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.
