Welcome | i

Welcome to the 3rd Annual EarthWeek!

School of Earth and Environmental Sciences (SEES) at the University of Arizona. The event is organized by graduate students from each department and will span three days at the end of March. This year’s EarthWeek includes a plenary session with the broad theme of climate and the Southwest amongst other interdisciplinary endeavors.

EarthWeek kicks off on Wednesday, March 28, with two conferences: El Día del Agua, organized by the Department of Hydrology, and the SEES Joint Sessions hosted by the Laboratory of Tree Ring Research (LTRR). LTRR Director Steve Leavitt will introduce the SEES Joint Sessions. The joint sessions are designed to be interdisciplinary and are open to student presenters from all departments. Keynote speaker Walter Ilman, a hy-drologist, will cap off the day’s talks.

EarthWeek continues on Thursday, March 29, with two more conferences: SWES Day, hosted by the Department of Soil, Water and Environmental Science, and the 40th annual GeoDaze, hosted by the Department of Geosciences. During the afternoon, a special SEES-wide plenary session, entitled Climate in the Southwest, will allow top student speakers from each department to compete for a $1,000 cash prize. After the plenary ses-sion, EarthWeek keynote speaker Susan Joy Hassol will discuss the challenges of com-municating climate science to the public.

EarthWeek concludes on Friday, March 30, with the Atmospheric and Interdisciplinary

Research (AIR) Symposium, hosted by the Department of Atmospheric Sciences, and the second day of GeoDaze. At the close of the day, GeoDaze keynote speaker Katharine

Huntington will address the nexus of tectonics, climate, and landscape evolution using exciting new geochemical techniques.

GeoDaze -ner Caverns State Park.

EarthWeek will be held in the Student Union Memorial Center. Oral and poster sessions will be scheduled in the North Ballroom, Rincon, Tucson, and Catalina rooms during all three days of EarthWeek.

EarthWeek provides an invaluable opportunity for students to share their research with peers, faculty, industry representatives, and the broader University of Arizona commu-nity. We welcome attendees from the University of Arizona, the Tucson community, and other academic institutions.

EarthWeek’s only cost of attendance, as always, is a love of the earth and environmental sciences. See you there!
