The Geological Society of America® (est. 1888)

Our Vision
To be the premier geological society supporting the global community in scientific discovery, communication, and application of geoscience knowledge.
Our Mission
To advance geoscience research and discovery, service to society, stewardship of Earth, and the geosciences profession.

The Geological Society of America (GSA) is a global professional society with a membership of more than 20,000 individuals in more than 100 countries. GSA provides access to elements that are essential to the professional growth of earth scientists at all levels of expertise and from all sectors: academic, government, business, and industry.

GSA's Commitment to Diversity

The Geological Society of America (GSA) affirms its belief and commitment to diversity and will continue to develop its diverse base. GSA is dedicated to maintaining an organizational climate where differing ideas, abilities, backgrounds, and needs are fostered with opportunities for members from divergent experiences to participate and contribute. GSA recognizes that diverse perspectives are important and necessary for responsible and representative decision making and leadership. Therefore, GSA strongly encourages the participation in any GSA activity of all its members regardless of race, sex, creed, age, sexual orientation, national origin, religion, or disability and will undertake reasonable efforts to ensure that its activities are open to all.
