چکیده انگلیسی
The marine reservoir effect was measured by comparing the radiocarbon ages of shell and plant pairs obtained from the same horizons of a sediment core around the Yeongsan River in the southwestern part of the Korean Peninsula. The Holocene sediment formed in five environments: tidal flat, inner bay, shallow marine, flood plain, and embankment from bottom to top. The tidal flat and shallow marine sediments should be good indicators of marine reservoir effect, as they formed in coastal environments where it was easy to access not only marine shells but also terrestrial plants. Some old detritus could be identified and removed, based on reliable accumulation curves and sedimentological interpretation. Hence, the age differences between the plants and shells could be successfully evaluated, and they indicated that the marine reservoir effect varied over time between 0 and 500 years. There was an increase of this effect at ca. 8000 cal year BP and a decrease at ca. 5000 cal year BP, possibly linked with coastal environment changes induced by sea level changes and by changes in the circulation of seawater.
