Carbon Dating - Dendrochronology As we've already seen, in order for Carbon dating to work we need to know what the C to C ratio was at the time of a specimen's death. If the ratio has fluctuated throughout the unobservable past and we can be sure that it has , how can we determine what the ratio was during the lifetime of a specimen that lived and died before we first began measuring the ratio? Advocates of the Carbon dating method have turned to "Dendrochronology" a. By carbon dating a piece of wood which has also been dated by counting its annual tree-rings, scientists can create a table by which they can convert the questionable Carbon years into true calendar years. This is how it works: scientists begin with a living tree or dead wood specimen which can be accurately dated by some reliable means.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word "absolute" implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geology , the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on Earth.
The ancient eruption of Thera on the Greek island of Santorini has long been a font for popular flights of fancy. While these theories do not currently get much mileage in academic circles, the allure and mystery of the very real eruption of Thera is abiding among scholars attempting to pinpoint its actual occurrence. Now, a University of Arizona study on carbon dating methodology could catalyze a shift in the timeline for ancient Mediterranean chronology, and potentially set a firm date for the natural disaster. Charlotte Pearson attempts to use high-resolution radiocarbon dating methods to firm up the Thera blast, one of the most elusively undated events of the ancient world.
