THIS PROPOSAL IS FOR FUNDS TO SUPPORT PARTICIPANTS TO ATTEND THE INTERNATIONAL GLACIOLOGICAL SOCIETY (IGS) SYMPOSIUM WHICH WILL BE HELD AT STANFORD UNIVERSITY ON 8 12 JULY 2019. THE THEME FOR THE SYMPOSIUM IS FIVE DECADES OF RADIOGLACIOLOGY . RADIO-ECHO SOUNDING IS A POWERFUL GEOPHYSICAL TECHNIQUE FOR DIRECTLY CHARACTERIZING THE SUBSURFACE CONDITIONS OF BOTH TERRESTRIAL AND PLANETARY ICE MASSES AT THE LOCAL REGIONAL AND GLOBAL SCALES. OVER THE LAST FIVE DECADES A WIDE ARRAY OF ORBITAL AIRBORNE TOWED AND IN SITU INSTRUMENTS PLATFORMS AND DATA ANALYSIS APPROACHES FOR RADAR SOUNDING HAVE BEEN DEVELOPED APPLIED OR PROPOSED. CONTINUING THE DEVELOPMENT OF RADIO-SOUNDING TECHNIQUES AND INSTRUMENTS IS PARAMOUNT TO OUR UNDERSTANDING ON SUBSURFACE CONDITIONS AND PROCESSES THAT INFLUENCE THE EARTH S CONTINENTAL ICE-SHEETS AND OTHER PLANETARY BODIES AND ICY MOONS. THE GOAL OF THIS SYMPOSIUM IS TO BRING TOGETHER TERRESTRIAL AND PLANETARY RADAR SCIENTISTS GLACIOLOGISTS GEOPHYSICISTS AND ICE-SHEET MODELERS TO DISCUSS ADVANCES IN (I) RADAR SOUNDING SYSTEMS (II) MISSION CONCEPTS (III) SIGNAL PROCESSING (IV) DATA ANALYSIS (V) MODELING AND (VI) SCIENTIFIC INTERPRETATION. WE EXPECT THAT THIS SYMPOSIUM WILL ATTRACT RADIOGLACIOLOGY EXPERTS WORKING IN ICE-SHEET ICE-SHELF MOUNTAIN GLACIERS AND PLANETARY ENVIRONMENTS AS WELL AS MODELERS AND OTHER GEOPHYSICISTS WHO ARE LOOKING TO APPLY AND UTILIZE RADIO-SOUNDING IN THEIR FIELD OF STUDY. USING THIS AWARD WE HOPE TO OFFER SUPPORT TO APPROXIMATELY 25 INDIVIDUALS MOST OF WHOM WILL BE EARLY CAREER SCIENTISTS. THIS PROPOSAL IS SUBMITTED THROUGH APPENDIX E.2: TOPICAL WORKSHOPS SYMPOSIA AND CONFERENCES (TWSC18) .
