The technical program features approximately 700 quality presentations in 115 diverse sessions, including eight special sessions and one special global session.

Geoscience professionals from all geophysical disciplines and all parts of the world are represented and will share their latest case histories, technological advancements, and research discoveries.

The technical program will begin Monday at 1:50 p.m., following the SEG20 Opening Session and Presidential Address. Oral sessions will run through Wednesday at 5:10 p.m., and poster sessions will run through Wednesday at 4:20 p.m. Immediately following, postconvention workshops will take place all day Thursday and a half day Friday.

Special SessionsThese dedicated special sessions will be offered to complement the technical program:

• Geophysical Exploration of the Solar System by NASA

• Geophysics in Medicine• Geoscientists Without Borders® and

Humanitarian Geophysics• Geothermal Exploration• Machine Learning in the Near Surface• Recent Advances and the Road Ahead• SEG/AGU Hydrogeophysics• Urban Geophysics

Special Global Session

• Africa - Geophysical Exploration

Technical Program Information

Questions and DiscussionAll Technical Program speakers will participate in the Question and Discussion portion during and immediately following their presentation. This is done via the “Open Chat” console within the virtual platform. During this question and discussion, you will have the opportunity to ask speakers questions in regards to their presentation. To access, you will need to “Enroll” in the session within the virtual platform.

In addition, the virtual platform will have predefined group chat rooms under “Social” to help facilitate ongoing discussions that may occur outside of the presentation times. The predefined group chat rooms will be set up by Session Topics under “# All Groups.” See following examples:

• ACQ 1: Marine Seismic would be Social room “Acquisition and Survey Design Chat Room”

• NS 1: Surface Waves Analysis would be Social room “Near Surface Chat Room”• SS 2: Recent Advances and the Road Ahead would be Social room “Special Session

Chat Room”

Virtual group chat rooms will be available until the meeting is taken offline on 13 November 2020.
