The International Union of Soil Sciences (IUSS), founded in 1924 under the name International Society of Soil Science, is a scientific union and member of the International Science Council (ISC).
Earth's critical zone is the “heterogeneous, near surface environment in which complex interactions involving rock, soil, water, air, and living organisms regulate the natural habitat and determine the availability of life-sustaining resources”. The Critical Zone, surface and near-surface environment, sustains nearly all terrestrial life.
The Geochemical Society is a nonprofit scientific organization founded to encourage the application of chemistry to solve problems involving geology and cosmology. The society promotes understanding of geochemistry through the annual Goldschmidt Conference, publication of a peer-reviewed journal and electronic newsletter, awards programs recognizing significant accomplishments in the field, and student development programs. The society's offices are located on the campus of the Carnegie Institution for Science in Washington, DC.

Susan L. Brantley is an American geologist and geochemist who is the Dr. Hubert Barnes and Dr. Mary Barnes Professor at Pennsylvania State University. Her research dominantly studies interactions between fluids and minerals at low temperatures, biological reactions in water-rich fluids within soils, and the geochemical processes that convert rock into soil. However, among many other topics, she has also published work on carbon dioxide emissions from volcanoes, and the environmental impact of shale gas extraction and nuclear waste disposal. During her career, Brantley has published over 200 research papers and book chapters, has been awarded academic prizes and fellowships by many of the world's leading geoscience societies, and has been described as "one of the leading aqueous geochemists of her generation."
Aradhna Tripati is an American geoscientist, climate scientist, and advocate for diversity.
