A simple cartoon of the ocean’s motional inductance.



In 1832, the physicist famous for discovering electromagnetic induction equipped himself with a copper wire almost a thousand feet in length connected to a galvanometer and went to London’s Waterloo Bridge to see if the Thames River produced measurable electric currents. Unfortunately, after three days of work, Michael Faraday did not “obtain any satisfactory results.” Luckily, that was almost two centuries ago and geophysicists have come a long way since then. From voltage cables, seafloor or coastal magnetometer stations, and orbiting satellites, scientists have been able to detect the ocean’s electromagnetic pulse and use it to study many different aspects of the ocean and its subsurface.







Plus, Earth is not the only planetary body in the solar system with a salty ocean! The magnetic signals from Europa, Ganymede and Callisto’s subsurface oceans have also been detected via satellite.

OCEAN ELECTRODYNAMICS

I am a NASA Earth & Space Sciences Fellow interested in planetary magnetic fields and geomagnetic induction, as well as their applications for probing planetary interiors, exploring oceans, and monitoring natural hazards. I am a PhD Candidate at the University of Colorado Boulder.


I work within the NOAA/CIRES geomagnetism team, where my research focuses on investigating oceanic electromagnetic induction and isolating these signals. I am also a part of the ESA supported project "Magnetic Tidal Signals and Their Use in Mapping the Electrical Conductivity of the Lithosphere and Upper Mantle" (part of the Support to Science Element (STSE) Swarm+ Innovations).
