Marine Geology and Geophysics (MG&G)

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)
