                             staff zero which is linked to fixed bench marks.
                             This series is independent from 249B and 249C
                             because confirmation of linkage to a common datum
                             has not been made.
                             These data were digitized at the University of
                             Hawaii Sea Level Center.  Tide staff readings
                             were provided; however, it appears the corrections
                             to a fixed datum were already applied to the
                             tabulated heights.  
              Comment      : The timing is appears to be good throughout.
