|North Cascades Geology: Sea-Floor Spreading|
This site contains information about discoveries made after World War II when ocean-going geologists adapted sensitive magnetometers developed for antisubmarine warfare for use in seafloor research. This modern technology gave geologists their greatest boost in more than a century of field work and led to the idea of sea floor spreading. This site has animations showing sea-floor spreading and a magnetometer discovering magnetic strips. There are also diagrams showing the magnetic pattern on the ocean floor at the Juan de Fuca Ridge, Benioff-Wadati zones at continental margins, and an idealized representation of divergent plates with a resulting subduction zone.
