Emerging Topics in Biogeochemical Cycles (ETBC)

NSF's implementation of the revised 2 CFR

NSF Financial Assistance awards (grants and cooperative agreements) made on or after October 1, 2024, will be subject to the applicable set of award conditions, dated October 1, 2024, available on the NSF website. These terms and conditions are consistent with the revised guidance specified in the OMB Guidance for Federal Financial Assistance published in the Federal Register on April 22, 2024.

Important information for proposers

All proposals must be submitted in accordance with the requirements specified in this funding opportunity and in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. It is the responsibility of the proposer to ensure that the proposal meets these requirements. Submitting a proposal prior to a specified deadline does not negate this requirement.

Updates to NSF Research Security Policies

On July 10, 2025, NSF issued an Important Notice providing updates to the agency's research security policies, including a research security training requirement, Malign Foreign Talent Recruitment Program annual certification requirement, prohibition on Confucius institutes and an updated FFDR reporting and submission timeline.

Synopsis

The Directorate for Geosciences (GEO) and the Directorate for Biological Sciences (BIO) are enhancing support for interdisciplinary research which bridges across the biological, atmospheric, geological, oceanographic and hydrological sciences, in the area of biogeochemical cycles and processes.

We seek to support research that will advance our quantitative and/or mechanistic understanding of biogeochemical cycles, including the water cycle. Competitive proposals should integrate physical, geological, chemical, and/or hydrologic processes with biological processes over various temporal and/or spatial scales and/or various levels of biological organization.

Proposals must bridge the biological and geosciences disciplines and be relevant to at least one program in the BIO Directorate and at least one Program in the GEO Directorate. Proposals involving programs in two different divisions in GEO are also permitted, but they must address the goals of the Dear Colleague Letter (http://www.nsf.gov/pubs/2009/nsf09030/nsf09030.jsp).

This is not a special competition or new program. ETBC proposals should be submitted to an existing GEO or BIO program according to the program’s regular target or deadline dates.

Program contacts

Proposals aimed at advancing the quantitative and/or mechanistic understanding of biogeochemical cycles over various temporal and/or spatial scales can continue to be submitted to relevant programs in the Geosciences and Biological Sciences Directorates at their regular target or deadline dates. Interdisciplinary proposals bridging the geosciences and biological science disciplines or subdisciplines in the Geosciences Directorate will be co-reviewed by the appropriate programs. Investigators are encouraged to contact the program directors for guidance before the submission.
