Geophysical Survey of Gyeonggi Bay

경기만(京畿灣) 해저지층구조(海底地層構造)에 대(對)하여

Seismic and side scan sonar traverses in the inner part of Gyeonggi bay was completed during 1976 and 1977 to depict the distribution and thickness of holocene sediments. Special attention was given to the locations of sand and gravel resources. The area of sand sediments is about $50km^2$ mostly distributed in outer part of inner bay. Maximum thickness of sand sediments is 40m with the averge of 10-15m. Tidal current prevailing in the bay seems to be the most important agent modifying the distributions and thickness of sediments in the Gyeonggi bay.
