Trans. : Yes Distribution : 1975-2018 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 levelling history. Data from Papeete-A are maintained in a separate record because these two series are not linked to the same tide staff zero. The NOS gauge replaces the UH gauge as of July 1992. A two-month overlap (May-June 1992) provided the link (-11687 mm) to refer the NOS data to the historic reference level. The primary bench mark is NU3. Comment : The daily and monthly means reveal no apparent changes in the reference level. The JASL update of 09 Apr 2019 replaces 01 Jan 2016 - 05 Sep 2017.
