salinometers. Duplicate water samples were 

 drawn from the surface and 1500 meter Nan- 

 sen bottle at each station and delivered to the 

 Coast Guard Oceanographic Unit for quality 

 control when the vessels returned to port. 

 These samples were run by a different operator 

 and on a different instrument and it was found 

 tViat, on the average, 89 percent of the samples 

 differed from the ship's values by less than 

 O.OlOo/no. The samples were higher in salinity 

 than the ship's values by an average of only 

 .004 %o after about a month's period. 



Processed temperature and salinity data 

 were recorded on form NODC-EXP-3167/25 

 (3-64), Physical and Chemical Data form for 

 oceanographic stations and delivered to the 

 National Oceanographic Data Center (NODC) 

 for archiving and the preparation of listings. 

 The interpolated temperature and salinities for 

 standard depths, sigma-t values, geopotential 

 anomalies (AD) and sound velocities were 

 computed by NODC and listings provided for 

 the preparation of Tables I-XI. 



CRUISE NARRATIVES 



The CGC KLAMATH occupied 17 oceano- 

 graphic stations during her 20 March— 8 April 

 1967 patrol. The majority of the casts had 

 maximum useful depths between 1350 and 1950 

 meters. Two casts had maximum sampling 

 depths of 1113 and 1123 meters due to ex- 

 tremely large wire angles. One deep cast was 

 accomplished, with a maximum sampling 

 depth of 3778 meters in a water depth of 4389 

 meters. One shallow station has no salinity 

 values due to an error by the operator of the 

 salinometer. Four stations were occupied 90 

 miles south of O.S. NOVEMBER grid. The dis- 

 tribution of the other 13 stations about the 

 center of NOVEMBER is shown in figure 3. 

 The data are listed by NODC as Ref. No. 

 31-1079 and as Table I in this report. 



The CGC KLAMATH also occupied a line of 

 18 oceanographic stations from Ocean Station 

 NOVEMBER to the coast of Oregon on the re- 

 turn trip to port. These stations make up a 

 portion of Standard Monitoring Section 4 and 

 the data will be published at a later date. The 

 data are also listed by NODC as Ref. No 31- 

 1079. 



During the period 2-19 May 1967, the CGC 



PONTCHARTRAIN occupied 17 oceanographic 

 stations on Ocean Station NOVEMBER. The 

 majority of the.se stations had maximum useful 

 sampling depths between 1400 and 1700 meters. 

 One cast reached only to 991 meters due to a 

 very large wire angle. One deep cast was ac- 

 complished with a maximum sampling depth of 

 3669 meters in a water depth of 4114 meters. 

 Four stations were taken 90 miles south of 

 NOVEMBER and the distribution of the other 

 13 stations about the center of NOVEMBER 

 is shown in figure 4. The data are listed by 

 NODC as Ref. No. 31-1080 and as Table II of 

 this report. 



The CGC PONTCHARTRAIN also occupied 

 11 stations on Standard Monitoring Section 6 

 on the return voyage from O.S. NOVEMBER. 

 The data are also listed by NODC under Ref. 

 No. 31-1080 but will be published at a later 

 date. 



The CGC WINONA successfully occupied 17 

 oceanographic stations during the 15 June-1 

 July 1967 patrol on Ocean Station NOVEM- 

 BER. All seventeen stations had maximum 

 useful depths between 1350 and 1650 meters. 

 No deep cast was accomplished as the ship 

 had difficulties with the winch brake. One sta- 

 tion was taken 90 miles south of Ocean Station 

 NOVEMBER and the distribution of the other 

 16 about the center of NOVEMBER is shown 

 in figure 5. The data are listed by NODC as 

 Ref. No. 31-1083 and as Table III in this re- 

 port. 



The entire 24 stations of Standard Monitor- 

 ing Section 4 were occupied by the CGC WI- 

 NONA on the return trip from NOVEMBER. 

 These data are also listed by NODC as Ref. No. 

 31-1083, but will be published at a later date. 



The CGC PONTCHARTRAIN successfully 

 occupied 21 oceanographic stations during the 

 23 July-13 August patrol at Ocean Station 

 NOVEMBER. All casts except one had maxi- 

 mum useful depths of between 1400 and 1530 

 meters. The one exception was to only 1296 me- 

 ters due possibly to a large subsurface current. 

 This station was taken 90 miles south of Ocean 

 Station NOVEMBER, as were two other sta- 

 tions. The distribution of the other stations 

 about the center of NOVEMBER is shown in 

 figure 6. One deep cast was accomplished, with 

 a maximum sampling depth of 4400 meters in
