Deep Tow
Deep Tow : (n.) Geophysics. A method of marine seismic acquisition in which a boat tows a receiver well below the surface of the water to get closer to features of interest or to reduce noise due to conditions of the sea. Deep tow devices are used for some side-scan sonar, gravity and magnetic surveys. See: Acquisition, Gravity, Gravity Survey, Magnetics, Noise, Seismic Acquisition, Side-Scan Sonar
