Submersible ground penetrating radar (SGPR) – chances and limits for underwater investigations
Results of submerged ground penetrating radar (SGPR) measurements show spectacular detailed depositional structures of lake floor sediments, which could not be revealed with any other geophysical method yet. Due to its very high resolution, GPR is particularly suitable for archeological prospection on land surfaces and now on lake floors. A case study showed that a submerged archaeological site in Lake Constance (boulder mounds, the so-called “Hügelis”) is interfingering with the sedimentary record. Depositional history reveals that the site must be human-made and dates back to the prehistorical period. 14C ages of sediment and wood poles proved Neolithic age of the more than 170 boulder mounds comprising over 80,000 metric tons of rock.
