The Geological Society of America (GSA) is a scholarly organization dedicated to the advancement of the geosciences. Founded in 1888, the GSA serves members from academic institutions, government, and industry around the world by promoting the study of geological processes, encouraging professional cooperation among scientists, and disseminating research findings through its meetings, publications, and educational programs. The society publishes a variety of scientific literature, including the prominent journal Geology, and organizes annual meetings that attract thousands of geoscientists who share research, network, and discuss trends in the field. The GSA also provides grants and awards to support research and recognizes outstanding contributions to the geosciences with prestigious awards.
