Why was atomic mass scale changed from Oxygen - 16 to Carbon

WebApr 6, 2024 · Isotopes of elements are designated by their mass number. Oxygen atoms with a mass number of 16 are called oxygen-16, or O-16, while oxygen atoms with a mass number of 17 are called oxygen-17, or O-17, and oxygen atoms with a mass number of 18 are called oxygen-18, or O-18. In geochemistry, paleoclimatology and paleoceanography δ O or delta-O-18 is a measure of the ratio of stable isotopes oxygen-18 ( O) and oxygen-16 ( O). It is commonly used as a measure of the temperature of precipitation, as a measure of groundwater/mineral interactions, and as an indicator of processes that show isotopic fractionation, like methanogenesis. In paleosciences, O: O data from corals, foraminifera and ice cores are used as a proxy for temperature. chimney rock nc stairs
