EXPLANATION OF DATA TABLES 



Table 1. — Summary of station observations. 

 Hydrographic stations have the prefix 

 "H", while productivity stations are num- 

 bered independently and have the prefix 

 "P". Time entries at productivity stations 

 are times of initial water collection. Time 

 entries at hydrographic stations are times 

 of first messenger release. All times are 

 to the nearest 5 minutes and are Pacific 

 Standard Time (PST: +8 zone). 



Table 2. — Tabulated hydrographic station data. 

 Time entries are times of first messenger 

 releases on each cast and are GCT. Mes- 

 senger times and wire angles are given 

 in order of increasing depth when more 

 than one cast was made on a station. A 

 line is left blank between observed data 

 of each cast. 



To indicate degree of accuracy, tempera- 

 tures are recorded in tenths of a degree 

 Celsius (C.) when obtained by bucket 

 thermometer or bathythermograph while 

 temperatures from reversing thermome- 

 ters are recorded in hundredths of a degree 

 C. Extrapolated values and values inter- 

 polated between widely spaced observa- 

 tions are entered in parentheses. Hyphens 

 indicate missing observed values. 



Table 3. — Bathythermograph observations. 

 Observations presented in accordance with 

 H.O. Publication No. 606-c(1956). Lower- 

 ings to 450 ft, are indicated by post- 

 script "a" after the slide number. All 

 other lowerings were made to 900 ft. 

 Observations made at hydrographic sta- 

 tions are indicated in the last column by 

 the station number. Between -station BTs 

 are indicated by hyphens in that column. 



Table 4. — Solar radiation measurements. 

 Integrated values are given for morning 

 and afternoon to allow better compari- 

 sons between productivity measurements. 



Values in parentheses are approximate 

 because of occasional recorder pen diffi- 

 culties. 



Table 5. — Surface C^"* productivity measure- 

 ments. Time entries are times of water 

 collection and are PST (+8 zone). Values 

 in parentheses are questionable by virtue 

 of either slow filtration or damaged filter. 

 These values are not included in station 

 averages or in figure 4, 



Table 6. — Surface chlorophyll a measure- 

 ments. Time entries are times of initial 

 water collection and are PST (+8 zone). 

 Values in parentheses are questionable 

 by virtue of either slow filtration or high 

 optical density at 750 m/i wave length. 

 These values are not included in station 

 averages or in figure 3. 



Table 7. — Zooplankton collection data. Time 

 entries are PST (+8 zone). Volume of 

 water recorded is here considered to be 

 volume of water strained by the net 

 although no corrections for net resistance 

 or clogging have been applied to calibra- 

 tions of the meter. Zooplankton displace- 

 ment volume is the drained wet volume of 

 organisms captured, after removal of 

 organisms whose volume exceeds 

 5 cm. 3. 



Table 8. — Relative abundance of zooplankton 

 organisms. Taxa in parentheses are tenta- 

 tive identifications. The author is re- 

 sponsible for these and other identifica- 

 tions. 



Table 9. — Trolling results. Time entries are 

 PST (+8 zone). 



Table 10. — Gill net results. Time entries are 

 PST (+8 zone).
