Seafloor magnetotelluric sounding above axial seamount
Geophysical Research Letters, 1996 Axial Seamount is a large, active, ridge axis volcano located on the central segment of the Juan de Fuca Ridge in the northeast Pacific Ocean. Magnetotelluric (MT) data have been collected at three sites, approximately 4 km apart around the eastern rim of the volcano, during a 65‐day deployment.
