Tide gauge benchmarksBM 1: the top of a concrete block protruding about 0.3m above ground level and marked ZNI. It is surrounded by a rectangular concrete collar which shows latitude, longitude & height in feet above MSL.
Benchmark relationshipsTide Gauge Zero (TGZ) = 5.432m below BM 1 (1965 onwards)
Auxiliary benchmarksBMR 8290 3092 NMV/C/443: small piece of blue metal gravel embedded in and protruding slightly above the concrete top of the sea wall. NMV/C/444 & NMV/C/445: centres of triangles carved in flat concrete on the top of the sea wall of the jetty, with their numbers next to them. TRIG 'M': drill hole in a damaged concrete block.
