The field of dendrochronology had a developmental "head start" of at least several decades relative to the inception of radiocarbon dating in the late 1940s, but that evolution was sufficiently advanced so that unique capabilities of tree-ring science could assure success of the 14C enterprise.The Laboratory of Tree-Ring Research (LTRR) at the University of Arizona played a central role in the cross-pollination of these disciplines by providing the first wood samples of exactly known age for the early testing and establishment of the "Curve of Knowns" by Willard Libby.In 2007 Fiona Petchey visited the Keck Radiocarbon laboratory in Irvine, California and worked closely with Dr. Since 1980 we have run over 37000 radiometric and AMS samples.During this time the popularity of AMS has grown from only 4% of our total throughput in 1996, to around 80% in 2015.Radiocarbon dating Organic matter contains a certain amount of carbon-14, a radioactive isotope of carbon (under normal conditions carbon has an atomic weight of 12).Carbon-14 (14C ) is unstable, and degrades exponentially over time. The Waikato Radiocarbon Dating Laboratory was established in 1974 by Prof.Alex Wilson in anticipation of geomorphology and tephrostratigraphy projects looking at landform processes in the Waikato region.

Details Calibration of a radiocarbon age of 6550 ± 40 BP of a terrestrial sample from the Northern Hemisphere, using Int Cal04 calibration curve and Ox Cal program version 3.10.

All organisms have a certain amount of 14C present in their bodies – it is absorbed out of the atmosphere by plants during the process of photosynthesis, and transferred to animals when the plants are eaten.

While alive, organisms experience a balance of 14C intake and dissipation.

Our reports contain official radiocarbon dating certificates for each sample together with calibration curves showing how each conventional radiocarbon age for samples has been calibrated with the calendar year curve.

Suitable for dating sediments up to c.45Ka old as long as they contain suitable biogenic material (molluscs, microfossils, wood).Careful sample preparation by Strata Data is matched by the world class analysis by Beta Analytic Inc.
