Figure F89. Magnetic field inclination determined by General Purpose Inclinometry Tool (GPIT) in the Formation MicroScanner (FMS)-sonic and Ultrasonic Borehole Imager (UBI) tool strings. Offset between different tool strings is caused by neighboring magnetized tool housings. Note that the International Geomagnetic Reference Field (IGRF11) inclination at Site U1374 is –52.2°.
