Confidence ellipses are la and correspond to the modern reference equine fat values (Outram et al. 2009)...

In figure 12 we show oxygen and hydrogen isotope ratios in a Japanese Cryptomeria japonica, also from the island of Yaku at the southern tip of Japan as is the modern cedar (figure 9), for the years 137-1900 A.D., compared with temperatures deduced from old diaries for Japan and China. [Pg.267]

The importance of oxygen and hydrogen isotope ratios in the water cycle was first demonstrated by Dansgaard (1964), who showed that a simple linear relationship exists between < 180 in precipitation and the average annual air temperature. Through the isotopic analysis of a large number of meteoric water samples (rainfall and surface water) collected at different latitudes, Craig (1961) had previously demonstrated that a simple relationship existed between <5180 and < D in precipitation ... [Pg.171]

Stable oxygen and hydrogen isotopic ratios are normally reported relative to the standard mean ocean water (SMOW) standard (Craig, 1961b) or the equivalent Vienna-SMOW (V-SMOW) standard. Carbon, nitrogen, and sulfur stable isotope ratios are reported relative to the Pee Dee Belemnite (PDB) or Vienna-PDB (VPDB), ambient air (AIR), and Canyon Diablo Troilite (CDT) standards, respectively, as defined later. The use of the V before SMOW or PDB indicates that the measurements were calibrated on normalized per mil scales (Coplen, 1996). [Pg.2576]
