WebThe isotopic composition of the oceans has proved to be related to the storage of water in large ice sheets on land. Because molecules of oxygen-18 evaporate less readily and condense more readily, an air mass with oceanic water vapour becomes depleted in the heavier isotope (oxygen-18) as the air mass is cooled and loses water by precipitation. WebMeasurements of the isotopes of hydrogen and oxygen of water from ice cores provide important records of past climate ( Dansgaard, 1964 ). Both δ D and δ18 O have long been used as proxies for temperature ( Jouzel et al., 1997 ).

WebJan 2, 2024 · The ice cores are examined in laboratories with a series of analyses that reveal past climate. The content of the heavy oxygen isotope O 18 in the ice cores tells us about the temperature in clouds when the snow fell, and thus of the climate of the past. The air bubbles in the ice are also examined.
