More recently, however, the types of records available for calibration have diversified and a large group of scientists (known as the Int Cal Working Group---IWG) with a wide range of backgrounds has come together to create internationally-agreed estimates of the calibration curves.In 2002, Caitlin Buck was recruited to the IWG and asked to offer advice on statistical methods for curve construction.You may now see our list and photos of women who are in your area and meet your preferences.Again, please keep their identity a secret Click on the "Continue" button search with your zip/postal code.

This paper reports on that work and on the on-going work that will eventually provide models, methods and software for rolling updates to the curve estimates.

Willard Libby, the inventor of radiocarbon dating, pointed out as early as 1955 the possibility that the ratio might have varied over time.

Discrepancies began to be noted between measured ages and known historical dates for artefacts, and it became clear that a correction would need to be applied to radiocarbon ages to obtain calendar dates. As of 2017 this is the most recent version of the standard calibration curve.

It was unclear for some time whether the wiggles were real or not, but they are now well-established.

These were superseded by the INTCAL series of curves, beginning with INTCAL98, published in 1998, and updated in 2004, 2009, and, most recently, 2013.
