Project aboard

This study will collect temperature measurements in seafloor sediments offshore southern Mexico, and 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 and UNM; both are Hispanic-serving institutions. Two graduate students will be trained in geophysics and hydrogeology. Results of the project will be incorporated into using data in the classroom efforts, improving hands-on experience in undergraduate courses.
