                             This reference zero is unique to this station and
                             is not an official datum (chart, national, etc.) 
                             and is not relative to local tidal parameters, 
                             such as mean lower low water.  See the Originators

              Comment      : The daily and monthly means reveal no apparent     
                             changes in the reference level.  The station has
