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. Primary benchmark is now 5371 A 1977 with a value of 2.6m relative to the gauge datum in the NOAA report of 2003 and 2.597m in the report of 1989. Previous benchmark NO 13 1962 is mentioned in the 1989 report with the same value of 4.386m relative to the gauge datum but does not appear in the 2003 report.
