| Outline of Final Research Achievements |
Radiocarbon dates do not equate directly with calendar time and must be corrected using a calibration curve. A calibration data set during the past 50 ka (e.g. IntCal13) has from radiocarbon date of known-age samples such as wood, fossil coral, cave deposit (stalactite) and lacustrine varve sediments. The high-resolution 14C dating has been conducted for the terrestrial plant remains in a sediment samples from the deepest part of the Dead Sea (the ICDP 5017-1 site), which was recovered by the Dead Sea Deep Drilling Project (DSDDP) under the auspices of the International Continental Scientific Drilling Program (ICDP). The data set were compared with the U/Th-date of aragonite deposited chemically from lake water to validate and improve the latest calibration data: IntCal13.
