Abstract
A method and apparatus for conducting a survey to determine the location and elevation of a buried pipeline located in a shallow water environment. The method includes determining whether submerged obstacles are located between the ends of that portion of the line being measured and measuring the depth of the line by taking magnetic sounding of the buried line at spaced intervals by crossing the line at longitudinally spaced points with the magnetic survey apparatus. The apparatus includes a towed sled for carrying the magnetic sensing device.
