Sections reflect the scientific breadth of the Union. These groups are responsible for fostering scientific discussion and collaboration among members who affiliate with them.

Sections connect you with other scientists in your research area. Sections offer many opportunities to engage with AGU. Sections play a role in identifying emerging issues, providing member input, and nominating scientists for honors and recognition.

The President and President-elect from each Section serve on the AGU Council.
