The EMSLAB Electromagnetic Sounding Experiment


  • EMSLAB Group


EMSLAB (Electromagnetic Sounding of the Lithosphere and Beyond)—Juan de Fuca is the largest electromagnetic (EM) induction experiment ever carried out. The two general objectives are to investigate the electrical structure of the lithosphere and asthenosphere beneath a complete oceanic plate and the adjacent continent under which it is subducted and to study tidal, mesoscale eddy, and other large-scale oceanic motions by measuring the electric currents induced in seawater as it moves in the geomagnetic field. More than 40 scientists, from 18 university and government institutions in the United States, Canada, Japan, Mexico, and Australia, are taking part.
