Differential Hydrogen Isotopic Ratios of Sphagnum and Vascular Plant Biomarkers in Ombrotrophic Peatlands as a Quantitative Proxy for Precipitation-Evaporation Balance
Author(s):Nichols, J.; Booth, R. K.; Jackson, Stephen T.; Pendall, Elise; Huang, Y. S.; Nichols, J.; Booth, R. K.; Jackson, Stephen T.; Pendall, Elise; Huang, Y. S.
We have developed a new approach to quantitatively reconstruct past changes in evaporation based on compound-specific hydrogen isotope ratios of vascular plant and Sphagnum biomarkers in ombrotrophic peatland sediments. ...
Patterns and Sources of Multidecadal Oscillations in Drought-Sensitive Tree-Ring Records from the Central and Southern Rocky Mountains
Author(s):Gray, S. T.; Betancourt, J. L.; Fastie, C. L.; Jackson, Stephen T.; Gray, S. T.; Betancourt, J. L.; Fastie, C. L.; Jackson, Stephen T.
Tree-ring records spanning the past seven centuries from the central and southern Rocky Mountains were studied using wavelet analysis to examine multidecadal (>30-70 yr) patterns of drought variation. Fifteen tree-ring ...
