Use the key-words: Ocean-Ice-sheet-results (curve) - seal level - temperature. Under cooler sea surface temperature conditions there will be a higher percentage of O18 in the seashells than under warmer conditions. Clonal relationships were defined by amplification phylotyping. 1 (PubChem release 2021. Please notify us of any errors or corrections in the above data. Because the atomic. O18 . 2. 2 Items . Molecular Weight 20. Oxygen ( O ) has three naturally occurring isotopes: O16, O17, and O18. Here, natural-abundance isotope quantifications of O2 yield mechanistically significant reaction kinetic isotope effects for water. The formation of a water molecule occurs from both the isotopes.
