ships. While this in practice may be hard to achieve, nevertheless definite considera- 

 tion should be given to establishing comparison at some other point, rather than the 

 surface of the ocean. 



Another approach to the problem would be to establish whether the Bathyther- 

 mograph reads an average value of the first few feet or an actual value. If the 

 former is true, then some means should be made for obtaining an average bucket 

 sample rather than a superficial surface sample. Improving the sampling conditions 

 might well be the answer to increased accuracy in establishing Bathythermograph 

 corrections.
