C . Gulf of Oman and the Arabian Sea 



During February and March 1961, 62 oceanographic stations were obtained 

 in the Gulf of Oman and the Arabian Sea (Fig . 3) . 



Temperature-Salinity curves for representative stations in the Gulf of Oman 

 and the Arabian Sea (Figs. 9, 11, and 19) show the influence of the Persian Gulf 

 water between 150 and 300 meters . The most significant feature of the curves is 

 the uniform water mass below 500 meters . Figure 9 also includes stations 42 and 

 43 (Fig . 2) taken in January as a part of the lower Persian Gulf and Strait of 

 Hormuz survey. 



A salinity profile from station 3 in the Gulf of Oman southeast to station 50 

 then to the Bay of Cambay (Fig. 12) shows the influence of the high salinity Persian 

 Gulf water between 150 and 300 meters as well as the low salinity Bay of Cambay 

 water penetrating the Arabian Sea surface water. 



Surface temperatures recorded in the Gulf of Oman and the Arabian Sea ranged 

 between 23.77°C. in the northwest to 26.76°C. in the southeast, while surface 

 water samples analyzed ranged in salinity between 34.90% in the Bay of Cambay 

 to 36.58% in the Gulf of Oman. 



The highest salinity (37.40%,) was found at 200 meters at station 3, and the 

 lowest salinity (34.74% ) was found at 3500 meters at station 47. 



Temperatures generally decreased from surface to bottom. The lowest temper- 

 atures (1 ,70°C .) were recorded at 3168 meters at station 39 and at 3500 meters at 

 station 47.
