[TS]-relationship and Connection with Mixing Processes and Large Water Masses 213 



dional increase in salinity is less, reaching 34-5%o at the equator, and from there to 

 20° N. the increase is again more rapid (up to 34-9%o). According to the distribution 

 of the isohalines, stronger mixing occurs at the western edge of the ocean. [TS\- 

 relations of the core layer for the western and eastern parts of the ocean are approxi- 

 mately the same for the two halves of the ocean so that a standard curve can be pre- 

 pared for the entire area where this water type (Fig. 101) is found. The point Zp 

 represents the mean properties of the unadulterated water in the area of formation 

 near the oceanic Polar front and the last traces of this water type are found at point 

 O. Dividing the interval between Zp and O into 100 parts allows the determination of
