  • Oxygen and hydrogen isotopes were measured in wood celullose and cellulose-nitrate from trees that grew in different hydrologic settings in southwestern Ontario. An isotope model that accounts for isotopic fractionations associated
  • with photosynthesis in plants was applied to the stable isotope data to infer past meteoric water isotopic composition and seasonal air moisture variations. The result is an account of summer and winter conditions in southwestern Ontario for 275 yyears (1610 to 1885

  • Aquifer ; Deuterium ; Great Basin ; Groundwater ; Isotope analysis ; Oxygen 18 ; Palaeohydrology ; Tritium ; United States of America
  • This study interprets relative groundwater ages, distinguishes vertical and lateral flow paths, and evaluates paleoclimatic implications of isotopic stratification of groundwater beneath the U.S. High Plains.

  • An oxygen-isotope paleothermometer from ice in siberian permafrost
  • The AA. propose to use oxygen isotope composition (δ18O) of ground ice (ice cement, as well as segregated ice) for reconstruction of cold-season paleotemperature (Tc) in permafrost areas. The term cold season refers to the period when precipitation
  • falls as snow. The mean isotopic composition of annual precipitation in polar regions is highly correlated with the mean annual air temperature near the ground surface and this robust correlation constitutes a solid basis for using ancient precipitation

  • This paper presents stable carbon and nitrogen isotope data obtained from the fossil bone collagen of late Pleistocene short-faced bears and brown bears, and bone collagen from modern brown bears in eastern Beringia. The data elucidate many
  • important aspects of these bears'diets and can be used to test the potential for competive interactions. The A. also summarizes a model of short-faced bear foraging behavior that is the most parsimonious integration of the isotope data and the morphological
