| Summary: | In 1965 researchers from the Lamont Geological Observatory aboard the USSEltanincollected magnetic data from the seafloor of the Pacific-Antarctic Ridge. These data were digitally processed and inscribed in the form of magnetic anomaly profiles. A magnetic profile is a line graph that demonstrates the remnant magnetism recorded by a magnetometer towed by a ship or by a plane traversing a specific path. Magnetic profiles are essentially cross sections of magnetic anomaly maps; this relationship is clearly demonstrated in figure 7.9. One of the Lamont group’s magnetic profiles—Eltanin19—would become the most important piece of geophysical evidence |
