  • Bayesian evaluation of the southern hemisphere radiocarbon offset during the holocene

    Hogg, Alan G.; Ramsey, Christopher Bronk; Turney, Chris S.M.; Palmer, Jonathan G. (Arizona Board of Regents on behalf of the University of Arizona, 2009)
    While an interhemispheric offset in atmospheric radiocarbon levels from AD 1950–950 is now well established, its existence earlier in the Holocene is less clear, with some studies reporting globally uniform 14C levels while ...

  • IntCal04 terrestrial radiocarbon age calibration, 0–26 cal kyr BP

    Reimer, Paula J.; Baillie, Mike G.L.; Bard, Edouard; Bayliss, Alex; Beck, J. Warren; Bertrand, Chanda J.H.; Blackwell, Paul G.; Buck, Caitlin E.; Burr, George S.; Cutler, Kirsten B.; Damon, Paul E.; Edwards, R. Lawrence; Fairbanks, Richard G.; Friedrich, Michael; Guilderson, Thomas P.; Hogg, Alan G.; Hughen, Konrad A.; Kromer, Bernd; McCormac, Gerry; Manning, Sturt W.; Ramsey, Christopher Bronk; Reimer, Ron W.; Remmele, Sabine; Southon, John R.; Stuiver, Minze; Talamo, Sahra; Taylor, F.W.; van der Plicht, Johannes; Weyhenmeyer, Constanze E. (University of Arizona, Department of Geosciences, 2004)
    A new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace IntCal98, which extended from 0–24 cal kyr BP (Before Present, 0 cal BP ...

  • 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 ...

  • The New Zealand Kauri (Agathis Australis) Research Project: A Radiocarbon Dating Intercomparison of Younger Dryas Wood and Implications for IntCal13

    Hogg, Alan G.; Turney, Chris S.M.; Palmer, Jonathan G.; Southon, John R.; Kromer, Bernd; Ramsey, Christopher Bronk; Boswijk, Gretel; Fenwick, Pavala; Noronha, Alexandra; Staff, Richard; Friedrich, Michael; Reynard, Linda; Guetter, Dominik; Wacker, Lukas; Jones, Richard T. (The University of Arizona, 2013)
    We describe here the New Zealand kauri (Agathis australis) Younger Dryas (YD) research project, which aims to undertake Δ14C analysis of ~140 decadal floating wood samples spanning the time interval ~13.1–11.7 kyr cal BP. ...

  • Revised calendar date for the Taupo eruption derived by ¹⁴C wiggle-matching using a New Zealand kauri ¹⁴C calibration data set

    Hogg, Alan G.; Lowe, David J.; Palmer, Jonathan G.; Boswijk, Gretel; Ramsey, Christopher Bronk (Sage, 2011)
    Taupo volcano in central North Island, New Zealand, is the most frequently active and productive rhyolite volcano on Earth. Its latest explosive activity about 1800 years ago generated the spectacular Taupo eruption, the ...
