Data Collection for a Virtual Museum on the Underwater Survey at Kas, Turkey

Cataloged from PDF version of article.The Underwater Archaeological Survey Project at Kas¸, on the Lycian coast of Turkey, has emerged from a need to document, research and preserve underwater sites in the area surrounding the town of Kas¸. This region has stood out in recent decades as a centre of underwater tourism, enabling countless divers with a wide range of interests and backgrounds to explore the coastal depths of the Mediterranean around this popular town. Rising numbers of recreational divers and increased underwater access to sites of potential historical and archaeological significance has generated an aspiration for their contribution to and participation in a variety of underwater survey projects. Our project has emerged with the intention of bridging this gap between trained specialists and divers by identifying the underwater cultural heritage for future protection and dissemination

Investigation of Late Roman Settlement on Dana Island, Bogsak Archaelogical Survey Project

Purdue researchers participated in the 2019 season of the Bogsak Archaeological Survey Project in south coastal Turkey. Prof. Ayman Habib and Evan Flatt of CE used a drone to conduct LIDAR and camera mapping of the Late Roman harbor remains of Dana Island (approximately 250-800 AD). The remains, including vast quarry trenches and terraces of houses, cisterns, and churches, are covered in dense, nearly impenetrable garrigue brush, making standard architectural mapping laborious, inaccurate, and hazardous. The results of the LIDAR mapping should reveal a detailed map of obscured remains in real world coordinates, making it possible to map the remains virtually

Submarine and coastal karstic groundwater discharges along the Southwestern Mediterranean coast of Turkey

A 120 km-long part of the southwestern coast of Turkey, with well-developed karst terrain in contact with the sea, has been investigated by systematic diving surveys to determine the submarine groundwater discharges (SGDs). The physical, chemical and isotopic data have been used to determine the rate of the fresh groundwater end member (FEM) and its temporal dynamics. About 150 SGDs have been detected by diving surveys employed mostly up to a depth of 30 m below sea level (bsl). Among those, 15 SGDs are in the form of coastal or submarine caves with entrances ranging between sea surface and 40 m bsl. The FEM contribution in SGDs ranges from a few percent to more than 80%. Stable isotope data suggest a range of mean recharge area elevations extending from the coast to more than 1,000 m inland. In many of the SGDs, the FEMs are characterized by tritium-based residence times ranging from recent to several decades. Hypothetical geochemical calculations of mixing between freshwater and seawater end members reveal that more than 45% of freshwater contribution is required for karst development in the SGDs. Models suggest a threshold pH of 7.6 or lower for the carbonate rock dissolution. © 2010 Springer-Verlag

UMA PLATAFORMA WEB PARTICIPATIVA APOIADA POR REALIDADE AUMENTADA PARA LOCALIZAR CARAVANÇARAIS (KHANS) ANATOLIANOS ORIENTAIS

The focus of this research is digital heritage in emergence. This study deals with how to use digital media tools to collect information about caravanserais (khans) to digitise lost heritage attributes. The study involved researchers compiling information about these caravanserais from references, and digitally mapping   and generating identification tags based on the information in the sources. The researchers generated an online platform for information dissemination, consisting of the projection augmented model of the khans, and participatory web archive platform for crowdsourcing information. The interaction with users through the augmented representation and participation are the main features of this study, which represents a proposal for a method of interactive digital archiving. The digital khans can be exhibited in a virtual museum, or to be used as a database for those wishing to explore vanished heritage. The digital archiving project contributes to knowledge generation in placemaking using digital mediums and methods.O foco da presente investigação é o património digital. O estudo trata da utilização de ferramentas digitais na recolha de informações sobre khans[1] (caravançarais) para digitalizar atributos do património julgado perdido. No âmbito do estudo, os investigadores compilaram informações sobre estes khans, cartografaram digitalmente e geraram etiquetas de identificação a partir das referências recolhidas. Assim, foi gerada uma plataforma online com vista à divulgação da informação, e que inclui o modelo ampliado dos khans; igualmente, foi criada uma plataforma web participativa (crowdsourcing) que arquiva a informação recolhida. A interação com o utilizador, através da representação mediante a realidade aumentada, permite a participação que é marca identitária deste estudo que visa a construção de um arquivo digital interativo. Os khans digitais são expostos num museu virtual, disponibilizando uma base de dados que permite explorar o património desaparecido. Este projeto de arquivamento contribui para a geração de conhecimento em modo de placemaking, utilizando meios e métodos digitais

