Abstract : A survey of the Marine Physical Laboratory deep tow instrumentation system is presented. Included are descriptions of the development and implementation of the hardware, instrumentation, and techniques involved in the use of this deep towed submersible instrument platform for oceanographic research. The system is equipped with up-, down-, forward-, and side-looking sonars, as well as low-frequency (rkHz) bottom penetrating sonar, proton precession magnetometer, precision temperature probe, stereo cameras and strobe light, and snapshot television. Control information and data are telemetered along the supporting coaxial cable bilaterally between the fish near the bottom and the laboratory aboard ship. Precision navigation of both fish and ship is accomplished by means of a network of acoustic transponders. Since its initial usage in late 1964, the system has been in operation for over 10,000 hours in depths down to and exceeding 7000 meters. (Author)
