  • The remains and relics such as wood vessel, shell middens and acorn hollows related to marine environments were excavated at Bibong-ri, Changnyeong-gun, Gyeongsangnam-do, South Korea, approximately 70km apart from the Nakdong River mouth. The sea-level changes were reconstructed based on characteristics of shell middens and acorn hollows, sedimentary facies, AMS dating, and diatom analysis. The shell middens and acorn hollows were constructed during the early Neolithic Age and provide information on the paleo-sea level, because of influences of marine processes. The sedimentary facies are classified into a bedrock, base gravel and Holocene sediment (marine, terrestrial and back marsh sediments), upward. The sea level fluctuated during the middle Holocene is in harmony with those in Sejuk-ri, Ulsan and Pyeongtaek. In particular, the sea level at Bibong-ri of study area was higher than the mean high tidal level in Gimhae by approximately 1m during 5,000yr BP and maintained the stable condition during 4,000yr BP.
