Oxygen and Hydrogen Isotopes in the Hydrologic Cycle
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 other surface waters and the reverse process of rain formation account for the most notable changes. As a result, meteoric waters are depleted in the heavy isot...
متن کاملOxygen Isotopes in Meteorites
Oxygen isotope abundance variations in meteorites are very useful in elucidating chemical and physical processes that occurred during the formation of the solar system (Clayton, 1993). On Earth, the mean abundances of the three stable isotopes are O: 99.76%, O: 0.039%, and O: 0.202%. It is conventional to express variations in abundances of the isotopes in terms of isotopic ratios, relative to ...
متن کاملShort-term variation of triple oxygen isotopes and gross oxygen production in the Sagami Bay, central Japan
We studied diurnal and daily variations in triple oxygen isotopes in the euphotic zone of the Sagami Bay during summer 2003 and 2004. There were sharp changes in physical processes, driven by changes in wind speeds, during the study period. Mixed-layer 17D anomalies were negatively correlated with wind speeds, whereas dissolved oxygen (DO) and chlorophyll a (Chl a) were positively correlated, s...
متن کاملSpace Observations of Water Isotopes Provide a New Tool for Understanding the Water Cycle
Workshop/Meeting Summaries: – First NEESPI Summit 13 – GABLS Workshop 14 More depleted values of δD shown at the higher latitudes indicate a long history of condensation during transit from a lower latitude source, while less depleted values in the tropics reflect ventilation of recently evaporated boundary layer vapor into the free troposphere (above 850 hPa, where TES is sensitive). Knowledge...
متن کاملOxygen Isotopes in Chondritic Interplanetary
Introduction: Planetary objects have preserved various amounts of oxygen derived from isotopically distinct reservoirs reflecting their origins and diverse physico-chemical histories [1]. An O-rich component is preserved in high temperature phases, such as refractory inclusions (CAIs) and some chondrules, whereas meteorite matrices are enriched in a relatively O-poor component [2]. The origin o...
