  • Interhemispheric gradient of atmospheric radiocarbon reveals natural variability of Southern Ocean winds

    Rodgers, K.B.; Fletcher, S.E.M.; Bianchi, D.; Beaulieu, C.; Galbraith, E.D.; Gnanadesikan, A.; Hogg, Alan G.; Iudicone, D.; Litner, B.; Naegler, T.; Reimer, Paula J.; Sarmiento, J.L.; Slater, R.D. (Copernicus Publications, 2011)
    Tree ring Δ¹⁴C data (Reimer et al., 2004; McCormac et al., 2004) indicate that atmospheric Δ¹⁴C varied on multi-decadal to centennial timescales, in both hemispheres, over the pre-industrial period AD 950–1830. Although ...

  • Investigating the interhemispheric ¹⁴C offset in the 1st millennium AD and assessment of laboratory bias and calibration errors

    Hogg, Alan G.; Palmer, Jonathan G.; Boswijk, Gretel; Reimer, Paula J.; Brown, David (Arizona Board of Regents on behalf of the University of Arizona, 2009)
    Past measurements of the radiocarbon interhemispheric offset have been restricted to relatively young samples because of a lack of older dendrochronologically secure Southern Hemisphere tree-ring chronologies. The Southern ...

  • 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, Chris 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 ...

  • SHCal04 Southern Hemisphere Calibration, 0–11.0 cal kyr BP

    McCormac, F.G.; Hogg, Alan G.; Blackwell, Paul G.; Buck, Caitlin E.; Higham, Thomas F.G.; Reimer, Paula J. (University of Arizona, Department of Geosciences, 2004)
    Recent measurements on dendrochronologically-dated wood from the Southern Hemisphere have shown that there are differences between the structural form of the radiocarbon calibration curves from each hemisphere. Thus, it ...

  • SHCal13 Southern Hemisphere calibration, 0–50,000 years cal BP

    Hogg, Alan G.; Hua, Quan; Blackwell, Paul G.; Niu, Mu; Buck, Caitlin E.; Guilderson, Thomas P.; Heaton, Timothy J.; Palmer, Jonathan G.; Reimer, Paula J.; Reimer, Ron W.; Turney, Chris S.M.; Zimmerman, Susan R. H. (The University of Arizona, 2013)
    The Southern Hemisphere SHCal04 radiocarbon calibration curve has been updated with the addition of new data sets extending measurements to 2145 cal BP and including the ANSTO Younger Dryas Huon pine data set. Outside the ...
