Geophysics in the Oceans: Observations, Modeling, and New Frontiers
Session ID#: 250430
Session Description:
The ocean basins are a fundamental expression of plate tectonics, covering the majority of Earth’s surface and encompassing the entire plate life cycle. However, the seafloor is sparsely instrumented compared to the continents. Ongoing concerted efforts to deploy in-situ geophysical arrays help fill these observational gaps, illuminating fundamental solid earth processes from localized submarine volcanism, to hydration of oceanic crust and lithosphere, to multi-scale mantle convection. In addition, promising new seafloor technologies have come online, such as DAS and GNSS-Acoustic, expanding the range of accessible spatial and time sampling. We invite contributions that integrate seafloor observations to investigate chemical and physical interactions between the ocean, crust, lithosphere, and/or asthenosphere. Topics include imaging and/or geodynamic modeling of the oceanic lithosphere/asthenosphere, lower mantle discontinuities, mantle convection and plumes, presence/role of melt and volatiles, intraplate volcanism, seafloor geodesy, deformation/seismicity at plate boundaries, and new seafloor instrumentation and analysis techniques.
