My mission was born from an overwhelming need among dendrochronologists for a permanent repository of information that was free to the public, easily understandable, and as comprehensive as humanly possible.
Come back and visit from time to time to learn more about new or updated software, new educational tools, new institutions conducting tree-ring research, new publications, and more!
Students can also infer similar information by using various wooden objects.
This Lab-Aid uses highly motivating, easily performed activities. Materials in this kit, designed for 30 students, are reusable.
Consequently, the calibration is a circular process and the tree ring chronology extension is also a circular process that is dependent on assumptions about the carbon dating system.
The extended tree ring chronologies are far from absolute, in spite of the popular hype.
It is clear that dendrochronology is not a clear-cut, objective dating method despite the extravagant claims of some of its advocates.I believe that a scientific discipline is only as efficient and important to society as the information available to it.
