Ten day mean surface water temperatures ranged from a mini- 
mum of 40.4°F in mid-February to a high of 64.2°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°R 
higher, This year warming began abruptly during the last 10 days of 
April, nearly a month earlier than in 1956. ll the 10 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. What values there are give means of greater than
