The Office of Science at the Department of Energy (DOE) is inviting applications for funding under the Environmental System Science (ESS) program, aimed at enhancing the understanding of terrestrial systems and their ecological interactions. This funding opportunity focuses on advancing foundational knowledge through research in three key areas: plant-soil-microbe interactions affecting biogeochemical processes, synthesis studies relevant to U.S. southeast coastal systems, and the contributions of marginal and degraded lands to ecological processes. With an estimated total program funding of $6 million, the DOE plans to award between 6 to 10 grants ranging from $100,000 to $1,000,000. Pre-applications are due by December 11, 2024, with final submissions required by March 13, 2025. For further inquiries, applicants can contact the grantor at SC.GrantsandContracts@science.doe.gov.
