attention is paid to the integration of data obtained from aerial and underwater methods. Maritime archaeology is undergoing an explosion of site recording methods and techniques which improve survey, excavation and interpretation, as well as management and conservation of material culture, protected sites, and cultural landscapes. An appraisal of methods and interpretive tools is therefore necessary as well as a consideration of how theoretical concepts of maritime landscapes are finding new expressions in practice. A thematic focus is placed on integrating land and sea through case studies of maritime archaeological sites and material which range chronologically from the recent past to several thousand years before present.
