Abstract:

A proton precession magnetometer has been developed to measure the geomagnetic field intensity at the ocean floor. The instrument was built on short notice to support the search for the SSN Thresher and was operated at a depth of 1300 fathoms while being towed at two knots. A promising magnetic contact was made and verified by two subsequent crossings during about one hundred hours of operation and the instrument was not used further. A brief description of the instrument construction and operation is presented and some salient design features of the electronics and deep-towed vehicle are discussed and illustrated. Author
