This paper describes how the well-known MTF theory and experimental technique can be employed to monitor suspended particulates in the aqueous environment by using instrumentation that rivals the Secchi disk in simplicity, but which has many advantages over this older method. The design of a simple low-cost underwater camera-light source-target system is reported and its use is demonstrated by observing the temporal variation in the transparency of Biscayne Bay water during the passage of a barge-tug vehicle. /Author/
