Derivation and Analysis of Climatic Information from Tree Rings
chercheur principal: Jacoby, Gordon C.
Année(s) de permis: 1994 1989
Résumé: The researcher will take 5 mm diameter increment core samples from old-aged trees growing near the tree line. This sampling is not harmful to the trees. At two sites the researcher will sample about 10 trees. The samples are processed to produce ring-width and wood- density data for each annual ring. This data will then be statistically compared to meteorological data to make estimates of past cl...
