Underwater archaeology

Stefan Krojer is a research associate and PhD candidate at the Vienna Institute for Archaeological Science (VIAS) at the University of Vienna. His research and teaching focus on the application of geophysical and imaging techniques for the investigation of underwater archaeological sites in Austria and internationally. As part of the FWF-WEAVE project “Drowned Villages of the Scheldt. A Geoarchaeological Study,” he investigates submerged historical settlements in the Scheldt Delta (Netherlands) using high-resolution sonar technologies. In parallel, he is involved in several projects concerning the documentation of underwater archaeological sites in Austrian lakes – among others in close collaboration with and on behalf of the Kuratorium Pfahlbauten (Board of Pile Dwellings), within the framework of the UNESCO World Heritage Site “Prehistoric Pile Dwellings around the Alps.” Krojer is a certified scientific diver with decades of experience in technical diving. He also works as an instructor and examiner for diving instructors and technical divers, combining this practical expertise with academic research and teaching. He is the founder of a specialized company for underwater archaeological prospection and currently teaches at the Department of Prehistoric and Historical Archaeology at the University of Vienna in the field of underwater archaeological surveying. His methodological focus lies in high-resolution, large-scale and minimally invasive prospection using sonar technology (including side-scan, multibeam, and sub-bottom systems) and underwater photogrammetry.
