POLLUTANT DEBRIS - Floating solid objects to be removed or excluded from 

 an area. 



POLLUTANT DISPERSION - Chemical treatment of a floating liquid pollutant 

 to break up its slick and cause it to become emulsified witb water. 



POLLUTANT MEASUREMENT - Detection, identification, sampling, or measure- 

 ment of marine pollutants, such as 'oil slicks, turbidity, or gases, 

 by field equipment. 



POLLUTANT REMOVAL WATERCRAFT - A navigable craft, usually a barge, 

 equipped vith apparatus for removing marine pollutants. 



POLLUTANT, MECHANICAL REMOVAL - Removal of pollutants from the surface 

 of a body of water by the use of rotating drums, conveyors, belts, 

 or scoops. 



POLLUTANT, SUBMERGED BARRIER - A barrier preventing the spread of pollu- 

 tants from submerged leaks. 



POLLUTANT, SUCTION REMOVAL - Removal of pollutants by pumping them 



directly from the surface of a body of water or from a collection 

 barge, including the use of weirs to control the intake flow. 



POLLUTANT, SURFACE BARRIER - A barrier preventing the spread of floating 

 pollutants, usually a floating boom. 



POWER, SUBMERGED SOURCE - A means of extracting power from ocean currents 

 or from pressure or thermal gradients to drive electrical generators 

 or samplers* 



POWER, TIDE - A means of extracting power from impounded tidal flow, 



tidal currents, or the tidal rise and fall of the water's surface to 

 drive electrical generators, pumps, or mechanical devices. 



POWER, WAVE - A means of extracting power from wave motion to drive 

 electrical generators, pumps, mechanical . devices , or instruments. 



PUMP - A means of moving a fluid or slurry under pressure, usually part 

 of a dredge or means of extracting power from the ocean. 



REVETMENT - A facing of stone, concrete blocks, grout-filled fabric mats 

 or bags, or other material, built to protect a scarp, embankment, or 

 shore structure against erosion by wave action or currents. 



SALINITY MEASUREMENT - Determination of the salinity, conductivity, or 

 acidity of water by field equipment. 



SAMPLER, BIOTA - A means of collecting specimens of sea plant or animal 

 life.
