Clues
- A technique that ensures each individual tree ring is assigned its exact year of formation. This is achieved by matching patterns of wide and narrow rings between cores from the same tree, and between trees from different locations. (5, 6)
- An example of an incremental dating technique, based on annual incremental growth - in this case "cones" of wood added, which in a cross-section through a tree-trunk look like a barcode of thick and thin annual layers (16)
- Dating of individual tree-rings from master chronologies allows radiocarbon "age" to be compared to what timescale? (11, 9)
- In which type of climate do thick rings represent humid summers? (3, 8)
- In which type of climate do thick rings represent warm summers? (4, 8)
- What are long, cross-matched series where the tree ring signature is linked to a living tree. (6, 10)
- What can be converted to temperature or precipitation indices using transfer functions based on growth/climate relationships known from living trees (4, 6)
- What method can be used to date individual rings? (3, 6)
- When a tree ring signature is not linked to a living tree. (8, 10)
