Tide gauge benchmarksBenchmark 4 (1949) is the primary benchmark (PBM) stamped 'NO 4 1949' set in the northwest side of a 6ft by 12ft concrete manhole in the centre of the road.
Benchmark relationshipsTGBM is 9.83ft above Tide Gauge Zero (Station Datum) NOAA Chart Datum (MLLW) is 1.24ft above Station Datum Mean Sea Level (1960-1978) is 2.65ft above Station Datum
Auxiliary benchmarks9 additional benchmarks are levelled to the TGBM and the Tide Station on a yearly basis. BM's L, 5, and USN BM1 subsided during earthquake - October 1993 site inspection was primarily for levelling due to recent earthquake. Other benchmarks include: BM 11, BM 4, BM 12, BM 13, BM 7 (P.I.E.), BM K, BM 6, BM 13
