in depth between 1411 and 1847 meters. The 

 one deep cast of 4527 meters was taken in 

 water that was 4755 meters deep. The distri- 

 bution of these stations about ECHO is shown 

 in Figure 4. The data are listed by NODC as 

 Ref. No. 31-855 ML and as Table II of this 

 report. 



Eleven oceanographic stations were taken by 

 the USCGC ANDROSCOGGIN (WHEC 68) 

 during the period 1-20 June 1967. Two stations 

 had useful data to depths of 532 and 581 

 meters. One deep cast was made to a depth of 

 2846 meters, and the remaining eight stations 

 ranged between 1182 and 1601 meters. The dis- 

 tribution of these stations about ECHO is 

 shown in Figure 5. The data are listed by 

 NODC as Ref. No. 31-1087 AI and ase Table 

 III of this report. 



The USCGC ABSECON (WHEC 374) took 



20 oceanographic stations during the period 17 

 July-6 August 1967. Samples from nineteen of 

 these stations ranged in depth between 1305 

 and 1590 meters. The deep cast taken on this 

 patrol was to a depth of 4445 meters. The dis- 

 tribution of these stations about ECHO is 

 shown in Figure 6. The data are listed by 

 NODC as Ref. No. 31-1140 AZ and as Table 

 IV of this report. 



Seventeen oceanographic stations were taken 

 by the USCGC MCCULLOCH when she again 

 occupied ocean station ECHO from 27 Sep- 

 tember to 13 October 1967. Sixteen casts ranged 

 in depth between 1310 and 1785 meters while 

 one deep cast to 4030 meters was taken in 

 water 4206 meters deep. The distribution of 

 these stations about ECHO is shown in Figure 

 7. The data are listed by NODC as Ref. No. 

 31-1164 ML and as Table V of this report.
