The GeoRef database, produced by the American Geosciences Institute, is focused on comprehensive coverage of geoscience literature published worldwide. The content is indexed with geoscience terms from the GeoRef Thesaurus, and geolocation data (latitude/longitude) is also assigned, when applicable. GeoRef is the most in-depth A&I database available for geoscience literature and research. It helps researchers to address some of the most urgent environmental concerns, such as: Continuing need for natural resources including critical minerals and fossil fuels, critical shortages in clean water supplies, preparedness for natural disasters – earthquakes, tsunamis, and developing changes in climate.
