Biogeosciences is a relatively new section of the American Geophysical Union. Biogeoscienes was formed because of the recognized need to integrate the key role played by biology into the scientific study of the Earth and other planets. The goal in integrating biological sciences into AGU was to allow the AGU community to better address the interaction of humans with climate, hydrology, and ecosystems.
