چکیده انگلیسی
Applying these equations to bulk shell δ18Oar and δ13Car in the 20 m sediment core, very similar salinity histories were reconstructed from either oxygen or carbon isotope ratio data. At the beginning of lacustrine sediment deposition (8000-7500 14C yr B.P.) paleosalinity of the bottom water in the central portion of Nakaumi Lagoon increased from 22 to 32 PSU. During the 7500-5500 yr B.P. interval, which approximately corresponds to the Holocene climatic optimum and high sea-level stand, salinity ranged from 27 to 37 PSU. After 5500 yr B.P. salinity lessened under the cooling climate, with a minimum value of 24-27 PSU at 3000-1000 yr B.P. The results show a consistent relationship between climate change, sea-level, and salinity in the lagoon during the Holocene.
