2020 Collecting Geophysical Observations from the Seafloor

Course Information

  • Dates: Tuesday, August 18, 2020
  • Time: 9-11 am PT | 10 am-12 pm MT | 11 am-1 pm CT | 12-2 pm ET
  • Location: Online via Zoom

Delving into the oceans to record seismic and geodetic observations from the seafloor has remained a challenging frontier in geophysical research. Improving our understanding of structure and hazards at subduction zones, ocean basins, coasts, and islands will require improving coverage of the seafloor through development and deployment of specialized instrumentation. Different research targets and analysis techniques will have different requirements (e.g. duration, location/depth, timing quality, burial, etc.), however there is significant overlap in objectives for at-sea operations. This SIG will explore convergence of marine research targets between the geodetic and seismic communities and spark discussion on how current and future resources can be best leveraged for high-impact science.
