How many oxygen isotopes are there
Web11 feb. 2024 · Introduction to oxygen. The isotope used most often as a palaeothermometer is oxygen. Oxygen (O) has three stable isotopes: 16 O, 17 O, and 18 O. It is the ratio of 18 O to 16 O that is usually used in palaeoclimatological studies. The ratio of 18 O and 16 O in biomineralised elements (that is bones, shells and teeth) is … WebOxygen accounts for about 23% of the atmosphere's mass with pairs of oxygen atoms stuck together to make dioxygen molecules, but it's not just in the air, we breathe.

Before the industrial revolution, δ 13 C of our atmosphere was approximately -6.5‰; now the value is around -8‰. Recall that plants have less 13 C relative to the atmosphere (and therefore have a more negative δ 13 C value of around -25‰).
