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

Journal 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.

Dating the penultimate great earthquake in south-central Alaska using tree-ring crossdating and radiocarbon wiggle-matching

Quaternary Science Advances

Radiocarbon Wiggle Matching on Laminated Sediments Delivers High-Precision Chronologies

Radiocarbon, 2018
ABSTRACTHigh-resolution sediment chronologies with the best possible time control are essential for comparing palaeoecological studies with independent high-precision climatic, archaeological or historic data in order to disentangle causes and effects of past environmental, ecological and societal change.

Radiocarbon Wiggle-Match Dating in the Intertidal Zone [PDF]

The Journal of Island and Coastal Archaeology, 2017
Radiocarbon wiggle-match dating is a technique that can combine the versatility of radiocarbon dating with chronological information from tree-rings. This makes it useful in contexts where timbers are preserved, but dendrochronological dating is impossible.

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

Radiocarbon, 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.

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

MethodsX, 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

A wiggle-match date for Polynesian settlement of New Zealand [PDF]

Antiquity, 2003
Dating initial colonisation and environmental impacts by Polynesians in New Zealand is controversial. A key horizon is provided by the Kaharoa Tephra, deposited from an eruption of Mt Tarawera, because just underneath this layer are the first signs of forest clearance which imply human settlement.

Synchronizing the Greenland ice core and radiocarbon timescales over the Holocene – Bayesian wiggle-matching of cosmogenic radionuclide records [PDF]

Climate of the Past, 2016
Investigations of past climate dynamics rely on accurate and precise chronologies of the employed climate reconstructions. The radiocarbon dating calibration curve (IntCal13) and the Greenland ice core chronology (GICC05) represent two of the most widely

Chronologies for Recent Peat Deposits Using Wiggle-matched Radiocarbon Ages: Problems with Old Carbon Contamination [PDF]

, 2005
Dating sediments which have accumulated over the last few hundred years is critical to the calibration of longer-term paleoclimate records with instrumental climate data.
