ABSTRACT 



A brief introduction is given of oceanography for acousticians. The 

 main topics and related acoustical examples are: submarine geology (bottom 

 acoustic loss) ; marine biology (the deep sound scattering layer) ; chemical 

 and physical properties of seawater (sound speed and sound absorption) ; 

 the steady state of the ocean (sound speed vs depth structure and modes of 

 sotind propagation in the ocean) ; and waves in the ocean (sea surface loss 

 and sea surface noise, and acoustic propagation and internal waves).
