Data from this Fort Denison record were obtained from authority 93 up
until 1993. Data are MTL (high and low waters). Values for 1914 and
earlier are taken from a recomputation of the data by B.V.Hamon,
'A century of tide records: Sydney (Fort Denison) 1886-1986',
Flinders Institute for Atmospheric and Marine Sciences Technical
Report No.7, July 1987.
Later data from Fort Denison can be found in other PSMSL records and
are MSL, based on data from a new tide gauge.
