The temperature and salinity distribution fomid along the extra- 

 southerly sections of the fii'st survey are shown in figures 32-35. 

 Departures of the individual stations from the specified meridian may 

 be seen l)y referring to figure 24. The various bands of current shown 

 in the dynamic topographic chart can also be identified in the tem- 

 perature and salinit}- sections. Comparing the two sections it will 

 be seen that the highest temperature in the western section is slightly 

 warmer than in the eastern section. Otherwise the temperatures and 

 salinities within particular current bands show little difference between 

 the two sections. 



The section along the meridian of 50°15' W.. has been occupied by 

 ships of the International Ice Patrol before. In 193S. the General 

 Greene occupied the section during the period when the Armour 

 Hansen and Altair were engaged in their investigation of the Gidf 

 Stream system in the Azores sector. The Ererf/reen occupied the 

 section in 1950 at the time of Operation Cabot and again in 1958 as a 

 part of the activity of the International Geophysical Year.
