Program & Schedule

Session Formats

AGU23 will offer session formats that foster and encourage discussion across the meeting and will incorporate design principles and will offer session formats that foster and encourage discussion across the meeting including: 

  • Expanding open discussion and engagement times.
  • Recording most sessions so they are available to all attendees.
  • Accessing most presentations and posters online.
  • Accommodating virtual presentations as much as possible.

Keynotes & Plenaries

These featured sessions cover a diverse range of Earth and space science as well as overarching societal topics. World-renowned scientists and leaders will weave the theme "Wide Open Science" into their remarks to convey how critical it to make Earth and space science accessible beyond the scientific community. 

Named Lectures

These award lectures are curated by AGU sections to recognize distinguished scientists with proven leadership and discoveries in their fields of science. They showcase the breadth and depth of discovery and solution science spearheaded by AGU members. 

Union Session

Reviewed and approved by the program committee, these 90-minute sessions cover topics of broad interest that resonate with the entire Earth and space science community and include a mix of invited:

  • panels
  • presentations
  • moderated discussions

Please note, conveners may also opt to accept contributed abstracts and convene a companion in-person and online poster session. Online poster sessions will be scheduled in late January 2024


Proposed by the AGU community, these sessions (also known as meetings-within-a-meeting or innovative sessions) focus on interdisciplinary topics and convergent science themes of interest to a broad audience. Proposals that include a creative mix of dynamic programming that bring in scientific thought leaders connected to AGU’s mission which encompass diverse presenters and conveners are particularly welcome. Approved innovations:

  • Will have a creative and dynamic format with attendee engagement.
  • May range in length from half-to full-day sessions designed around a theme.
  • May include a short presentations, panels, and breakout presentations. 
  • May include a mix of in-person and online presentations. 

Oral Session

These 90-minute scientific sessions will be allocated by the program committee after abstract submission. The sessions will be hybrid and include talks and moderated Q&A discussions with in-person and online presenters and the audience.

eLightning Session

These 90-minute scientific sessions will be allocated by the program committee after abstract submission. These live, in-person only 90-minute sessions begin with three-minute lightning talks from each presenter with:

  • An overview of their dynamic, digital, and interactive poster.
  • Discussion of their digital poster at their assigned touchscreen monitor following the lightning talk.

Poster Session

AGU23 will offer in-person and online poster presentation options. All approved scientific sessions will receive at the minimum a poster component. Sessions will be allocated by the program committee after abstract submission.

  • In-person poster sessions will take place in the poster hall in San Francisco. There will be no hybrid poster sessions. 
  • Online poster sessions will take place in late January, 2024.
  • For poster presentations, authors will be assigned to an in-person or online poster presentation format by the session’s conveners. Poster presentation will be assigned as in-person or online based on the location selection by the author during abstract submission. Authors cannot change their presentation location after the abstract submission deadline has passed. Please keep this in mind while making the selection.
  • All in-person and online poster presenters will have the opportunity to create a digital poster. AGU will offer an online poster gallery and viewing areas throughout the poster hall in San Francisco to enable in-person attendees to engage with the online posters and presenters.

Town Hall

Proposed by the AGU community (including AGU staff) and open to all meeting participants, these one-hour sessions, are best for:

  • Collecting feedback or raising awareness.
  • Government agencies, academic programs, special projects and other focused interest groups to deliver updates and gather input from the broader AGU community.
  • Presentation, roundtable or panel discussion formats.

Approved town halls will be:

  • Open to all meeting attendees
  • Focused on topics that do not compete with, substitute or duplicate scientific or learning sessions.
  • Scheduled onsite in San Francisco and online only town halls will be held the week prior to AGU23.

Learning Workshops

These workshops are free from the format constraints of traditional scientific sessions. The transdisciplinary-focused workshops range from 90 minutes, and half- to full-day sessions and provide a way to share knowledge and skills while promoting discussion and interaction.

Approved workshops:

  • May include a mix of in-person and online presentations.
  • Will require separate registration from the meeting registration.
