The National Science Foundation is offering a grant opportunity titled "Cooperative Studies of the Earth's Deep Interior". This grant aims to support collaborative and interdisciplinary studies of the Earth's interior within the framework of the community-based initiative known as Cooperative Studies of the Earth's Deep Interior (CSEDI). The funding will be used to conduct basic research on the character and dynamics of the Earth's mantle and core, their influence on the evolution of the Earth, and processes operating within the deep interior that affect or are expressed on the Earth's surface. The projects may involve field, laboratory, and computational studies with observational, theoretical, or experimental approaches. The grant is open to non-profit, non-academic organizations, institutions of higher education, and other eligible institutions. The deadline for proposal submission is September 23, 2024. The estimated total program funding is $3,000,000, and it is expected that 15 awards will be granted.
