- Registration is optional but highly recommended. If you were registered in 2022, you don’t need to register again.
- To register, please email email@example.com (Trevor Dumitru) using subject line “TPG Reg”. The only information we need is your email address. We’ll email you updates, weekly reminders, changes, etc.
- We may not read emails with subject line “TPG Reg,” so please send questions, etc. using subject line “TPG Questions”.
- Talk level: Advanced; directed mainly toward graduate students, post-docs, faculty, and geoscientists with interests in TPG.
- Our Zoom limit is 500 people. In the unlikely event a meeting exceeds 500 and you can’t join, please email us so we’ll know (but we won’t be able to help for that talk).
