Multiple stable isotopes from oak trees in southwestern Scotland and the potential for stable isotope dendroclimatology in maritime climatic regions

An actively growing stalagmite collected from a cave located in the hills of the Western Ghats in the Uttar Kannada District of Karnataka, India, has been studied for stable isotope ratios of oxygen and carbon, width of growth layers and grey-level changes. Distinct carbonate layers, alternate coarse and compact, are seen in cross-section. Each couplet of compact and coarse layer is found to represent a single year. A total of 331 such couplets has been counted, indicating that the stalagmite started growing in AD 1666 and continued until it was sampled. Stable isotope ratios of oxygen (I´18O) and carbon (I´13C) show variations ranging from -13.6 to -7.9° and from -2.7 to 1.6°, respectively. We have reconstructed past rainfall changes of the cave site using the 'amount effect' in I´18O of rain. Speleothem I´18O and instrumental rainfall data from the associated climate subdivision show a significant correlation (r = -0.62, decadal average). Several sharp spikes of enrichment and depletion in 18O are indicative of the past deficiency and excess in rainfall. Most of the severe drought years recorded independently by meteorological observations are found registered in the stalagmite layers. During the 331-year-period, rainfall was highest at AD 1666 and lowest around AD 1900. The stalagmite-generated past rainfall record can serve as a reasonable proxy for testing monsoon models.

This monograph details the theoretical background of stable isotope fractionation in natural physico-chemical processes involving fresh water, the isotopic differences actually encountered in natural waters, and their use for practical hydrological purposes. The techniques for measuring D/H and /sup 18/O//sup 16/O ratios in water are discussed. (ACR)
