172 Salinity of the Ocean, its Variation in Oceanic Space and in Time 



Indian Oceans, we know their formation and spreading are still very pure. The much 

 stronger intensity of this phenomenon in the Pacific Ocean has been shown by several 

 recent oceanographic stations but detailed information about their extent is still 

 lacking. 



(c) 772^ Salinity of the Stratosphere 



The vertical salinity distribution in the stratosphere of the three oceans can best be 

 discussed by means of longitudinal sections through the Atlantic, the Indian Ocean 

 and the Pacific. The longitudinal section through the Atlantic Ocean is that given by 

 WusT (1936) through the Western Trough from the Weddell Sea to Davis Strait (see 

 Fig, 62). In the Indian Ocean a central section (Fig. 75) from the Antarctic to the south- 

 ern tip of India has been selected (Moller, 1929); the Pacific Ocean is characterized 

 by a vertical section through its eastern half (Fig. 76). In the northern part this section
