Glaciologists, geochemists, and climatologists study ice layers to learn about past climates. Distinct ice layers are caused by variations in temperature and precipitation over time, as well as volcanic eruptions and other climatic events that deposit different materials within the ice. When studying ice layers, scientists use advanced analytical techniques such as mass spectrometry to measure isotopes of certain gases trapped within the ice. These gases reveal the atmospheric composition and temperature at the time when the ice layers were formed, providing crucial insights into the Earth's climate history.
