Short summary
Marine electromagnetic (EM) signals largely depend on three factors: the direction and speed of ocean flow, the strength of Earth’s main magnetic field, and seawater’s electrical conductivity (which depends on the local temperature and salinity). Because of this, there is interest in using marine EM signals to monitor and study ocean circulation. Our study investigates using voltage data from retired seafloor telecommunication cables in the Pacific Ocean to monitor large-scale flows.
