Reference Level

The tide staff zero has been linked to fixed benchmarks by the contributors. The documentation shows the tide staff to be stable relative to the benchmarks throughout the period. However the data reveal numerous level shifts between 02 April - 31 December 1989. After investigation by the originators into the tide staff readings and original analog rolls, it has been determined that these shifts are not correctable.
