Georges shoal > Texas Tower §2 (Figure 5, Table 5) 



Ten day mean surface water temperatures ranged from a mini- 

 mum of ^.4 F in mid -February to a high of 6A.,2°F in mid-September. 



Comparison with the 1956 readings, which began in April of 

 that year, shows the mean for the same period in 1957 to be 2.7°F 

 higher. This year warming began abruptly during the last 10 days of 

 April, nearly a month earlier than in 1956. All the K) day mean values 

 for 1957 from the end of April through the first 10 days of December 

 were above the comparable values for 1956. Beginning in mid -November, 

 cooling was more rapid in 1957. 



It is regrettable that there were so few salinity samples 

 taken in 1957. IVhat values there are give means of greater than 

 33.0 °/oo.
