On the other hand, dendrochronology was applied to four paintings depicting the same subject, that of Christ expelling the money-lenders from the Temple.The results showed that the age of the wood was too late for any of them to have been painted by Hieronymus Bosch.The most recent publication of the atmospheric calibration curve is INTCAL09 (Reimer et al., 2009) which superceded the previous dataset, INTCAL04 (Reimer et al., 2004)."C production as measured from tree rings coincide with the periods of highest cooling during the past 1200 years.In 1859, the German-American Jacob Kuechler (1823–1893) used crossdating to examine oaks (Quercus stellata) in order to study the record of climate in western Texas.A new layer of wood added in each growing season, thickening the stem, existing branches and roots, to form a growth ring.The outer portion is the "late wood" and has sometimes been termed "summer wood", often being produced in the summer, though sometimes in the autumn and is denser.
Upper and lower coordinates show reconstructed time tables. Roman lead covered box with Roman glass urn (100-120 CE) from Mersea’s Roman barrow. "The Strood causeway to Mersea Island was thought to be Roman, built in the 1st c. It leads to Mersea’s Roman burial mound (barrow) where a typical Roman lead covered box with a no less typical Roman glass urn (tentatively dated between 100 and 120 AD) was retrieved [in the image on the right].
AD to reach their settlements on the Island." "Scientific dating methods have been applied to some substantial oak piles discovered beneath the Strood in 1978, when a water-main was being laid. The piles were discovered at the south end of the causeway where the trench was at its deepest—they were about 1.6m below the present ground level and were sealed by a series of road surfaces.
They indicate that the structure was probably built between A. Seven piles were recovered and samples were submitted to Harwell laboratory for radiocarbon dating to get a rough idea of the date.
An additional sample from another beam yielded a date of 1641, thus confirming the house had been constructed starting in 1638 and finished sometime after 1641 as wood was not seasoned before use in building at that time in New England.
"Tree ring studies from the last two centuries show that the radiocarbon activity in wood grown in AD 1950 (before nuclear weapons testing) is lower than in samples grown in AD 1850 (prior to the internationally accepted boom in fossil fuel combustion from the industrial revolution) despite the radioactive decay of 14C that has occurred in the latter (Aitken, 1990)." "Calibration using dendrochronologically dated, continuously overlapping tree-ring sequences has proven to be the most successful method since the production of the first calibration curves (Stuiver and Suess 1966, Suess 1979).
