Overall, this study is designed to detect if hydrothermal circulation is present within oceanic crust just prior to entering the Cascadia subduction zone, offshore Oregon and Washington. The project will collect seismic reflection data and temperature data in seafloor sediments offshore Washington and Oregon, map the distribution of those sediments, to understand the controls on temperatures in the system and improve estimates of subduction zone temperatures. The results of this research have direct societal benefit, by informing earthquake hazard estimates. In addition, the proposed project will enhance education at New Mexico Tech, a STEM-focused Hispanic-serving institution. Two graduate students will be trained in geophysics and hydrogeology. Results of the project will be incorporated into classroom studies improving hands-on experience in undergraduate courses.
