Atmospheric Radiocarbon Calibration Beyond 11,900 cal BP from Lake Suigetsu Laminated SedimentsKitagawa, Hiroyuki; van der Plicht, Johannes (Department of Geosciences, The University of Arizona, 2000-01-01)This paper presents an updated atmospheric radiocarbon calibration from annually laminated (varved) sediments from Lake Suigetsu (LS), central Japan. As presented earlier, the LS varved sediments can be used to extend the radio-carbon time scale beyond the tree ring calibration range that reaches 11,900 cal BP. We have increased the density of 14C measurements for terrestrial macrofossils from the same core analyzed previously. The combined data set now consists of 333 measurements, and is compared with other calibration data.
