Wiggle matching, also known as carbon–14 wiggle-match dating (WMD) is a dating method that uses the non-linear relationship between 14 C age and calendar age to match the shape of a series of closely sequentially spaced 14 C dates with the 14 C calibration curve.
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby.
It was founded in 1959 as a supplement to the American Journal of Science, and is an important source of data and information about radiocarbon dating. It publishes many radiocarbon results, and since 1979 it has published the proceedings of the international conferences on radiocarbon dating. [1] The journal is published six times per year.
C in the sample at the time the tree ring was formed – and hence the 14 C / 12 C ratio in the atmosphere at that time. [1] Armed with the results of carbon-dating the tree rings, it became possible to construct calibration curves designed to correct the errors caused by the variation over time in the 14 C / 12 C ratio.

Two common contaminants are humic acid, which can be removed with an alkali wash, and carbonates, which can be removed with an acid.These treatments can damage the structural integrity of the sample and remove significant volumes of material, so the exact treatment decided on will depend on the sample size and the amount of carbon needed for the chosen measurement technique.

The marine reservoir effect is a phenomenon affecting radiocarbon dating.Because much of the carbon consumed by organisms in the ocean is older than that consumed by organisms on land, samples from marine life and from organisms that consumed a lot of sea-based foods while alive may appear older when tested than they truly are.
