Relatively warm surface water temperatures in January gave way in late 

 February to a minimuin for the year of 35.0 F. This was 5 F belov; the mean. 

 Warming was rapid and advanced beyond the mean in late April and May. 

 Bathythermograph slides for the first half of June were lost in transit. 

 After June, bottom temperatures Xv^ere read at 85 feet, since this appeared the 

 most consistent depth. (The lightship here apparently yaws over uneven bottom.) 

 The summer depression in temperature throughout the water column appeared 

 again in mid-July, after which surface values again advanced beyond the mean. 

 The summer maximum of 75 F occurred early in August. The influence of the 

 hurricanes in late August and September is again apparent. Chilling was 

 rapid except during November. 



As at Five Fathom Bank, salinities in January were above previous records, 

 but by late April had dropped off sharply. They remained consistently below 

 the 1957 readings. During July, August and September they vjere similar to 

 the 1956 readings, but during the autumn they were lower.
