Trans. : No Distribution : 1986-2018 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. The station tide staff zero is 4.188m under P.485. Comment : The data quality and timing accuracy were lower while the ADR was the gauge, prior to 2008. A large number of days had short gaps that were interpolated 2008-2017. The JASL update of 12 Apr 2019 replaces 01 Jan 2016 - 05 Sep 2017.
