With geophysical research methods, we can easily determine the location and depth of ports, docks, cities, historical ships or shipwrecks that are submerged in seas and lakes, seen or buried on the sea floor.

Archaeological researches at sea, according to the nature of the structure to be investigated;
        - Ultra High Resolution Seismic Reflection
        - Gradiometer,
        - Multibeam Sonar
        - Georadar ( in Freshwater)

We use one or more of the methods together. We use GNSS systems with high positioning accuracy simultaneously in all measurements we perform in seas and lakes. Thus, we obtain the archaeological maps of the historical structures determined as a result of the measurements.
