“The mission of GSA is to be a leader in advancing the geosciences, enhancing the professional growth of its members, and promoting the geosciences in the service of humankind.” The site provides access to information about the membership, publications and activities of the society, as well as links to other societies, agencies and organizations in the geological sciences.
The American Geophysical Union (AGU) is a worldwide scientific community that advances, through unselfish cooperation in research, the understanding of Earth and space for the benefit of humanity. This site contains information about the publications and activities of the society.
Founded in 1917 and currently the world’s largest professional geological society with more than 30,000 members, the American Association of Petroleum Geologists (AAPG) fosters scientific research, advances the science of geology, promotes technology and inspires high professional conduct through publications, conferences and educational opportunities for geoscientists. In addition, it disseminates the most current geological information available to the general public.
Through its network of international members, the Society for Sedimentary Geology (SEPM) is dedicated to the dissemination of scientific information on sedimentology, stratigraphy, paleontology, environmental sciences, marine geology, hydrogeology and many additional related specialties. The organization publishes two major scientific journals, the Journal of Sedimentary Research (JSR) and PALAIOS, in addition to producing technical conferences, short courses and special publications.
This site provides a gateway for information about the study of climatic conditions prior to the availability of instrumental data using sources such as tree rings, ice cores, corals, and ocean and lake sediments.
The topical directory on this page provides access to USGS science programs and activities by categories such as Atmosphere and Climate, Earth Characteristics, Geologic Processes, Geographic Analysis and Mapping, Natural Hazards, Techniques and Methods, and others. Each broad category is further subdivided into more specific topics.
