The National Science Foundation (NSF) is inviting proposals for the Arctic Doctoral Dissertation Research Improvement Grants (Arctic DDRIG), aimed at supporting dissertation-level research related to the Arctic region. Eligible applicants include institutions of higher education in the U.S., with proposals submitted by dissertation advisors on behalf of graduate students, who must be the primary authors of the proposals. This funding opportunity, which has an estimated total program funding of $1,250,000, seeks to enhance understanding of the Arctic's changing environment and social systems while promoting workforce development and diversity in STEM fields. Proposals are due by December 16, 2024, and interested parties can reach out to NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
