Synthesis and integration of EarthScope scientific results for Alaska

Organizers: Jeff Freymueller (Michigan State University), Rick Aster (Colorado State University), Julie Elliott (Purdue University), Sarah Roeske (UC Davis)

A virtual workshop is planned for the week of May 10-14, which will be the culmination of a series of weekly workshops (listed below). This page will be updated with additional information and links to seminar recordings.

The goal of the series and of the workshop is to foster synthesis and integration of EarthScope scientific results for Alaska. Seminars span a broad range of topics within the scope of the EarthScope science plan (and including related topics supported by other programs).

Seminars are scheduled every Monday from 3-4pm ET (with a few exceptions) through the end of April. Most will feature two roughly 30-minute talks.

We have a mailing list for this series—if you want to be on the mailing list to receive the registration links and other notifications, please send an email to Sarah Roeske (smroeskeat
