Reference Level

All heights have been referred to the station tide staff zero which is linked to fixed bench marks

Benchmarks

Benchmark Description
The NOS Benchmark disk, stamped '1 1989', is set into the concrete sea wall of the dock at Kings Wharf, near the Ports Authority Office Building.
2 1989 Screw 6 unstamped. (Mark destroyed 1992)
3 1989 Screw 7 unstamped. (Mark dropped 1993)
4 1989 Screw 8 unstamped. (Mark dropped 1993)
1-TG Unstamped. The brass screw is inset in a triangle two feet south of the tide house and 1.5 feet from the edge of the wharf.

Quality Assessment by the UH Sea Level Centre

Comment

The 1972-10/28/1975 data are from the Coastal Geodetic Survey and were keypunched at Scripps(D.Luther).The residuals and comparisons with Noumea warranted the adjustment of -5cm from 12Z 11/21/72 - 03Z 04/05/73. Based on an overlap of November-December 1975 with the exisiting series,the CGS series was adjusted by adding 162mm. This span has poor timing and many short gaps.

The site was moved in March 1989 to Latitude: 18° 08.2' S, Longitude: 178° 25.6'E and is maintained by NOS. Based on an overlap of March-May 1989, a constant was determined for relating the NOS data to the historic tide staff zero. A constant of (-10347 mm) was added to the data as provided by NOS. The data from the L&S ADR gauge begin on 01 June, 1989. A common bench mark is also available between the two time periods for comparisons of geodetic surveys. However, the segment from 1989 to early March 1994 appears high by about 7 cm. This feature is under investigation by NOS.
