Underwater Excavation Records Using Underwater Acoustic Survey: A Case Study in South Korea

The most effective method for surveying underwater archeological sites is visually identifying areas with relics or remains through diving surveys. However, during excavations, it difficult to obtain images in turbid water. Furthermore, on-site costly and time-consuming. Marine acoustic geophysical survey equipment not significantly affected by turbidity, excavations often rely on surface inspections. This study aimed improve existing excavation imaging the application of methods. Underwater surveys were conducted via marine devices at three historically significant South Korea: Dangampo, Nakwoldo Island, Battle Myeongnyang. At Dangampo site, using different sonar devices—side scan sonar, multibeam echo sounder, scanning sonar—and results compared; was effective. methodology further refined Myeongnyang sites. Results show that can produce are more accurate than drawings produced even environments. Moreover, applied conjunction high-frequency exploration techniques, increase reliability investigations buried relics.
