BECAUSE TIDAL ACTIVITY IS ENHANCED BY THE PRESENCE OF A SUBSURFACE OCEAN IDENTIFICATION OF TECTONIC FEATURES FORMED FROM TIDES HAS IMPLICATIONS ON THE PRESENCE OF SUBSURFACE LIQUID WATER OCEANS AND THE HABITABILITY OF OUR SOLAR SYSTEM AND SYSTEMS AROUND OTHER STARS. TO DETERMINE THE EXTENT TO WHICH THE TECTONIC RECORDS OF ICY SATELLITES LIKE EUROPA AND ENCELADUS SUPPORT LIQUID WATER OCEANS WE MUST BETTER UNDERSTAND HOW TIDAL-TECTONIC PROCESSES OPERATE. TO ACCOMPLISH THIS WE WILL:1) ANALYZE OUR CURRENT GPS DATA IN ORDER TO FURTHER CHARACTERIZE DAILY MOTIONS ALONG AN ANTARCTIC RIFT THAT IS UNBOUND AT ONE END.2) OBTAIN NEW OPS/SEISMIC DATA ALONG AN ANTARCTIC RIFT THAT BOUND WITHIN THE ICE SHELF MORE ANALOGOUS TO FRACTURES ON EUROPA AND ENCELADUS.3) ANALYZE OUR NEW GPS DATA IN ORDER TO CHARACTERIZE DAILY TIDAL MOTIONS ALONG THE NEW ANTARCTIC RIFT AND CONSTRAIN THE MAGNITUDES OF TIDAL MOTION ON EUROPA AND ENCELADUS.4) ANALYZE OUR NEW SEISMIC DATA IN ORDER TO EXPLORE THE RELATIONSHIP BETWEEN OBSERVED SURFACE SLIP AND THE RELEASE OF ENERGY ALONG THE RIFT.
