With reference to the history of the ratio of sea level changes to atmos- 

 pheric changes varying from a value of 1, Ted Saur reported on this in AGU 

 several years ago and the Coast and Geodetic Survey published on this over 100 

 years ago, using a four-year record of tide and pressure at Boston. 



In considering additional forces related to the problem, I note that you set 

 the wind stress on the surface as equal to zero. I suggest that although it is an 

 order of magnitude less than the term due to atmospheric pressure fluctuation 

 and thus not large enough to account for the variations noted, it still can be a 

 significant disturbing parameter.
