In this paper several recent case studies of near surface geophysical applications in Greece are presented. The case studies are focused mostly in archeological site investigation, a field which is of high interest in Greece due to its reach historical heritage. The growing construction works in several parts of Greece as well as the increasing public interest in exploring and preserving cultural heritage lead to an increase of the application of nearsurface geophysics techniques as a preliminary investigation tool prior to engineering and archeological excavation works. Research efforts, presented in this work, are focused to extending and adapting standard nearsurface techniques in order to be made more effective for archaeological site investigation. The presented case studies involve not only standard field investigation procedures but also novel approaches such as the use of non-spike electrodes, efficient measuring and instrumentation strategies, unusual configurations and measurement environments. Overall it shown that efficient and state-of-art nearsurface geophysical techniques used for archaeological prospection purposes provide significant archaeological and structural information valuable for archeologists, engineers and conservation scientists.

In order to survey archaeological sites, drilling and excavation are carried out at the final stage. However, at the preliminary stage, non-excavation geophysical prospection is used for assessing underground archaeological ruins. Among the geophysical prospecting techniques, Ground Penetration Radar (GPR) prospection has effectively been applied to historical sites due to its high resolution at shallow depths. In this study, the GPR prospection was conducted to find underground ruins near Suseong-Dang, the place of ancient rituals in Buan area, Korea. First, the GPR prospection was conducted at three sites (Site-1, 2, and 3), and subsequently, the GPR prospection was carried out at Site-3 in more detail. As a result of the prospection, the underground layered structure of the survey area consists of three layers, which are soil layer, weathered rock, and sound rock from the surface. And the GPR anomaly to the archaeological structure was clearly identified at around 100-cm depth showing est-west direction that is parallel to the long-axis array. This GPR anomaly of irregular geomorphological features and intermittent distribution may be related to the ritual remains found in Suseong Dang. The GPR prospection could be effectively used to detect archaeological sites or remains buried in the ground.

To test the applicability of resistivity survey methods for the archaeological prospection of a large-scale tumulus, a three-dimensional resistivity survey was conducted at the $3^{rd}$ tumulus at Bokam-ri, in Naju city, South Korea. Since accurate topographic relief of the tumulus and electrode locations are required to obtain a high resolution image of the subsurface, electrodes were installed after making grids by threads, which is commonly used in the archaeological investigation. In the data acquisition, data were measured using a 2 m electrode spacing with the line spacing of 1 m and each survey line was shifted 1 m to form an effective grid of 1 m ${\times}$ 1 m. Though the 3-D inversion of data, we could obtain the 3-D image of the tumulus, where we could identify the brilliant signature of buried tombs made of stones. The results were compared with the previous excavation results and we could convince that a 3-D resistivity imaging method is very useful to investigate a large-scale tumulus.
