The Marine Geology and Geophysics Core Program supports research on all aspects of the geology and geophysics of the present ocean basins and margins, as well as those of the Great Lakes. The Marine Geology and Geophysics Program is interested in supporting new ideas and cutting-edge research. It supports field, analytical, and laboratory experimental projects; methods development; modeling; and the re-analysis and/or synthesis of existing data. The Program interfaces with NSF programs across the Geosciences and across the Agency. For proposals that cross between Programs, proposers should contact the relevant Programs to seek guidance on submission.
