Bureau of Fisheries vessels, such as the D. S. JOKPiM and prlvatfe ships under 

 contract with the Bureau and Philippine Naval vessels were used. The. radio=

Standard Hawaii techniques have been used throughout with many modifi- 

 cations^ mainly with respect to the holding of samples in the sampling bottles 

 until the vessels which were without 110 volt AC current aboard reached shore. 

 Delays or variations in technique that may have significantly altered results 

 from what they would have been under strictly "standard methods*' are indi= 

 cated by an "*" to the right of technique column 39. In general the same posi= 

 tions were sampled repeatedly In each of these two bays. Other data collected 

 with the productivity data mav be obtained from the FhlliTTrine Bureau of Fish- 

 eries . 



As a rule, sampling was done at Secchi disc depth, 2/5 Secchi disc 

 depth and at the surface. When the data bears the same location Information 

 at three depths it is an indication that this procedure v/as carried out.
