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 (

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.
