Method and apparatus for detecting the presence of hydrocarbons and other substance that fluoresces or absorbs light within a body of water which utilizes a controlled submersible vehicle scanning at or near the water bottom. The method utilizes a selected frequency light source as carried by the submersible to scan the water bottom, and the returned light energy, either at the wavelength of oil fluorescing in water or the source frequency backscatter, is detected and processed for the water b o t t o m as well as a water region that is a selected distance above the water floor. Alternative forms of apparatus are disclosed for carrying out the functions of both oil fluorescence detection, and for obtaining differential absorption readings as to light source backscatter energy that is created by the ambient water and other factors in the water environment such as marine life, turbidity, etc.
l h e invention involves a device for utilizing the energy from sea swells and waves, l h e device is characterized by the combination of: ( a ) a \essel adapted to follow the regular undulations of sea swells at a place of anchorage, and constructed in a manner to face the swells so as to pitch and not to roll while anchored; (b) air cylinders disposed at least at one extremity of the vessel to moderate more or less the amplitude of the pitching: (ci watertight compartments containing a liquid: (d) prime movers, such as continuously powered ltlrbines, located in the path of the liquid and suited to harness energy from the liquid as it moves so as to supply mechanical energy to at least one ,:otatable shaft; and (e) liquid deflectors located at the extremities of each water-tight compartmenL

the aeration chamber flows upwardly and the filters are connected at the top by a crossover pipe positioned below the top level of sludge in the aeration chamber. The crossover pipe communicates with a vertical riser which functions with a vertical antisyphon vent. The riser communicates with a flexible hose which connects the primary central aeration chamber with the chlorine contact tank to receive the sludge from the biological filters for chlorinating the liquid and providing an adequate retention time for disinfection prior to discharge overboard.
