The Antarctic Sciences Section (ANT) of the Office of Polar Programs (OPP) supports cutting-edge research that: Improves understanding of interactions among the Antarctic region and global systems; Expands fundamental knowledge of Antarctic systems, biota, and processes; Utilizes previously collected samples or focuses on non-field-supported themes; Utilizes the unique characteristics of the Antarctic region as a science observing platform; and Builds capacity and enhances diversity in the US workforce for polar-related science. ANT encourages and supports non-fieldworkresearch that crosses and combines disciplinary perspectives and approaches from other fields.ANT encourages and supports research that uses existing data and samples and other research not requiring a presence in Antarctica. Proposals that require USAP support for field work must use solicitation NSF 23-509,Antarctic Research Requiring U.S. Antarctic Program (USAP) Support for Fieldwork. Diversifying and broadening participation is a priority for the Antarctic Sciences Section. ANT encourages the leadership, partnership, and contributions of individuals who are members of groups underrepresented and/or underserved in all opportunities in STEM education programs and careers. ANT promotes and expects that all individuals, including those from groups that are underrepresented and/or underserved in STEM are treated equitably and inclusively throughout the Foundations proposal and award process. The Antarctic Sciences Section coordinates with programs across NSF and with other federal and international partners to co-review and co-fund Antarctic-related proposals as appropriate.
