The modern and Last Glacial Maximum hydrological cycles of the Eastern Mediterranean and the Levant from a water isotope perspective
a r t i c l e i n f o a b s t r a c t The isotopic composition of precipitation (δ P) is one of the most widely used and informative terrestrial paleoclimate proxies. δ P integrates a series of hydrological processes; therefore, any interpretation of paleohydrology using δ P requires a thorough understanding and quantification of the full hydrological cycle. In this paper, we use modern data to...

Article history: Received 6 May 2015 Received in revised form 16 March 2016 Accepted 19 March 2016 Available online 21 March 2016 Many studies of Quaternary climatemake use of terrestrial stable isotope records which are interpreted based on seasonal patterns of stable isotopes in modern precipitation. Multi-decade records of isotopes in rainfall allow testing of the assumed behavior of isotope...

The application of stable isotopes in speleothem records requires an understanding of the extent to which speleothem calcite isotopic compositions refl ect the compositions of the cave waters from which they precipitate. To test for equilibrium precipitation, modern speleothem calcite was grown on glass plates, so that the carbon and oxygen isotope composition of the calcite and the water from ...

متن کاملSeasonality of westerly moisture transport in the East Asian summer monsoon and its implications for interpreting precipitation 18O
East Asian summer monsoon (EASM) rainfall impacts the world’s most populous regions. Accurate EASM rainfall prediction necessitates robust paleoclimate reconstructions from proxy data and quantitative linkage to modern climatic conditions. Many precisely dated oxygen isotope records from Chinese stalagmites have been interpreted as directly reflecting past EASM rainfall amount variability, but ...
