              Refernce Levl: Heights are referred to the station tide staff 
                             zero, which is linked to land-based benchmarks. 
                             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
                             for benchmark descriptions, maps, and the geodetic

              Comment      : The daily and monthly means reveal no apparent     
                             changes in the reference level and agree with      
                             Christmas.  The timing is poor from late April to  
                             Oct. 1990 due to sand intruding the stilling well.
