dc.description.abstract | Closely spaced sequences of accelerator mass spectrometer (AMS) 14C dates of peat deposits display century-scale wiggles which can be fitted to the radiocarbon calibration curve. By wiggle-matching such sequences, high-precision calendar age chronologies can be generated which show that changes in mire surface wetness during the Bronze Age/Iron Age transition (c. 850 cal. bc) and the ‘Little Ice Age’ (Wolf, Spörer, Maunder and Dalton Minima) occurred during periods of suddenly increasing atmospheric concentration of 14C. Replicate evidence from peat-based proxy climate indicators in northwest Europe suggest these changes in climate may have been driven by temporary declines of solar activity. Carbon-accumulation rates of two raised peat bogs in the UK and Denmark record low values during the ‘Little Ice Age’ which reflects reduced primary productivity of the peat-forming vegetation during these periods of climatic deterioration. | |
