The influence of other than purely local winds is apparent 

 as a better correlation between water moveinents and wind is obtained 

 from observing the position of fronts on the sequence of daily weather 

 maps than from the purely local observations on the lightship. Ihis 

 intrusion of offshore water is apparent at Winter Quarter and Five 

 Fathom Bank Lightships to a lesser degree, but at the same times as 

 at Chesapeake Lightship, indicating that this intrusion and regression 

 occurred all along this stretch of the coast.
