    Hmmm.  How could these dips be known about almost 30 years ago before
    GPS?
    
    Also, can you give a better reference for this Maritime Center?  A
    search on Google does not show any IBM Maritime Centers - in Italy
    or anywhere else - and I doubt that IBM would even have a Maritime
    Center, unless they made a donation to something that caused their
    name to be prefixed to an existing organization.  Nevertheless, I
    cannot find any IBM Maritime Centers (or Centres) that are known
    publicly by that name.  (What would the Italian name be?)
