  • Fractionation mechanism of stable isotope in evaporating water body
  • China ; Evaporation ; Isotope analysis ; Lake ; Moisture ; Simulation ; Temperature ; Tibet ; Water cycle
  • This study quantificationally analyses the interaction between evaporating water body and atmosphere, and the influences of different factors on the evaporation by probing into the fractionation mechanism of stable isotope as water body is vaporized

  • The area of investigation is the Sungai Niah basin in north-central Sarawak in the northern part of the island of Borneo. This paper reports results from a limited time period, to broadly understand the modern stable isotope processes of the Sungai
  • Niah basin. These stable isotope proxies have the potential to derive a high-resolution terrestrial Quaternary paleoclimatic reconstruction, currently lacking for Borneo. This paper therefore provides an essential first step in characterizing the modern
  • isotopic hydrological regime prior to reconstructing Quaternary environments from the isotopic proxies of the Great Cave of Niah.

  • The AA. analyzed oxygen isotopes in sediment cores from Jellybean Lake, located in the southern Yukon interior, to improve the detail and resolution of the regional climatic history and investigate mechanisms for Holocene climatic change. Holocene
  • changes in North Pacific atmospheric circulation inferred from Jellybean Lake oxygen isotopes correspond with late Holocene glacial advances in the St. Elias Mountains, changes in North Pacific salmon abundance, and shifts in atmospheric circulation over

  • The AA. present measurements of variations in the carbon and oxygen isotope compositions of shells of modern land snails from the southern Great Plains of North America : 12 localities in a narrow east-west corridor that extend from the Flint Hills
  • in North Central Oklahoma to the foothills of the Sangre de Cristo Mountains in Northern New Mexico, USA. The data are discussed in terms of their relationship to modern environmental variables to examine the likelihood that isotopic data from ancient land
