  • High-resolution radiocarbon chronologies and synchronization of records

    Hajdas, Irka; Lowe, David J.; Newnham, Rewi M. (Swiss and US National Science Foundations, and the National Oceanic and Atmospheric Administration, 2006)
    It is now accepted that the precise dating of certain periods is complicated by extreme variability of atmospheric ¹⁴C content shown at times in the ¹⁴C calibration curve. This complication arises from variations in ...
  • IntCal09 and Marine09 radiocarbon age calibration curves, 0-50,000yeats cal BP

    Reimer, Paula J.; Baillie, Mike G.L.; Bard, Edouard; Bayliss, Alex; Beck, J. Warren; Blackwell, Paul G.; Ramsey, Christopher Bronk; Buck, Caitlin E.; Burr, George S.; Edwards, R. Lawrence; Friedrich, Michael; Grootes, P.M.; Guilderson, Thomas P.; Hajdas, Irka; Heaton, Timothy J.; Hogg, Alan G.; Hughen, Konrad A.; Kaiser, K.F.; Kromer, B.; McCormac, F.G.; Manning, S.W.; Reimer, Ron W.; Richards, D.A.; Southon, John R.; Talamo, Sahra; Turney, Chris S.M.; van der Plicht, Johannes; Weyhenmeyer, Constanze E. (Arizona Board of Regents on behalf of the University of Arizona, 2009)
    The IntCal04 and Marine04 radiocarbon calibration curves have been updated from 12 cal kBP (cal kBP is here defined as thousands of calibrated years before AD 1950), and extended to 50 cal kBP, utilizing newly available ...
  • IntCal13 and Marine13 radiocarbon age calibration curves 0-50,000 years cal BP

    Reimer, Paula J.; Bard, Edouard; Bayliss, Alex; Beck, J. Warren; Blackwell, Paul G.; Bronk Ramsey, Christopher; Buck, Caitlin E.; Cheng, Hai; Edwards, R. Lawrence; Friedrich, Michael; Grootes, Pieter M.; Guilderson, Thomas P.; Haflidason, Haflidi; Hajdas, Irka; Hatté, Christine; Heaton, Timothy J.; Hoffmann, Dirk L.; Hogg, Alan G.; Hughen, Konrad A.; Kaiser, K. Felix; Kromer, Bernd; Manning, Sturt W.; Niu, Mu; Reimer, Ron W.; Richards, David A.; Scott, E. Marian; Southon, John R.; Staff, Richard A.; Turney, Christian S. M.; van der Plicht, Johannes (University of Arizona, 2013)
    The IntCal09 and Marine09 radiocarbon calibration curves have been revised utilizing newly available and updated data sets from 14C measurements on tree rings, plant macrofossils, speleothems, corals, and foraminifera. The ...
  • Selection and treatment of data for radiocarbon calibration: An update to the International Calibration (IntCal) criteria

    Reimer, Paula J.; Bard, Edouard; Bayliss, Alex; Beck, J. Warren; Blackwell, Paul G.; Bronk Ramsey, Christopher; Brown, David M.; Buck, Caitlin E.; Edwards, R. Lawrence; Friedrich, Michael; Grootes, Pieter M.; Guilderson, Thomas, P.; Haflidason, Haflidi; Hajdas, Irka; Hatté, Christine; Heaton, Timothy J.; Hogg, Alan G.; Hughen, Konrad A.; Kaiser, K. Felix; Kromer, Bernd; Manning, Sturt W.; Reimer, Ron W.; Richards, David A.; Scott, Marian E.; Southon, John R.; Turney, Christian S. M.; van der Plicht, Johannes (University of Arizona, 2013)
    High-quality data from appropriate archives are needed for the continuing improvement of radiocarbon calibration curves. We discuss here the basic assumptions behind 14C dating that necessitate calibration and the relative ...
  • Timing of the late-glacial climate reversal in the Southern Hemisphere using high-resolution radiocarbon chronology for Kaipo bog, New Zealand

    Hajdas, Irka; Lowe, David J.; Newnham, Rewi M.; Bonani, Georges (Academic Press, 2006-03)
    The pattern of climate change in the Southern Hemisphere during the Younger Dryas (YD) chronozone provides essential constraint on mechanisms of abrupt climate change only if accurate, high-precision chronologies are ...
