floating gauges. References VII-14 and VII-26 contain discussions of 

 some bottom, floating, and fixed gauges not covered in this Section; in 

 addition, Reference VII-14 contains a discussion of the Sonne three 

 dimensional aircraft camera. 



2. Bottom pressure instruments 



Various bottom pressure instruments are discussed by References 

 VII- 12, -13, -14, -16, -20, -21, -22, -23, -24, -25, -26, -30, -31, and 

 -34. 



3. Floating wave gauges 



Part C,2 of this Section discusses and references several float- 

 ing wave gauges. These gauges are covered in greater detail by Refer- 

 ences VII-6, -8, -27, -29, and -32. References VII-14, -21, -26, and 

 -31 also contain articles on various floating gauges. 



4. Fixed wave gauges 



Part C,3 of this Section briefly discusses several fixed wave 

 gauges. These and other gauges are discussed in greater detail by 

 References VII-1, -2, -3, -7, -9, -14, -17, -18, -26, and -35. No pub- 

 lished information is available for the resistance wire wave staff 

 of the Hydrographic Office. 



5. Airborne wave measuring techniques 



Two methods of airborne wave measurement other than the 

 Sonne camera are discussed by References VII-5 and VII- 19.
