PROBLEM SOLVING ACTIVITY: READING BETWEEN E RINGS One way scientists are learning about past climate is by studying tree-rings. is field of research is known as dendrochronology. Scientists can use tree rings and cores to measure e age of a tree and learn more about e local climatic conditions e tree experienced during its lifetime. Following veriﬁcation of dating and measuring, tree-ring series are detrended. In particular, ring-wid series typically line from pi to bark in a negative exponential fashion due to a geometric constraint of tree grow whereby trees add about e same amount of biomass each year to eir. Time-Wid and e Old Wood Problem. e time-wid of an organism refers to its total grow and exchange period wi e biosphere. e time-wid affects e way radiocarbon age is converted into calendar age for a sample. A wood’s time-wid depends on e number of tree rings taken for radiocarbon dating. Fragments of charcoal, however. 25, · ese rings can tell us how old e tree is, and what e wea er was like during each year of e tree’s life. e light-colored rings represent wood at grew in e spring and early summer, while e dark rings represent wood at grew in e late summer and fall. One light ring plus one dark ring equals one year of e tree’s life.
