How can the ratio of oxygen-18 and oxygen-16 be used as a “paleothermometer” / paleo-ice meter? Water with heavier oxygen isotopes (O18) requires less energy to evaporate than water with lighter oxygen isotopes (O16), and therefore gets enriched in ice sheets during cold periods. An explanation is given of the low O18-abundance in glacial waters. m. It produces effects in animals similar to those of tetrahydrocannabinol (THC), a cannabinoid naturally present in cannabis,. 1.
