Please note: In many cases, the station position in our database is accurate
to only one minute. Thus, the tide gauge may not appear to be on the coast.

Using information from the NOAA website the RLR diagram has been revised. Previous Primary benchmark BM 8 - named 8 1924 on the NOAA site appears in the 1984 report with a value of 5.518m relative to gauge datum but does not appear in the 2003 report. Current Primary benchmark is 1600 L 1982 with a value of 13.669m above gauge datum.
