The phosphate and silicate samples were analyzed by spectrophotometric 

 methods at the NAVOCEANO chemical laboratory. Unfortunately, the 

 values obtained are questionable since the samples partially thawed 

 during shipment. There is no discussion of these data in this report. 



The physical and chemical oceanographic data were coded and forwarded 

 to NODC for processing by electronic computer. Machine computations 

 provided temperature, salinity, and dissolved oxygen interpolations 

 at standard depths, in addition to density (sigma-t) , specific volume 

 and dynamic depth anomalies, and sound velocity calculations. The 

 phosphate and silicate concentrations at observed depths were added 

 to the computation listings. Listings of these data are on file 

 at NODC under cruise reference numbers 31268 for January and 31216 

 for November-December. 



At the conclusion of both surveys the bottom sediment samples 

 were shipped to the Bureau of Mines facility at Tiburon, California, 

 where NAVOCEANO personnel analyzed them for engineering properties. 

 Sub-samples were for\i7arded to the NAVOCEANO geological laboratory 

 for sediment size and composition determination. Core analysis summary 

 sheets of engineering properties and sediment size and composition 

 are on file at NAVOCEANO under Laboratory Item 227 for January and 

 Item 242 for November-December. The grab sample and the two parts 

 of cores from the January survey were not analyzed. Log sheets of 

 the bottom sediment data from both surveys are presented in the 

 appendix. Since bottom sediment distribution has been amply covered 

 by other works (e.g., Emery, 1960). The sediment data are not 

 discussed in this report. 



The BT data are on file at NODC under reference number 08382 

 for January and 08383 for November-December. 



Results from the drift card releases have not been obtained. 



At NAVOCEANO, the plankton samples were filtered through cotton 

 cloth. The volume of each wet sample was read in a graduated cylinder 

 and water added to the lOOcc level. Aliquots of 2cc were drawn while 

 stirring the sample. A sufficient number of aliquots were removed 

 to include 4 to 20 percent of the sample, depending on the total 

 volume of plankters involved. The type and number of plankters from 

 the January and November-December surveys are tabulated in the appendix. 



Parachute current drogue tracks were plotted and are included 

 in this report. Average velocities were computed to the nearest 

 tenth of a knot for each observation interval. Current drogue summary 

 sheets are presented in the appendix.
