EMAG2: Earth Magnetic Anomaly Grid

Magnetic anomaly maps allow us to look into the subsurface structure and composition of the Earth's crust. The magnetic variations in successive bands of ocean floor parallel to the mid-ocean ridges provide evidence of the temporal evolution of oceanic crust. The magnetic anomaly is important to the theory of seafloor spreading and plate tectonics.
