Long-Term Changes in 14 C Age Differences Between Humic Acid and Plant Fragments and Their Links to Past Climate Change
Radiocarbon ( 14 C) dating has been widely used to determine the age of deposits, but there have been frequent reports of inconsistencies in age among different dating materials. In this study, we performed radiocarbon dating on a total of 33 samples from 8-m-long sediment cores recovered from the wetland of the Muljangori volcanic cone on Jeju Island, South Korea. Ten pairs of humic acid (HA) and plant fragments (PF) samples, and three pairs of …
Holocene changes in flooding frequency in South Korea and their linkage to centennial-to-millennial-scale El Niño–Southern Oscillation activity
To trace past changes in flooding frequency, we investigated fluvial sediments in the middle reach of the Nakdong River, South Korea. Sediments with larger grain size, lower total organic carbon percentage, and depleted δ 13 C values in the recovered sediment cores were interpreted as periods of more frequent flooding. Patterns of decreased long-term flooding frequency and vegetation changes during the early to late Holocene were similar to the d…
Middle Holocene environmental change in central Korea and its linkage to summer and winter monsoon changes
To trace the surficial responses of lowlands to past climate change, we investigated δ 13 C in total organic carbon (TOC), C/N ratios, magnetic susceptibility (MS), and silicon (Si) intensity (directly proportional to concentration) in wetland sediments collected from the Gimpo area of central Korea, covering 6600–4600 cal yr BP. Two organic layers with high TOC%, negatively depleted δ 13 C TOC values (− 27 to − 29‰), low MS values, and low Si in…
Holocene environmental change at the southern coast of Korea based on organic carbon isotope (δ13C) and C/S ratios
Relationship between environmental change on Geoje Island, southern coast of Korea, and regional monsoon and temperature changes during the late Holocene
Holocene environmental changes inferred from sedimentary records in the lower reach of the Yeongsan River, Korea
Multidisciplinary paleoproxy data from three sedimentary cores (9.05-m-long MW-2, 16.50-m-long IL-3, and 11.88-m-long JD-1) recovered from the Yeongsan River Estuary of Korea are presented. A marine influence can be observed at 10,400 yr BP (−21 m) and 8600 yr BP (−14 to −12 m) around the Yeongsan River Estuary. However, if we take the macro-tidal setting of the Yeongsan River Estuary into consideration, actual sea level could differ from the dep…
Late Pleistocene vegetation change in Korea and its possible link to East Asian monsoon and Dansgaard–Oeschger (D–O) cycles
Late Pleistocene carbon isotope (δ 13 C) records from a paleolithic sedimentary sequence collected from Baeki, Hongcheon, central Korea, show long-term changes with superimposed short-term isotopic excursions. The δ 13 C value of the sedimentary organic matter, a proxy for past vegetation change, varied from − 26‰ to − 23‰ for the period between 30 and 90 ka, with a long-term variation similar to insolation changes. High-amplitude (− 1‰ to approx…

An assessment of the sand resources in old riverbeds and flood plain deposits within a branch of the Geum River, South Korea
