postseason cruise it was established by a 

 NAVOCEANO engineer that all of the preced- 

 ing troubles were caused either by the Marsh- 

 Marine connector leaking at the boot end of 

 the female connector or the conductor breaking 

 in the sea cable at the first point above the 

 underwater equipment rack where flexing could 

 occur. This point is illustrated in Figure 5A. 

 The leaking connector was repaired by securely 

 taping the upper part of the connector with 

 a good grade of self-vulcanizing rubber tape 

 and then covering this with black plastic tape. 

 Both surface and sub-surface salinity sam- 

 ples and temperature measurements were taken 

 to insure that the STD was indicating the 

 correct temperature and salinity. Both Nansen 

 and STD casts were made at stations along 



Table I. Comparison of Dynamic Heights computed us- 

 ing data from duplicate STD and Nansen casts 



Section 2 and dynamic heights were calculated 

 using both sets of data. The duplicate casts 

 along Standard Section 2 plus comparison from 

 two additional stations are presented in Table I. 

 Figure 5B shows the STD trace obtained 

 for Station 9592 plus the temperature and 

 salinities obtained from a Nansen cast taken 

 50 minutes later. It shows considerable varia- 

 tion between the two sets of data, but the dy- 

 namic heights calculated from each differ by 

 only 0.009 dynamic meters. Such good agree- 

 ment, even with such large salinity changes, 

 indicates that dynamic heights computed from 

 STD data are compatable with the dynamic 

 heights computed using Nansen cast data, par- 

 ticularly when the rate of change of salinity 

 is small. 



Personnel 



The oceanographic work of the first cruise 

 was under the direction of LCDR Ronald C. 

 Kollmeyer, USCG who was assisted by LCDR 

 Kennard M. Palfrey, Jr., USCG and LTJG 

 Melvin S. Swanson, USCGR. Mr. Thomas 

 Wolford, Oceanographer, directed the second 

 cruise assisted by LCDR Kennard M. Palfrey, 

 Jr. Because of special instruction and experi- 

 ence with the STD, James D. Brower, Aero- 

 graphers Mate Second Class assisted during 

 both cruises. Other oceanographic technicians 

 for the first cruise were David D. Lockhart, 

 Aerographers Mate First Class; John T. 

 Nichol, Sonarman Second Class; David J. 

 Wood, Sonarman Second Class; and Edward 

 S. Olszewski, Sonarman First Class. Technical 

 Assistants for the second cruise were Dennis 

 L. Noble, Chief Aerographers Mate; William 

 L. Harrel, Sonarman First Class; and Peter 

 R. San Jule, Aerographers Mate Second Class.
