SEA—departures of actual (larger than average growth rings) from 1,000 simulated events based on bristlecone pine frost rings from the full 1,979-year Bronze–Iron Age juniper chronology (17) and now placed in time relative to a 745 BC end date for the Gordion sequence (which is a subset of the full chronology). Dashed lines represent 95% confidence limits. In the 745 BC position, a significant (P < 0.05) positive growth response in the Mediterranean trees shows the year after frost rings (eruptions).
