The National Science Foundation (NSF) is offering a grant opportunity under the Geobiology and Low-Temperature Geochemistry Program, aimed at supporting research on geochemical processes in terrestrial Earth's surface systems and their interactions with biological processes. Proposals are encouraged to explore field, laboratory, theoretical, or modeling studies at various spatial and temporal scales, with a focus on transformational and cutting-edge research, including the development of geochemical proxies and analytical techniques. This interdisciplinary program interfaces with other NSF programs across geosciences, biology, chemistry, and engineering, with an estimated total funding of $9 million and approximately 30 awards expected. Proposals can be submitted at any time, and interested applicants may contact NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
