Wiggle-Match Dating of Tree-Ring Sequences [PDF]

open access: yesRadiocarbon, 2004
Given the non-monotonic form of the radiocarbon calibration curve, the precision of single 14C dates on the calendar timescale will always be limited. One way around this limitation is through comparison of time-series, which should exhibit the same irregular patterning as the calibration curve.

Dendrokronologija in absolutno datiranje kolišč na Ljubljanskem barju

open access: yesLes, 2022
Na 16 koliščih na Ljubljanskem barju v Sloveniji je bilo med leti 1995 in 2021 z arheološkimi izkopavanji zbranih več kot 8.800 vzorcev z vodo napojenega arheološkega lesa. Večina vzorcev je bilo odvzetih iz pilotov, zabitih v zemljo, na katerih so bila

Wood analyses helped to determine the location and approximate construction period of the Roman bridge over the Drava River in ancient Poetovio (Ptuj, Slovenia)

open access: yesLes, 2021
We present the results of a dendrochronological study and radiocarbon dating of the wooden piles of the bridge over the Drava River in Ptuj. The piles, together with stone elements (a fragment of an imperial building inscription and parts of the ...

Carbon‐14 wiggle‐match dating of peat deposits: advantages and limitations [PDF]

open access: yesJournal of Quaternary Science, 2004
AbstractCarbon‐14 wiggle‐match dating (WMD) of peat deposits uses the non‐linear relationship between 14C age and calendar age to match the shape of a series of closely spaced peat 14C dates with the 14C calibration curve. The method of WMD is discussed, and its advantages and limitations are compared with calibration of individual dates.

Bayesian evaluation of the southern hemisphere radiocarbon offset during the holocene [PDF]

open access: yes, 2009
While an interhemispheric offset in atmospheric radiocarbon levels from AD 1950–950 is now well established, its existence earlier in the Holocene is less clear, with some studies reporting globally uniform 14C levels while others finding Southern ...

Dating old hollow trees by applying a multistep tree-ring and radiocarbon procedure to trunk and exposed roots

open access: yesMethodsX, 2018
In the process of dating the oldest trees, which are often hollow, we developed a new method that combines tree-ring cross dating and wiggle matching radiocarbon techniques on wood samples extracted from the stem and from exposed roots. The method can be

Revised calendar date for the Taupo eruption derived by ¹⁴C wiggle-matching using a New Zealand kauri ¹⁴C calibration data set [PDF]

open access: yes, 2011
Taupo volcano in central North Island, New Zealand, is the most frequently active and productive rhyolite volcano on Earth. Its latest explosive activity about 1800 years ago generated the spectacular Taupo eruption, the most violent eruption known in ...
