Ocean outfall dilution and dispersion measurements with horizontal and vertical profiling sensors

Investigation and analysis of the dilution and dispersion of waste water from an ocean outfall on the continental shelf is presented based on experimental measurements made by towed and cast sensor systems. Details of an experiment conducted at the Boca Raton, Florida, ocean waste water outfall in mid-December 1980 are presented. A vertical plane in the near wake of the outfall Was mapped using a Neil Brown CTD; a horizontal plane at a depth of one meter was profiled with a towed instrument platform housing a platinum resistance thermometer, a glass microbead thermistor and a high frequency fluorometer. The relevance of this data with respect to two mathematical models is discussed.
