Data from 2 sites prior to 1959 MSL values based on readings of high and low waters.Data prior to 1962 referred to BM which has proved unstable irregularities in records for 1940 & 1941. 1940-41. Data therefore ommitted gauge at new site in September 1965.

Documentation added 1991-06-11

Lagos 210/031 RLR(1974) is 10.0m below BMOP

Documentation added 1992-08-06

The 1941 irreularities may be connected with the 1941 earthquake - See Bottari et al. , tecttonophysics 202, 269-275, 1992 and Yamguti, R.Soc.New Zealand bulletin , 9, 127-128, 1971.
