Extract

A description is given of an underwater camera unit mounted inside a high-speed tow-net body. The method of using this apparatus for surveying the seabed is described. The illustrations show that good quality results can be obtained when the camera is towed at speeds around 5 knots. By keeping the camera within a fathom from the bottom, satisfactory photographs can be obtained even where turbidity prevents photography at greater ranges.
