The National Science Foundation (NSF) is seeking proposals for the Frontier Research in Earth Sciences (FRES) grant program, which focuses on advancing the understanding of integrated Earth systems. The program aims to provide opportunities for collaborative, multidisciplinary research into the operation, dynamics, and complexity of Earth systems, with a specific focus on subsystems that include all or part of the continental, terrestrial, and deep Earth components. Key areas of interest include, but are not limited to, the study of linkages among tectonics, climate, landscape change, topography, and geochemical cycles. The evaluation criteria will likely emphasize the scientific merit, broader impacts, and feasibility of the proposed research. The deadline for this opportunity has not been provided. The FRES grants are part of the NSF's Geosciences program, which supports fundamental research and educational initiatives across various Earth science disciplines. Typical award sizes for this program range from $79,139 to $4,893,936, with project durations typically spanning 1-5 years. The work is expected to be performed at academic facilities, field sites, scientific observatories, and research vessels across the United States, with opportunities for interdisciplinary and international collaboration.
