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. Some further information about the data can be found in the download file.
