Oral sessions

Oral session formats will be allocated by the program committee after abstract submission and not all sessions will receive an oral component. The presentations selected for oral sessions are determined by the session conveners after abstract submission. It is not possible to request an oral presentation.

• Sessions will include a mix of in-person and pre-recorded virtual presentations.
• Online presenting authors will be required to upload a pre-recorded presentation in early December. 
• Sessions will not be live-streamed in real-time and will be recorded for on-demand viewing only.
• Online presenting authors and chairs will not participate in sessions via online platform and will not have the option for live participation in session or live Q&A with audience.
• Only online, asynchronous Q&A chat functionality will be available for online presenting authors.

Poster Sessions

The presentations selected for poster sessions are determined by the session conveners. Abstracts will be scheduled by conveners based on the presenter's selection of online or in-person participation.

• In-person posters
  • Scheduled sessions will take place in person in the poster hall in New Orleans.
  • In-person poster presenting authors will be required to print a paper poster and attend the conference venue and scheduled session on the specified date.
  • Presenting authors will also have the option to create an interactive or PDF poster and create pre-recorded videos or audio narrations to be displayed in the online iPoster gallery to extend visibility of their research.
• Online posters
  • Accepted online poster presenting authors must create an interactive poster to be displayed in the online iPoster gallery.
  • Online presenting authors will create their own self-scheduled video or chat time during the week of the meeting and  will not be scheduled in a live online session.
  • Presenting authors will have the opportunity to showcase their posters via asynchronous, online discussions with attendees via self-scheduled video or chat times and through direct messages. Scheduled chat times will be listed in the online program.
  • Presenters are also encouraged to create pre-recorded videos or audio narrations for attendees to view with their online poster.

GeoBurst Sessions (replacing the eLightning format this year)

The presentations selected for Geoburst sessions are determined by the session conveners and will include in-person participation only.

• The moderator briefly introduces the session and the presenters must create presentation slides in timed, rapid succession, one following another.
• A follow up poster session will be scheduled for connecting with individual presenters at their poster in the poster hall.
• In-person presenting authors must print a paper poster.
• In-person presenters also have the option to create an interactive or PDF poster and create pre-recorded videos or audio narrations to be displayed in the online iPoster gallery to extend visibility of their research.

AGU Membership Requirements

First authors, including invited authors, must be current AGU members or members of an affiliated society/organization. Join AGU to learn the value of membership. Membership unlocks opportunities to advance your career, connect with a global community, and access exclusive resources in the Earth and space sciences—empowering your journey every step of the way.

NOTE: Under certain circumstances, special membership exceptions may be requested for invited authors who are non-geoscientists. First authors who are not current AGU members, but are members of an affiliated society/organization or who are a non-geoscientist must request a membership waiver by 16 July. This waiver does not include AGU member benefits and does not waive the abstract submission fee.

Abstract fee Policy

The abstract submission fee is:

• A required and non-refundable processing fee for all abstract submissions, including invited abstracts.
  • Refunds will not be issued for abstracts that are withdrawn and resubmitted.
  • Do not withdraw a paid abstract submission to make edits or submit a new abstract. You are able to access and edit the draft or submitted abstract at any time until the submission deadline.
  • If you submit multiple abstracts to the meeting, you must pay the submission fee for each abstract.
• Separate from membership dues and meeting registration fees.
• Not based on approval of your abstract submission or attendance at the meeting.
• Payable by credit card only; wire payments or purchase orders cannot be accommodated.

The abstract submission fees are:

• Regular submission — $70
• Student submission — $40
• Low Income/Lower-Middle Income* - No Fee. If your affiliation is in one of these countries, the abstract fee will be waived during submission.

*Please see 2025 fiscal year World Bank country classifications by income level table for more information.

First Author Policy

First authors can submit up to two contributed abstracts (i.e., non-invited abstracts), as long as the second abstract is submitted to a session led by a different section from the first abstract.

Invited authors can submit up to three abstracts, including one contributed abstract, as long as one is submitted to a session led by a different section from the first abstract.

Scenarios in which a first author could submit two or three abstracts include:

Two abstracts:

• 1 contributed abstract to any session + 1 contributed abstract, as long as the additional abstract submission is to a section led by a different section from the first abstract, OR
• 1 contributed abstract to any session + 1 invited abstract to any session in any section, OR
• 2 invited abstracts to any session in any section.

Three abstracts:

• 1 contributed abstract to any session + 1 invited abstract to any session + 1 contributed abstract, as long as the additional abstract submission is to a session led by a different section from the first abstract, OR
• 2 invited abstracts to any session + 1 contributed abstract, as long as the additional abstract submission is in a different section from the first abstract.

* Please note, first authors may submit a second abstract to a session within the same section if it is listed as co-organized with a different section or the first author is a student or early career scientist.

Invited Author Policy

Conveners, please note the following:

• Conveners may invite up to two authors to submit abstracts for a session. Invited authors are not guaranteed an oral presentation and may receive a poster presentation. Please note the main objectives for inviting authors.
• Conveners should invite authors by 16 July to give authors sufficient time to accept the invitation, prepare their abstracts, and submit them. The invitation tool will be available to conveners until the abstract submission deadline on 30 July; however, please note AGU will not accept late submissions.

Invited authors, please note the following:

• After conveners add the invited authors to their sessions, invited authors will get an email from the abstract management platform with a direct link to start the process of submitting your invited abstract.
• Invited authors must use the provided link to submit their abstract. If the abstract is submitted through any other means, it will not be marked as invited.
• If you mistakenly submitted your abstract as a contributed abstract for the session or to another session, please do not withdraw it. Instead, contact AGU's Scientific Program Team to have the status of your abstract changed to invited.
• Invited authors are not guaranteed an oral presentation. The final decision on presentation format (oral, GeoBurst, or poster) will be made by the conveners and Program Committee.
• Invited authors are required to pay all fees associated with attending the meeting, including membership fees, abstract submission fees, and online or in-person meeting registration.

Conveners Submitting Abstracts

• Session conveners may not be the first author or presenting author on an invited abstract in the session they are convening, including early career and student conveners; however, conveners can be invited authors in other sessions, just not in their own sessions.
• Conveners may submit a contributed abstract to a session they are convening; however, they must be scheduled as a poster presentation.
  • For AGU25, Union, student and early career conveners are exempt from this rule and may be scheduled as oral presentations in their own session.
• Conveners who submit abstracts must pay all fees associated with attending the meeting, including membership fees, abstract submission fees, and online or in-person meeting registration if attending.
• Conveners who serve as session chairs must pay the online or in-person meeting registration fee to attend.
• Conveners who are not attending the meeting do not need to pay the meeting registration fee.
