PD-05-1743 National Facilities

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 Program supports science that includes: Structure, composition, tectonics, and evolution of the oceanic lithosphere Paleoceanography, paleoclimate, and sea level change Submarine volcanology, petrology and geochemistry of the oceanic crust and upper mantle lithosphere Marine hydrogeology, water-rock interaction, seeps and gas hydrates Hydrothermal venting and in situ fluid processes, and associated geochemistry Geochemical indicators of life operating below the seafloor Marine sedimentology, stratigraphy, sediment transport, and diagenesis Mid-ocean ridge spreading, back-arc rifting, transform processes, and ocean island/seamount formation and evolution Submarine components of subduction zone systems and passive margins Marine geohazards (e.g., earthquakes, faulting, mass wasting, geological aspects of tsunamis) Coastal processes (e.g., geological aspects of hurricanes, sea-level change, erosion, offshore deposition) The Marine Geology and Geophysics Program supports acquisition of new field data and the leveraging of and/or synthesis of existing data. The program supports analytical and laboratory experimental projects, methods development, and modeling. All activities should have relevance to and advance the understanding of marine geoscience processes. 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.

The Structure and Physics of the Solid Earth Program (SPSE) aims to advance fundamental knowledge about the ongoing dynamical processes over the age of the Earth that evolve the structure of planet Earth and underpin geohazards. SPSE supports research at all temporal and spatial scales, from the Earth's core to its crust. Through laboratory, field, theoretical, and computational studies, the program encompasses a wide range of disciplines including structural geology, tectonics, and geophysics. Research in these areas can help improve our understanding of natural hazards including earthquakes and mass flows, as well as Earth's formation and its magnetic field.

The Water, Landscape, and Critical Zone Processes program supports research on the Earth's near-surface environment and how that environment responds to change. The Program focuses on the complex interplay amongst and between hydrologic, geomorphic, and geochemical processes and how they regulate the structure and function of the Earth's near surface. These processes drive weathering and soil development, control water availability and quality, and help regulate the Earth's climate system, all of which are important for natural resource sustainability and mitigation of natural hazards. It is expected that the research funded in this program will advance fundamental knowledge in Earth surface processes, leading to transformational discoveries in Earth Sciences.
