Winter Quarter Lightship (Figure 14, Table 14) 



After two months of near normal temperatures in January and 

 February, surface temperatures rose rapidly and remained well above the 

 mean throughout the year. This trend more nearly parallels air tempera- 

 ture anomalies than do the records at Five Fathom Bank to the north and 

 Chesapeake to the south. The highest surface temperatures occurred 

 in the first decade of September; the mean for that month was the highest 

 on record. 



The three distinct intrusions of cold water at the bottom in July, 

 August and September were also observed at Five Fathom Bank and 

 Chesapeake stations. The maximum bottom temperature appeared on 

 September 19th after force 6 northeasterly winds mixed the water column. 

 In terms of 10-day means the bottom maximum of 56°F equals the maximum 

 of 1957. 



Surface salinity during the year was slightly above those for 19 56 

 and 1958 but well below those for 1957,
