Session Allocation and Scheduling

There are two traditional types of sessions held during AGU Fall Meeting—oral and poster. Abstract submitters select their presentation type preference as either only a poster or to be designated by the Program Committee/session conveners (poster or oral) during the abstract submission process. The only exception to this policy is if the session is an alternate format (e.g. eLightning).

  • Convener Availability: At least one of the conveners (Primary Liaison) must be available after the abstract submission deadline and during the scheduling period to respond to any Program Committee requests. Because of content overlap and number of abstracts submitted, some sessions may be merged at this time at the discretion of the Program Committee.
  • Session Allocation: After abstract submission, the designated section Program Committee representative will determine the session type (poster session, or a combination of oral and poster session) and number of sessions allocated to each submitted session. If you have any questions regarding your allocated sessions, please contact the appropriate Program Committee Representative.
  • Session Scheduling: Conveners will have from Tuesday, 21 August through noon EDT, Friday, 31 August 2018 to review and organize the abstracts submitted to their sessions by assigning the presentation order with poster sessions and duration of presentations if an oral session is allotted. Conveners must be an AGU member in order to access the online abstract scheduling system. Conveners must also designate two (2) session chairs (do not have to be existing conveners) and one (1) Outstanding Student Presentation Award (OSPA) liaison for each allocated session during this time.
    Session scheduling must be completed in the online abstract management system by 31 August, prior to the Program Committee scheduling meeting. Session conveners will no longer have access to their sessions once the Program Committee scheduling meeting begins. During the scheduling meeting, the Program Committee will schedule any sessions not scheduled by the conveners as they see fit and assign days, times, and meeting rooms for each approved session.

          Note: Invited authors are not guaranteed an oral presentation.

Final Program/Scientific Program

In early October 2018, abstract acceptance notices will be distributed electronically, and the final program will be available online.

After the program has been published in early October, please note that authors will be required to accept or decline their presentation. If the author declines, the abstract will be withdrawn from your session. Please note that, if you are chairing multiple sessions and also submitted abstracts to the scientific program, the Program Committee CANNOT guarantee that you will be free of scheduling conflicts at the meeting, due to the size of the program. Please ensure the co-conveners of the session are available to step in to chair a session if the need arises.

Replacing an Empty Oral Presentation

If the withdrawal is from an oral session, the session conveners can request that a poster presentation from the accompanying poster session be moved to replace the withdrawn oral presentation. This can be done only to and from accompanying sessions and only with the authors’ explicit consent. Please send an email to with the details of the withdrawn abstract, the details of the abstract that will be moved into the oral presentation slot, and the email or message in which the author gave consent to being moved.

Note: New abstracts CANNOT be added to fill empty slots in either oral or poster sessions. Also, after the program has been finalized, poster presentations CANNOT be moved to different poster sessions or boards, due to the logistical layout of the poster hall.
