Chronology
Recent work has produced data that suggest that these models may be incorrect, and that unusually high levels of radiocarbon production could perhaps lead to ages that are more than one half-life too young (Voelker et al., 2000; Beck et al., 2001; Conard and Bolus, 2003; Giaccio et al., 2006; Nadeau...

| Summary: | Recent work has produced data that suggest that these models may be incorrect, and that unusually high levels of radiocarbon production could perhaps lead to ages that are more than one half-life too young (Voelker et al., 2000; Beck et al., 2001; Conard and Bolus, 2003; Giaccio et al., 2006; Nadeau et al., 2006). Giaccio et al.’s both taxa greater than it actually was (Conard and Bolus, 2003). The amplitudes of late Pleistocene production peaks remain highly controversial. The peaks in the speleothem data from the Bahamas have been reduced by newmodels for accounting for dead carbon and by using smoothing functions to reduce the amplitude of peaks and bring them in line with data from the Cariaco Basin and other marine archives (Hughen et al., 2006; Richards et al., 2006). The irregularities in the North Atlantic data of Voelker et al. (2000) have been largely dismissed as a result of stochastic noise * Corresponding author. Contents lists availab m.e l |
