WELCOME

Hello Attendees!

Welcome to The University of Arizona Department of Geosciences 48th annual GeoDaze Symposium! GeoDaze is an entirely student-run research symposium that has become a hallmark at the University of Arizona for its presentation of high-quality research from undergraduate and graduate students. Each year, GeoDaze is made possible by generous donations from individuals and corporate sponsors. We thank you for your continued support.

This year, the social distancing requirements imposed by the COVID-19 outbreak have resulted in some changes. We’re going 100% virtual! All student presentations have been pre-recorded and will be available for viewing at www.geodaze.com from April 20th to 24th, 2020. Live events — including question and answer sessions, an awards ceremony, and a happy hour — will take place on Thursday, April 23rd and Friday, April 24th. We invite you to join us for these events to continue the time-honored GeoDaze tradition of student-to-professional interaction. Links to live events can be found on the website.

GeoDaze is proud to present 25 oral and 25 poster presentations from Geosciences graduate and undergraduate students. The diversity of these presentations spans multiple continents and a variety of research interests. We have prepared a suggested viewing schedule to align the viewing of presentations with the live events, and we welcome you to follow along.

We want to thank everyone who helped support and organize GeoDaze in this unique year. Your tireless efforts ensure the continued success of GeoDaze!
