Figure F26. Schematic diagram illustrating the “antennae” effect experienced during Expedition 342 that channeled stray radio or electromagnetic field (EMF) from the core laboratory into the measurement region of the superconducting rock magnetometer (SRM). Illustration of the y-axis coil is redrawn from Oda and Shibuya (1996). SQUIDs = superconducting quantum interference devices.
