Chesapeake Lightship and Light Station (fig. 12, table 12) 



Surface water temperatures were near normal during most of 

 the year in spite of the prevailing subnormal air temperatures. An 

 exception to the general rule was the cold period of the first 2 

 decads of May when records were broken at both surface and bottom. 

 Air temperatures were above normal most of May. 



The salinity minimum, 28.08 °/oo for the last decad of May, 

 is the second lowest value in the period of record.
