Marine oxygen isotopic record, paleontology,

Known as "heavy" oxygen--because its mass is approximately % more than the mass of Oxygenand having an abundance of around %, Oxygen can be used along with Oxygen to determine ancient climate. This is because the ratio of Oxygen to Oxygen in water changes with the climate (Herring, ).

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

Oxygen is made up of two isotopes: Oxygen - 16 (also known as 16O 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ18O Oxygen - 18 (aka 18O 8 protons + 10 neutrons; a “heavy” oxygen). 16 and 18 are atomic masses of isotopes 16O and 18O.

The Oxygen isotope has an extra two neutrons, for a total of 10 neutrons and 8 protons, compared to the 8 neutrons and 8 protons in a normal oxygen atom. The slighty greater mass of 18 O— percent more than 16 O—results in differentiation of the isotopes in the Earth’s atmosphere and hydrosphere.

Oxygen 18 dating. Oxygen isotope ratio cycle - Wikipedia

Oxygen (chemical symbol O) has three naturally occurring isotopes: 16 O, 17 O, and 18 O, where the 16, 17 and 18 refer to the atomic mass. The most abundant is 16 O, with a small percentage of 18 O and an even smaller percentage of 17 O. Oxygen isotope analysis considers only the ratio of 18 O to 16 O present in a sample.

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.

14 C dating of organic debris under the ice block indicates commencement after Oxygen is fractionated from oxygen in the ocean-atmosphere system during evaporation, with the vapor preferentially enriched in 16 O. Fractionation of these isotopes also decreases with increasing temperature and salinity.

Ice Core Analysis

Light oxygen in water (H 2 16 O) evaporates more readily that water with heavy oxygen (H 2 18 O). Hence oceans will be relatively rich in 18 O when glaciers grow and hold the precipitated 16 O.
