Note: Before the use of the gyro compass, the earth's magnetic field caused major navigational errors. From 1909 to 1929 the seagoing observatory Carnegie set out to conduct international surveys of magnetic, electric, and oceanographic activity on land and water to locate and finely measure the then unknown magnetic influences. The Carnegie Institution in Washington D.C. built the ship designed by Henry J. Gielow, a New York naval architect. It was designed to be built from special nonmagnetic materials, from the timbers, metal bolts, and cables, down to the stove and eating utensils, so that they wouldn't affect the magnetometers.
