How are past temperatures determined from an ice core? - Scientific American

In the following, dating using oxygen isotope data (δ 18 O) is described, although exactly the same techniques can be applied when using hydrogen isotope data (δD). The annual cycle in δ 18 O is connected to local or regional temperature variations and is a very reliable indicator of the seasonal temperature cycle.

Oxygen Oxygen is an isotope of oxygen, frequently used in positron emission tomography, or PET imaging. It can be used, amongst other applications, in water for PET myocardial perfusion imaging and for brain imaging. It has 8 protons, 7 neutrons, and 8 electrons. The total atomic mass is Standard atomic weight (A): [, ], Conventional:

The dominant oxygen isotope is 16O, meaning it has 8 protons and 8 neutrons, but 18O, an isotope with 10 neutrons, also exists. By discovering the ratio of 16O to 18O in a fossil, scientists can obtain a reasonable estimate for the temperature at the time the organism existed.

Marine oxygen isotopic record, paleontology,

Carbon dating is a common radioactive isotope test performed on organic substances. In Quaternary studies, however, scientists have found stable isotopes (i.e. those that do not decay) much more useful. Because oxygen can be found principally in two stable varieties, it stands to reason that some water molecules will contain Oxygen atoms.