4D Printing on Textiles: developing a file to fabrication framework for self-forming, composite wearables

This research is investigating the development of self-forming wearable composite structures by 3D printing semi-elastic embossed patterns out of semi-elastic Thermoplastic Polyurethane 95 filament on pre-stretched textiles and releasing the stress after the printing has been completed. In particular, we will present and compare two methods of ‘file to fabrication’ techniques for generating self-forming textile shell structures: one based on printed patterns related to their stress line simulation and a second based on modified geometrical patterns in relation to their curvature analysis. Furthermore, we will investigate the buckling degree of the composites in relation to their fabric thickness and elasticity. Our findings will emphasize the advantages and challenges of each method as well as present a comparative table chart highlighting the relationship between material properties, pattern geometry and the formal vocabulary of the composite shells

Web-based Information System for Virtual Museum of Underwater Cultural Heritage in Turkey

This paper presents a developed web-based information system using the data collected during underwater surveys conducted on the coastal region of Turkey. Divers from a variety of professional backgrounds collected data by keeping the archaeological artifacts in their original context. By collecting visual, geographical and descriptive data using structured datasheets, the artifacts are transferred into the digital domain. Through the analysis of these methods, an information system is developed aiming for the contribution of all interested parties in a collaborative manner. Combined with Google Maps, the database illustrates the initial technological steps towards the development of a virtual museum

Envisioning Ambiances of the Past

Outdoor museums of archaeological excavations function as sites of both scientific research and public display. Often, long-term archaeological research means postponing the preparation of the site for visitors. This paper focuses on digital tools for the representation of architectural reconstructions, i.e. possibilities for representing a range of hypotheses regarding the past ambiances of the ancient city. It proposes an augmented immersive revisit of the cultural heritage through mobile devices. Based on mobile phones’ current technical capacities, which enables rendering of 3D content combined with camera input, we developed the proposed mobile AR application for mobile Android devices. TeosAR offers a real-time, in-situ 3D depiction and visualization of architectural artifacts of the ancient city implementing model-based tracking methods

GIS in Archaeology: the Pedestrian Survey of Dana Island in Turkey

An international team of archaeologists conducted a surface survey of the remains on Dana Island, ancient Pithussae, near Silifke in south Coastal Turkey. The island sits 2 km offshore and is uninhabited. Architectural remains of stone quarries, large cisterns, houses and churches extend approximately 1.6 km along its western coast. At the crest of the mountain that rises above the shore stands the remains of an Iron Age fortress incorporated into later Byzantine structures. Relying on a base map constructed of the Google earth view of the island, digitized topographical maps, and an aerial photograph from 1990, the pedestrian team constructed a project GIS for the remains investigated during the walking survey. The team some 7 transects of survey units amid the remains along the shore as well as a brief prospective survey of the fortress above

Radioactivity of phosphate ores from Karatas-Mazidag phosphate deposit of Turkey

The specific activities of U-238, Ra-226, Th-232 and K-40 in the composite samples of phosphate ores of type I (grey-coloured ore, with high P2O5 (21-35%) and low calcite content) and of type II (grey coloured calcite ore, with low P2O5 content (5-17%)) of Karatas-Mazidag phosphate deposit, Turkey, have been determined by gamma spectrometry together with phosphatic animal feed ingredients. The concentrations of 238U, Ra-226, Th-232 and K-40 were found to be up to 557, 625, 26 and 297 Bq.kg(-1), respectively. Radium equivalent activities of samples examined were calculated and compared with those given in the literature. Uranium concentration of the individual phosphate samples, from which composite samples of ores of type I and II have been prepared, were found to show an increasing trend with increasing P2O5 and F concentrations

Augmenting Psychological Restorativeness towards Immersive Design of Underwater Ambiance

Discussions of the relationship between humanity and built environment usually focus on the human’s relationships with the earth’s surface. Less attention has been given to underwater environments, a relatively underexplored research area at the intersection of user experience design and psychology. This paper shows the initial findings of experiments on divers, which can guide the design of augmented reality tools for underwater environment. The comparative evaluation process demonstrates an increase in psychological restorativeness of users in relation to ambiance design, indicating a difference between a specifically designed environment and a naturally vacant area for first time divers. Future studies will explore immersive design of underwater ambiance through augmented reality tools, proposed as a product design and framework, in order to improve psychological restorativeness
