the section lasted through 24 May and con- 

 sisted of stations 9954-9988. The STD failed 

 on station 9980. On 30 May another iceberg- 

 drift project began, and this lasted through 4 

 June when CGC EVERGREEN started the 

 final calibration survey of the season. This 

 calibration survey lasted through 7 June and 

 consisted of stations 9997-10023. On 7 June 

 CGC EVERGREEN set sail for Boston, her 

 operational ice patrol duties finished. 



The research cruise was to have consisted 

 of standard sections 1 and 4 and an iceberg- 

 drift project. However, due to a thrust bearing 

 failure, the cruise only occupied standard sec- 

 tion 4 from 25-28 July with stations 10024- 

 10040. 



Additional Projects 



The iceberg drift and deterioration project 

 was continued in the spring of 1967 with 

 studies on four icebergs over time intervals 

 ranging from about 1 to 4 days on 13-14 April, 

 19-21 April, 16-19 May and 30 May to 4 June. 

 The CGC EVERGREEN tracked the icebergs 

 and deep and shallow drogues with reference 

 to an anchored buoy, photomapped the icebergs, 

 and recorded wind data. These data will be 

 compiled and published in a separate report. 



Personnel 



The oceanographic work of the first cruise 

 was under direction of the Field Party Chief, 

 LCDR Kenneth M. Palfrey, USCG. Members 

 of the Field Party were Chief Aerographer's 

 Mate Dennis L. Noble, Sonarman First Class 

 Edward S. Olszewski, Jr., Aerographer's Mate 

 First Class David D. Lockhart, Sonarman Sec- 

 ond Class Curtis D. Gelder, Sonarman Second 

 Class John G. Colantoni, and Aerographer's 

 Mate Second Class Michael J. Sundquist. The 

 Field Party Chief for the second cruise was 

 Mr. Thomas C. Wolford, Oceanographer. Mem- 

 bers of the Field Party were Sonarman First 

 Class William T. O'Brien, Aerographer's Mate 

 Second Class Peter R. San Jule, Aerographer's 

 Mate Third Class Kenneth D. Thoeni, Seaman 

 Aerographer's Mate Raymond M. Patmos, Sea- 

 man Aerographer's Mate Danny L. Allen and 

 a student trainee, Mr. Donald P. Massa. The 

 Research Cruise was also under the direction 

 of Mr. Thomas C. Wolford, who was assisted 



by Lieutenant James M. Seabrooke, USCG. 

 The Field Party consisted of Senior Chief 

 Sonarman Robert C. Reid, Sonarman Second 

 Class Curtis D. Van Gelder, Sonarman Second 

 Class John G. Colantoni, Yeoman Second Class 

 Dwight E. Olson, and a student trainee, Mr. 

 Richard F. Johnson. 



Instrumentation 



The primary sampling instrument for the 

 stations occupied during the 1967 cruises was 

 a Bisset-Berman Model 9006N salinity/tem- 

 perature/depth (STD) recorder. The readings 

 of the STD were corrected by comparison with 

 Nansen bottle samples taken on the STD wire. 



The teflon-lined Nansen bottles used were 

 from Ballauf Manufacturing Co. and United 

 Machine Co. The deep sea reversing ther- 

 mometers were manufactured by Richter and 

 Wiese, GM Manufacturing Co., Kahl Scientific 

 Instrument Corp., and Walter H. Kessler Co., 

 Inc. The bathythermograph system used was 

 the Sippican Corp. expendable BT. A model 

 6220 Bisset-Berman salinometer determined 

 salinities of water samples taken by Nansen 

 casts. 



The following presents a summary of rep- 

 resentative statistics on the salinity and tem- 

 perature instruments:

3 Morse (1963).

An Alpine Precision Echo Sounder Recorder 

 was used to measure depth to the bottom. A 

 near surface temperature recorder installed 

 on the CGC EVERGREEN was erratic in op- 

 eration when compared with other means of 

 obtaining sea surface temperature. One of the 

 problems was that the sensor was located in a 

 sea chest.
