?fi.nimuTn surface temperature of 3^°? occurred during the last 

 third of January. Surface temperatures remained less than hO until 

 durinr; the first third of April. The vernal warming la-;ged behind the 

 mean for the per-^ od of record 19U7-19'?6 until the end of June. Maxn.mum 

 temperatures of T^F were observed during the first third of September 

 followed by autvimnal cooling virtually identical with the mean for the 

 period of record. 



The thermocline commenced development in April, reached its 

 maximum in July. Maximum temperature at the bottom of nearly 611°^ was 

 reached in early October when the autumn overturn reached the bottom fol- 

 lowing vriiich the temperatiire in the water column was essentially isother- 

 mal for the remainder of the year . 



The surface salinity commenced at the beginning of the year at 

 sUghtly above 32°/00, gradually descended to a minimum of just over 

 30°/00 during mid-J;me and gradually recovered tc just imder 32°/00 by 

 year end. Bottom salinities remained, for the most part, in the vicinity 

 of 32°/00. Surface and bottom salinities took an unexplained jump in the 

 last third of October to 33°/00.
