Welcome

Wearepleasedtowelcomeyoutothe45thannualGeoDaze!GeoDazeisaresearchsymposiumorganizedby volunteers from the Department of Geosciences that features groundbreaking research fromundergraduateandgraduatestudents.Eachyear,GeoDazeismadepossiblebygenerousdonationsfromindividualsandcorporatesponsors.Wesincerelyappreciateyourcontinuedsupport!

GeoDaze allows students to present their research to an enthusiastic audience of faculty, industryprofessionals,peers,andthegeneralpublic.Forthethirdyear,GeoDaze iscollaboratingwiththeotherdepartmentsintheSchoolofEarthandEnvironmentalSciencestobringyouEarthWeek.Inclusionwithinthis celebrationof scientific researchpromotes interdisciplinarydiscussion, collaboration,andexposurefor all of the participating departments. A full schedule of EarthWeek events can be found athttp://sees.arizona.edu/earthweek-2017.WeencourageyoutotakeadvantageofallthatEarthWeekhastooffer.

This yearGeoDaze isproud topresent31oraland23posterpresentations fromGeosciencesgraduateand undergraduate students. The diversity of these presentations is reflective of the Department ofGeosciences’ drive to integrate earth science research “from core to clouds”. They include research ineconomic geology, tectonics, geochemistry, geophysics, geomorphology, geoarcheology, paleoclimate,climate dynamics, mineralogy, geochronology, paleoecology, paleontology, and thermochronology. Inaddition, Simone Runyon has been selected to represent the Department of Geosciences in theEarthWeek Plenary Session with her talk, “Bottoms up: Deep alteration exposed in dismemberedporphyry copper systemsofArizona”, alongside representatives from theother SEESdepartments. TheplenarytalksareheldintheNorthBallroomfrom2:00-3:30pm,Wednesday,March29.

GeoDaze is proud to host Dr. Linda Rowan from UNAVCO as our keynote speaker. Dr. Rowan is theDirectorof ExternalAffairs atUNAVCO,where shehelps to advance geodetic-based research anddatasharingforsocietalbenefitandtobettercommunicatethebroaderimpactsofresearchanddevelopmenttothepublicat large.WeinviteyoutoattendDr.Rowan’spresentationentitled“Howtocommunicatethe valueof the geosciences to thepublic andpolicymakers” at 2:00 PMon Friday,March 31st in theNorthBallroom.

Inaccordancewithtradition,manyexciting“extracurricular”eventswilltakeplaceduringGeoDaze.Ourpanelof faculty judgeswillpresentawards to thebest talksandposters ineach sessionaswell as theoverall runner up and best talks.
