Tree ring and carbon 14 dating dating depressed person

Most people who enter into studying tree rings typically come from one of several disciplines: Though dendrochronology also has uses for art historians, medieval studies graduates, classicists, ancient and historians due to the necessity to date some of the materials that the fields will be handling in their research projects.Typically, a bachelor's degree in any of the above disciplines are enough to study the data that comes out of dendrochronology.We can date organic archaeological material and create a chronological record against which artefacts can be dated (3).

Wood helps the developing tree to stay strong as it gets older and grows upwards, building new branches and drinking in more sunlight for photosynthesis reproduction.American Astronomre A E Douglass, who had a strong interest in studying the climate, developed the method around 1900 (4).He theorised that tree rings could be used as proxy data to extend climate study back further than had previously been permissible.This enormous and comprehensive data set is fundamental to both European and North American studies of the palaeoclimate and prehistory (8).There is one major drawback to dendrochronology and that is that we can only date the rings in the tree.
