Stable Oxygen Isotopes & Paleoclimate Proxies | GEO GIRL

Stable oxygen isotopes- how oxygen isotope ratios can be tracked throughout different environmental systems and through geologic time due to predictable isotopic fractionation pathways to reconstruct Earth's history. Specifically, oxygen isotope basics, heavy versus light isotopes, oxygen 16, 17, and 18 relative abundances, isotope notation (permil notation), ocean and atmosphere temperature proxy, elevation proxy, paleoclimate / paleoenvironment proxy, carbonate fossils (foraminifera, mollusks, corals, sponges, coccolithophores), apatite (conodont, teeth fossils), ice cores, ice core climate / temperature reconstructions using oxygen, hydrogen, and carbon isotope composition, ice core bubbles, tree rings, leaf shapes, and more!
