Fall Meeting is organized into seven interdisciplinary themes that encompass many of the sessions. These sessions will be signaled in the Program book by symbols that allow attendees to concentrate on areas of particular interest, regardless of the AGU Section hosting that session. The themes are:

Climate and Global Change, Including El Niño
Deep Earth Processes and Structures (SEDI)
Educational Enrichment
Polar Processes
Mineral and Rock Physics
Human Impacts on the Environment
