- Abstract
An increase in atmospheric radiocarbon (14C) content of about 11.3‰ in the period AD 993–994 was observed in annual tree rings from Japanese cedar (Cryptomeria japonica) and Hinoki cypress (Chamaecyparis obtusa) (Miyake et al. 2013, 2014). Single-year samples of dendrochronologically dated tree rings (English oak, Quercus robur) from Kujawy, a village near Krakow (SE Poland), spanning the years AD 981–1000, were collected, and their 14C content was measured using the AMS system in the Leibniz Laboratory. The results clearly show an increase of 6.2±1.6‰ in the 14C concentration in tree rings between AD 993 and 994, with a maximum increase of 10.9±1.7‰ between AD 991 and 994.
