"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. " - H2 18o
