The Antarctic Research Not Requiring U.S. Antarctic Program (USAP) Field Support grant opportunity, administered by the National Science Foundation (NSF), focuses on supporting cutting-edge research in the Antarctic region and the Southern Ocean. This program seeks to fund studies that advance the understanding of interactions between Antarctic systems and global processes, addressing biological, geochemical, and physical changes on both regional and global scales. Research that expands knowledge of Antarctic biota, systems, and processes is a key focus, as well as projects that utilize the region's unique characteristics as a scientific observation platform. The program also emphasizes building capacity and enhancing diversity within the U.S. polar science workforce.

This funding opportunity targets research that does not require logistical support from the U.S. Antarctic Program (USAP). Projects may use existing Antarctic data, samples, or analog sites outside of Antarctica to conduct investigations relevant to polar science. Researchers requiring logistics or operational support through other Antarctic programs or organizations are encouraged to consult an Antarctic Sciences Program Officer for guidance. The program encourages interdisciplinary research and approaches that integrate perspectives from multiple scientific fields.

Eligible applicants include U.S.-based institutions of higher education, including two- and four-year colleges and universities, as well as non-profit, non-academic organizations such as independent museums, observatories, research laboratories, and professional societies directly associated with educational or research activities. Federally recognized Tribal Nations are also eligible to apply. International branch campuses of U.S. institutions of higher education may receive funding but must provide justification for why project activities cannot occur at a U.S. campus.

The program has an estimated total funding amount of $60,000,000, though specific award ceilings and floors are not provided. Applications are due by June 2, 2025, with an archive date of July 1, 2028. The solicitation emphasizes projects that improve decision-making regarding environmental change, contribute to Earth systems science, and advance the understanding of dynamic linkages in the Antarctic and Southern Ocean.

Applicants are advised to review the NSF solicitation document (NSF Publication 25-526) for detailed submission requirements, evaluation criteria, and additional guidance.
