vithin the envelope of the Equatorial Water Mass and is much less 

 influenced "by Arabian Sea water although it still shows up as a 

 salinity maximum. The third station in a north-south direction is 

 located in a transition area where Indian Central Water is present 

 above the Equatorial water. The next three stations farther south 

 are located within the Central Water Mass; however^ these stations 

 also present a salinity maximum where Arabian Sea Water comes in at 

 greater depths. The four southernmost stations are located south of 

 the Mozambique Channel and Arabian Sea Water appears only as a 

 slight salinity maximum at about 1,500 meters on all but the 

 southernmost station. The deep water at these four stations also 

 shows a salinity maximum in the deep water greater than "^k. 80 %c, 

 ■which is caused by the influx of Atlantic Deep Water. 



The central section HH' is taken in a north-south direction 

 through the central part of the Indian Ocean and the station locations 

 are given in Table 8. The northernmost station is located within the 

 Equatorial Water Mass and all other stations except the two southern- 

 most stations are within the Indian Ocean Central Water. The two 

 southernmost stations are located south of ij-5°S latitude and there- 

 fore are south of the Subtropical Convergence. The Indian Ocean 

 Central Water is absent at these two stations and the Antarctic 

 Intermediate Water is present at shallow depths. The salinity maxi- 

 mum in the deep water of this section appears to be about 3^-75^ 

 which is considerably less than in the western section where Atlantic 

 Deep Water is present. 



The eastern section JJ' extends in a northwest to southeast 



direction and shows the great uniformity of the Central Water Mass 



in the southeast Indian Ocean. Station locations are given in
