After an all-virtual conference last year, the 2021 American Geophysical Union (AGU) Fall Meeting will be a hybrid conference, allowing participants the opportunity to present either in-person in New Orleans, LA, or virtually, while also streaming plenty of talks and presentations online. The conference, which attracts scientists from around the world to discuss the latest in geoscience research, will take place from December 13-17. Plenty of representatives from MIT’s Department of Earth, Atmosphere and Planetary Sciences (EAPS) will be in attendance. Below is a schedule of some of the EAPS research being presented.

All times are listed in CST.
