  • Anomalous mid-twentieth century atmospheric circulation change over the South Atlantic compared to the last 6000 years

    Turney, Chris S.M.; Jones, Richard T.; Lister, David; Jones, Phil; Williams, Alan N.; Hogg, Alan G.; Thomas, Zoë A.; Compo, Gibert P.; Yin, Xungang; Fogwill, Christopher J.; Palmer, Jonathan; Colwell, Steve; Allan, Rob; Visbeck, Martin (IOP Publishing Ltd, 2016)
    Determining the timing and impact of anthropogenic climate change in data-sparse regions is a considerable challenge. Arguably, nowhere is this more difficult than the Antarctic Peninsula and the subantarctic South Atlantic ...
  • 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 ...
  • Evidence for suppressed mid-Holocene northeastern Australian monsoon variability from coral luminescence

    Lough, J.M.; Llewellyn, L.E.; Lewis, S.E.; Turney, Chris S.M.; Palmer, Jonathan G.; Cook, C.G.; Hogg, Alan G. (American Geophysical Union, 2014)
    Summer monsoon rainfall in northeastern (NE) Australia exhibits substantial interannual variability resulting in highly variable river flows. The occurrence and magnitude of these seasonal river flows are reliably recorded ...
  • 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 ...
  • Is there any Evidence for Regional Atmospheric 14C Offsets in the Southern Hemisphere?

    Hogg, Alan G.; Turney, Chris S.M.; Palmer, Jonathan G.; Cook, Ed; Buckley, Brendan (The University of Arizona, 2013)
    Center for Accelerator Mass Spectrometry (CAMS) Tasmanian huon pine (Lagarostrobos franklinii) decadal measurements for the interval AD 745–855 suggest a mean interhemispheric radiocarbon offset (20 ± 5 yr), which is ...
