This survey will combine controlled-source electromagnetics (CSEM) with passive magnetotellurics (MT) to provide a comprehensive picture of the electrical conductivity structure from the seafloor to the upper mantle, representing the

2 entire input into this part of the Central American subduction zone. A 300 km profile will be collected offshore Nicaragua and another smaller profile will be collected offshore the Nicoya Peninsula, Costa Rica. In addition to the societal relevance of improving our understanding of processes that produce convergent margin earthquakes and volcanic eruptions, this project will support two Ph.D. students.
