a water depth of 4663 meters. The data are 

 listed by NODC as Ref. No. 31-1142 and as 

 Table IV of this report. 



The CGC PONTCHARTRAIN also partici- 

 pated in cooperative deep current observations 

 conducted by personnel from the Scripps Insti- 

 tution of Oceanography. Two free-vehicle type 

 current meters were used for six separate 

 drops with five recoveries. The current meter 

 array consisted of a fiberglass-aluminum pole 

 with float connected by a nylon line to a sec- 

 ondary float to which was connected the current 

 meter instrument and ballast weight. Each 

 pole-float contained a radio beacon, battery and 

 antenna, a radar reflector, and a bright orange 

 flag. Little or no success was experienced with 

 the radio beacons and radar reflectors. The most 

 valuable recovery aid turned out to be the 

 bright orange flag, which was sighted up to 31/2 

 miles distant. The current observations are 

 retained by the Scripps Institution of Ocean- 

 ography, La Jolla, California. 



The CGC PONTCHARTRAIN again was as- 

 signed to Ocean Station NOVEMBER patrol 

 for the period of 30 August-29 September 

 1967. During this period 20 oceanographic sta- 

 tions were occupied. All twenty stations had 

 maximum useful depths between 1400 and 

 1630 meters. One deep cast was accomplished, 

 with a maximum sampling depth of 3265 me- 

 ters in a water depth of 3749 meters. One sta- 

 tion was occupied 60 miles south of Ocean Sta- 

 tion NOVEMBER and one 90 miles south ; the 

 distribution of the other stations about the cen- 

 ter of NOVEMBER is shown in figure 7. The 

 data are listed by NODC as Ref. No. 31-1163 

 and as Table V of this report. 



In cooperation with the Scripps Institution of 

 Oceanography, six free-vehicle current meters 

 were launched during this patrol and five re- 

 covered. Approximately 630 hours of bottom 

 current observations were obtained. These data 

 are retained by the Scripps Institution of 

 Oceanography, La Jolla, California. 



The CGC PONTCHARTRAIN also occupied 

 the entire 24 stations of Standard Monitoring 

 Section 6 on the return trip to port. These data 

 are also listed by NODC as Ref. No. 31-1163, 

 but will be published at a later date. 



There was an interesting occurrence on the 



ship's first attempt at a deep cast on Ocean 

 Station NOVEMBER. A miscalculation was 

 made in the depth of water to the bottom and 

 500 meters of cable were laid on the bottom. 

 When the cast was retrieved, a large boulder, 

 weighing approximately 240kg. and with di- 

 mensions of about 36 inches in height and 

 about 24 inches in breadth, was entangled in 

 the cable and was brought to the surface. The 

 specimen was subsequently given to the 

 Scripps Institution of Oceanography for analy- 

 sis and was identified as an extremely large 

 manganese nodule, (see frontispiece). 



During the 15 October-8 November patrol of 

 the CGC TANEY on Ocean Station NOVEM- 

 BER, a total of 21 oceanographic stations were 

 occupied. With the exception of one cast, all 

 casts had maximum useful depths between 

 1450 and 1650 meters. One station had a maxi- 

 mum sampling depth of only 552 meters due to 

 the failure of a Nansen bottle to release its 

 messenger. One deep cast was accomplished, 

 with a maximum sampling depth of 4270 me- 

 ters in a water depth of 4390 meters. This dis- 

 tribution of the stations about the center of 

 NOVEMBER is shown in figure 8. The data 

 are listed by NODC as Ref. No. 31-1178 and as 

 Table VI of this report. 



The CGC TANEY also occupied 19 oceano- 

 graphic stations on Standard Monitoring Sec- 

 tion 5 on the return trip NOVEMBER. These 

 data are also listed by NODC as Ref. No. 

 31-1178, but will be published at a later date. 



The CGC KLAMATH occupied 13 oceano- 

 graphic stations during the 26 November-17 

 December 1967 patrol on Ocean Station NO- 

 VEMBER. All stations had maximum useful 

 depths between 1350 and 1950 meters. One 

 deep cast was accomplished, with a maximum 

 sampling depth of 3891 meters in a water 

 depth of 4244 meters. The distribution of the 

 stations about the center of NOVEMBER is 

 shown in figure 9. Two stations were occupied 

 approximately 60 miles south of Ocean Station 

 NOVEMBER. The data are listed by NODC as 

 Ref. No. 31-1185 and as Table VII of this re- 

 port. 



The CGC TANEY occupied 21 oceano- 

 graphic stations during the 7-28 January 1968 

 patrol at Ocean Station NOVEMBER. With
