Research in acoustic scattering was 

 carried out at the tower by officer stu- 

 dents of the Navy Postgraduate School, 

 Monterey. Measurements at varying 

 depths, frequencies, and times provided 

 data on the size and distribution of 

 scattering particles in the water. These 

 data were used for thesis material. 



Postgraduate School students employed a variable- 

 depth electrostatic transducer which transmitted 

 signals over a 3-octave band (24 to 192 kc/s). It 

 determined the presence and distribution of scatterers 

 in the water column.
