Opportunity snapshot. This Grants.gov announcement - Geobiology and Low-Temperature Geochemistry (GG) - is cataloged under number 15-559 and tied to CFDA assistance listing 47.050, posted by U.S. National Science Foundation. Grants.gov currently shows the opportunity as closed, first posted on June 6, 2025. The funding category is Discretionary, delivered as a grant.
Award economics. The award range on file is $250,000 -- $1,500,000. The agency has projected $6.3 million in total estimated funding for this announcement. It expects to issue 30 awards. If the agency funds the expected 30 awards from the $6.3 million estimated pool, the average award works out to roughly $210,000. Cost sharing is not required, so applicants do not need to commit matching funds to be competitive on this opportunity. Federal award ranges are often upper bounds; actual allocations reflect program appropriations, the strength of the applicant pool, and the evaluation committee's scoring.
Deadline and action path. This opportunity is closed. Monitoring the parent program page is the most reliable way to catch re-announcements in the next funding cycle. Every Grants.gov submission requires an active SAM.gov registration and a Unique Entity ID. Review the Eligibility section below carefully, federal eligibility categories (nonprofit, state or local government, tribal, individual, educational institution, small business) have distinct registration and reporting requirements. Pre-application outreach to the listed agency contact is permitted and often welcomed, it helps clarify scope and scoring priorities. Before acting on the deadline or award figures above, verify them directly on the official Grants.gov listing, amendments can change dates and amounts after this page was last refreshed.

Description
The Geobiology and Low-Temperature Geochemistry Program focuses on geochemical processes in terrestrial Earth’s surface environmental systems, as well as the interaction of geochemical and biological processes. The program supports field, laboratory, theoretical, and modeling studies of these processes and related mechanisms at all spatial and temporal scales. Studies may address: 1) inorganic and/or organic geochemical processes occurring at or near the Earth’s surface now and in the past, and across the broad spectrum of interfaces ranging in scale from planetary and regional to mineral-surface and supramolecular; 2) the role of life in the transformation and evolution of Earth’s geochemical cycles; 3) surficial chemical and biogeochemical systems and cycles, including their modification through environmental change and human activities; 4) low-temperature aqueous geochemical processes; 5) mineralogy and chemistry of earth materials; 6) geomicrobiology and biomineralization processes; and 7) medical mineralogy and geochemistry. The Program encourages research that focusses on geochemical processes as they are coupled with physical and biological processes in the critical zone. The Program also supports work on the development of tools, methods, and models for the advancement of low-temperature geochemistry and geobiology. The Geobiology and Low-Temperature Geochemistry Program is interested in supporting transformational and cutting-edge research. The Program is highly interdisciplinary and interfaces with other programs within the Earth Surface Section and with programs in biology, chemistry and engineering.
