Poster Session Chair Resources

To prepare for your session, please review the information below.

  • Check the online program for any changes or updates to your session. Session chairs may access the contact information for presenting authors in your session via the User Portal or presentation management system.
  • Refer to the Meetings Code of Conduct and the Best Practices for Inclusive Remote Meetings guidance on potential issues you may face as a convener or session chair.
  • Make sure online presenters have selected at least a one-hour timeframe to be available to present during the session’s scheduled time. Authors also have the option of scheduling additional chat times during the meeting at their discretion.
  • Session conveners not in attendance are also encouraged to attend these live chats to engage with the authors if possible.

AGU is excited to offer training for the presenters and chairs of #AGU21 Fall Meeting. Whether this is your first time chairing an AGU Fall Meeting session or you are an experienced Fall Meeting session chair, you are encouraged to attend the live session chair trainings or to view the trainings and resources available online prior to the start of the meeting. These trainings will offer practical, research-based advice on facilitating sessions. Please check back for updated schedule of trainings, resources and AGU staff office hours.  

  • Coming soon: AGU will provide a Session Chair Checklist with tips and guidelines for facilitating the best session.
  • Reach out in advance to the presenting authors in your session and review the timing of the discussion session, how the session will run and discuss in advance a general discussion topic based on the presentations. This session format provides an opportunity to discuss or highlight some of the larger science questions around the presentations or explore future needs and challenges.

To prepare for your in-person or online participation, please review the information below.

AGU would like to assure that all meeting participants feel safe, welcomed and included and that our meetings promote and help reflect diversity, inclusion and excellence in science.

  • Please plan to arrive in the poster area before your session is scheduled to start.
  • Make sure authors’ poster boards are numbered properly.
  • Online presenters in the hybrid poster sessions will be assigned a poster board within the poster hall on the day of their session. AGU will create signage that session chairs will place on the boards of online presenters in hybrid sessions to encourage in-person attendees to visit online posters.
  • Make sure authors are beginning to set up their posters before the start of the session and are not experiencing problems. We ask that presenters set up their posters by 08:00 CST as posters remain up on their board all day.
  • Make sure authors have clearly posted the time when they will be at their boards. These signs can be picked up at the Poster Assistance Booth.
  • Note any poster boards that are not withdrawn but are still empty. The evaluation survey referenced below will ask for any “no-show” presentations.
  • Help any authors who are having trouble with layout, setup or equipment.
  • Encourage participation by introducing individuals in the area to specific authors and performing “crowd control” as necessary.
  • Please be aware of signs of aggressive questioning which may border on bullying, especially if directed towards students or early career scientists. Please intervene in real time if you witness such behavior.
  • No papers may be added or moved to another session and poster presentations CANNOT be moved to different poster sessions due to the logistical layout of the poster hall.
  • Should any problem develop with poster set-up, facilities or equipment, contact an AGU staff person at the Poster Assistance Desk.
  • Remind authors to remove their posters by 18:30 CST on the day of their presentation. Any posters not removed from poster boards by 18:30 will be recycled.
  • Please note, 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.

Hybrid session chairs can schedule a separate online "poster summary session" for additional interaction and exposure with the in-person and online poster presenters at a time of their choosing. These fully online summary sessions, separate from the dedicated poster hall hours can be scheduled throughout the meeting and will be organized by session chairs only. Session chairs should consider the availability of poster presenters when scheduling and coordinate with the presenters in the session so they can participate and reserve their calendars. Additional details and the reservation tool will be available in early November.

Online-only poster sessions at the AGU Fall Meeting will make use of Zoom Webinar. The live discussion sessions will be recorded and available for on-demand viewing 72 hours, for registered attendees, after the session is scheduled and available for viewing during and after the meeting through February 2022. 


When can presenters and chairs access the online platform?
Presenters and chairs will log in to the online platform 20 minutes prior to start of session and will be provided with the direct link to the session in advance.


What is required of the presenter? 
Presenters will give a brief introduction and overview of their iPoster or PDF poster and will participate in moderated Q&A with the other authors, chairs and registered attendees in the session. 


What is the role of the session chair?
The session chairs will moderate the session, introduce presenters and moderate Q&A with authors and attendees. 


Will there be technical support? 
Yes, technical support will be available to help with any technical issues, assist in managing online questions and beginning and closing live sessions.

Interactive Poster Presentation Format

Online and in-person presenters should create and publish your iPoster by the extended deadline of 9 DecemberPresenting authors must be registered to publish the poster to the online gallery. Updates can be made until 31 December.

eLightning or Poster prsenters, if they have trouble accessing the iPoster Editor Site or have any technical questions, please contact our Support Desk here. When you communicate with Support, please use this Conference Code: AGUFM2021.

Both in-person and online presenters will utilize the aMuze! iPosterSessions platform, which has been used by AGU for the last four years and is a flexible HTML based poster format that allows authors to create interactive presentations that can include high-resolution images, videos and animations, voice-over narrations and scrolling content. At the most basic, you can simply paste in text and images from a PDF poster into one of several existing templates. Authors also have the option of recording a brief introduction or summary recording linked in the presentation. Although the deadline to upload an online poster presentation is extended to 9 December, please note that authors will have access to make any updates to their presentations until 31 December.
