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.

BM1 was an old mark that no longer exists. Benchmark 5535 H 1978 2.445m above station datum was the Primary benchmark for the Bermuda Biological Station gauge. Benchmark 5540 A 1979 is the Primary benchmark for the Esso Pier tide gauge. From the NOAA website is the following warning 'Benchmarks 5535 F 1978 and 5535 H 1978 are based on one differential levelling connection and do not meet the quality control standards of NOS. Therefore, caution should be used when deriving elevations for these marks'.
