International Stable Isotope Society

The International Stable Isotope Society (ISIS) is a global organization dedicated to advancing the scientific study of stable isotopes—non-radioactive forms of elements—in various natural and human-made systems. It brings together researchers from fields like geology, biology, environmental science, and archaeology to share knowledge, develop new methods, and promote the use of isotope analysis to understand Earth's processes, climate change, food sources, and more. ISIS organizes conferences, publishes research, and supports collaboration, helping scientists use isotope data to solve complex questions about our planet and its history.
