6. SOLUBLES 



A. H. Woodcock 



Among the many processes and events occurring in the surface waters of the 

 sea is the momentary trapping of air in the form of bubbles. These bubbles 

 range in size from a few millimeters to several microns in diameter. They 

 result in major part from meteorologically induced disturbances, such as the 

 breaking of wind-waves, the impact of raindrops and the melting of snow and 

 hail (Blanchard and Woodcock, 1957),
