Since the inadvertent discovery of multiple isotopes of Neon by J.J. Thomson in 1913, the measurement and study of stable isotopes has yielded a dizzying array of information about the world around us. From recording the growth and collapse of ice sheets, to tracing the rise of oxygen in Earth’s atmosphere, stable isotopes provide us with an archive of the invisible processes that have shaped Earth’s history. This talk will aim to give a brief introduction into the basics of stable isotopes: What are they? How do we measure them? What terminology do we use to talk about them? And most importantly, what are some hidden processes that we can use the to reveal?
