Wiggle-Match Dating of Tree-Ring Sequences

Wiggle-match dating was applied to bulk sediments to evaluate the possibility of constructing accurate chronologies in the absence of terrestrial plant macrofossils and when the amount of old carbon in the sediments is unknown. Facilitated by a floating varve chronology and relatively stable 14C reservoir ages, the results show the possibility to assess the contribution of old carbon solely based on the 14C wiggle-matching of bulk sediments. We confirm the wiggle-matched chronology and the 14C reservoir age of approximately yr by cross-checking the results with 14C dating of macrofossils. The obtained calibrated ages based on bulk sediments have an uncertainty range of about 60—65 yr This study confirms that 14C wiggle-match dating of bulk sediments is a viable tool when constructing high-resolution chronologies. The method is especially useful in Sun-climate studies since the timing between solar activity variations expressed as 14C variations and climate changes can be accurately determined.

Blaauw, B. Van Geel, Dmitri Mauquoy , J. Carbon wiggle-match dating WMD of peat deposits uses the non-linear relationship between C age and calendar age to match the shape of a series of closely spaced peat C dates with the C calibration curve. The method of WMD is discussed, and its advantages and limitations are compared with calibration of individual dates. During several intervals of the Holocene, the C calibration curve shows less pronounced fluctuations. We assess whether wiggle-matching is also a feasible strategy for these parts of the C calibration curve.

T1 – Validation of wiggle matching using a multi-proxy approach and its paleoclimatic significance. N2 – Research into global, millennial-scale climate oscillations during the last glacial requires wiggle matching. One method for adequate wiggle matching is based on the dating of the climate proxy records.

Luminescence dating methods are needed for estimates of last glacial ages in terrestrial records. However, such dating methods are not accurate enough for millennial-scale wiggle matching. It is shown that a multi-proxy comparison of two sections that are situated close to each other may considerably improve the accuracy of wiggle matching. The method is tested by an application on two loess sections of last glacial age in Vojvodina, Serbia. Firstly, single proxy-wiggle matches between both sections are analysed successively with the same and with different proxies.

Secondly, a multi-proxy wiggle match based on all three proxies of the two sections is presented and compared to the single-proxy tests.

The problem of insufficient age-control limits the utilisation of the 8. High-resolution radiocarbon dates, magnetic susceptibility and lithostratigraphic evidence from a lake sediment core from Nedre Hervavatnet located at Sygnefjell in western Norway provide a record of the early Holocene. We use the method of radiocarbon wiggle-match dating of the lake sediments using the non-linear relationship between the C calibration curve and the consecutive accumulation order of the sample series in order to build a high-resolution age-model.

The timing and duration of Holocene environmental changes is estimated using 38 AMS radiocarbon dates on terrestrial macrofossils, insects and chironomids covering the time period from to cal BP. Chironomids, Salix and Betula leaves produce the most consistent results.

Here we show that previous work using tree-ring dating to place these timbers We carried out a program of tree-ringC-wiggle-matching on.

This paper aims to present the method used, not often performed within the Danish field of archaeology, and to discuss the result and the prospects it provides for medieval and renaissance archaeology, in situations where there is an absence of dateable dendro-samples or for dating of non-oak samples combined with dendrochronological dating. Having unearthed the rampart remains, a major objective of the excavation became answering the question: Are the ramparts found those that were built during the short Swedish occupation of the town in ?

And could the C14 dating method provide us with a sufficient level of precision to answer this question? The results turned out to be much more complicated. They show us that the ramparts found belonged to the medieval fortification of the town and have a long history of renewal and repair, allowing us to map the long life of the town despite the limitations of the small ‘key-hole’ style excavations. Applying this method more extensively on small-wood remains in forthcoming excavations will perhaps help us to finally identify that elusive Swedishfortification.

AD and European arrival in New Zealand. Radiocarbon wiggle-match dating refers to the fitting of several 14 C data points of unknown calendar age from a constrained sequence e. Matching of the data to the wiggles in the curve significantly improves the precision of the calibration, and also reduces the influence of minor offsets which can result in a wide spread in calibrated age. A miro post was sampled for tree-ring analysis and 14 C AMS dating. Wiggle-match results comprising the two innermost and two outermost 5-ring dates are given in Table 2.

If this result can be repeated on other sites, and if there is comparably detailed analysis of relevant oral traditions, then for the first time in New Zealand we might be able to write a rich material and social history of a region in the period before European observation.

This chapter discusses the principles of radiocarbon dating; sample selection; contamination; calibration; Bayesian mathematics; wiggle-match dating WMD ; and dating wetland archaeology using WMD. Radiocarbon is the most frequently applied tool for dating the prehistoric past. Much research has been undertaken in understanding and removing the effects of contamination in the samples used in the dating process. For wetland sites, there is great potential for obtaining high-resolution dates where dendrochronological dating is problematic for various reasons.

Using Bayesian statistical approaches, WMD on suitable samples can utilize the wiggles in the calibration curve to great advantage and determine ages that can be highly precise.

Jacobsson, P. Journal of Island and Coastal Archaeology , 14 1 , pp. 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. As intertidal and marine timbers are waterlogged, this can favor their preservation and hence allow wiggle-match 14C dating, which can be of significant help in deriving relatively precise chronologies for a range of coastal structures.

As the technique depends on making multiple radiocarbon measurements towards a single date, efficiency in application is the key and hence a number of practical considerations need to be taken into account in advance of conducting a dating program.
