The Dated Master Dendrochronology
What is a dated master dendrochronology? See figure at right:
- Constructed from previously crossdated samples
- Has calendar years, 1895 to 1926, in this case
- Time series of standardized growth indices
- Average of 1.0, normal growth
- Minimum of 0.0, below-average no growth
- Maximum of 2.0, above-average to great growth
- Marked as if it were a skeleton plot
- Small indices represented by long marks hanging down (e.g., 1919)
- Large indices represented by "b" marks (e.g., 1922 and 1926)
Good idea: To see how to make marks when skeleton plotting, look at the master chronology to see what values of ring growth merit a long mark versus no mark at all versus a "b" mark
