Hualapai Mountain Tree-Ring Stable Isotope Archives

The data provided are the stable isotope ratios (d18O) of cellulose extracted from the wholewood of Ponderosa pine tree-rings. Sample material represents the years 1992-1998/2004 in two cores (A and B) from each of six trees, labelled HM2-HM7, from a stand located on a north facing slope of Hualapai Mountain, Kingman, Arizona. Cellulose was extracted using a modified SBrendel method (Evans and Schrag, 2004); Brookman and Whittaker, in press.
