Tide Gauge Records, Heard IslandEntry ID: Heard_Tides
Abstract: 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.

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.

Quality The dataset between the time of deployment and recovery is complete. A chart showing what data are available is at the URL given above (Chart of available data). The dataset is complete except for a few days of records in late 1996. The portable gauge was deployed for 22 hours and when recovered the data were downloaded and processed. Tidal records are checked for gross errors in height values and obvious timing errors.
Access Constraints Records are stored in the form in which they are retrieved from the tide gauges and as converted data in the form of water heights above the tide gauge transducer. Raw data and processed data are available on request from the National Tidal Centre.
