The FRES program will support research in Earth systems from the core through the critical zone. The project may focus on all or part of the surface, continental lithospheric, and deeper Earth systems over the entire range of temporal and spatial scales. FRES projects should have a larger scientific scope and budget than those considered for funding by disciplinary programs in the Division of Earth Sciences (EAR). FRES projects may be interdisciplinary studies that do not fit well within EAR's disciplinary programs or cannot be routinely managed by sharing between disciplinary programs. Innovative proposals within a single disciplinary area with outcomes of potential broad relevance to Earth Science research are also encouraged. Investigations may employ any combination of field, laboratory, and computational studies with observational, theoretical, or experimental approaches. Projects should be focused on topics that meet the guidelines for research funded by the Division of Earth Sciences.
