Tides were measured using a portable pressure transducer secured just below low water line. A 22 hour record was obtained. A connection was made to the local Pageos benchmark by leveling and a 2 hour GPS observation. Additionally, the National Tidal Centre also has tidal data from Heard Island for 1948, 1980 and from 1986-1987. Documentation dated 2001-03-07 Heard Island Tide Gauge. A Platypus Engineering tide gauge was deployed in a heavy steel tetrahedral mooring in Atlas Cove in 1993. Two attempts have been made to recover the gauge without success. In March 1997 a temporary tide gauge was used to obtain a 22 hour record. A rock bolt was placed in the rock close to the deployment site and a connection was made to the Pageos Site by a 2 hour GPS observation. A level and staff was used to measure the height of the temporary gauge relative to the BM (AUS258). From these observations an approximate MSL can be found.
