Within the realm of the newly evolving discipline of environmental sciences, the stable-isotope methodology is being used to an ever-increasing extent, especially in the study of the water cycle and of paleo-climatology. This book introduces the rule

Surface waters which are exposed to the atmosphere are one of the most widely studied systems and thus can be used as a model to understand the rules of the game involved in the isotopic changes imposed by the hydrologic pathways. Direct evaporation

Attempts to explain the variations in the abundance of heavy isotopic species of water throughout the hydrologic cycle solely by means of the classical equilibrium-fractionation processes could not be reconciled with measured abundances of the isotop

A survey of the stable isotope content of tissue waters of plants from the Negev desert was conducted. Large differences were observed in the extent of enrichment of the heavy isotopes in leaf water relative to local precipitation among different pla

At and near the land surface, the precipitation is partitioned into fluxes of percolation, surface runoff and evapo-transpiration. These processes are accompanied by changes in the stable isotopic composition, primarily the result of isotopic fractio

The stable isotope content of samples of precipitation and of the river water throughout the Piracicaba basin in Brazil was measured over a two-year period. The isotope values of precipitation follow a consistent pattern of relatively depleted values

A lake, as a body of water, is in continuous interaction with the rocks and soils in its drainage basin, the atmosphere, and surface and groundwaters. Human industrial and agricultural activities introduce new inputs and processes into lake systems.

▪ Abstract Changes of the isotopic composition of water within the water cycle provide a recognizable signature, relating such water to the different phases of the cycle. The isotope fractionations that accompany the evaporation from the ocean and

Waters of the eastern Mediterranean portray an unusual pattern of stable isotope composition compared with other evaporitic systems: an increase in 18O concentration up to value of δ18O = +2.2‰ is not matched by a commensurate increase of deuteriu

The isotopic ratios 13 C 12 C and 18 O 16 O of cellulose from tamarix trees which were used by the Roman army as a groundwork of the siege-rampart of Masada ( ad 70–73) were compared with ratios measured in present-day tamarix trees growing in the
