Summary about Tide Gauges Instruments from the Reports to SCAR prepared by K. Shibuya (NIPR, Japan) for the AGS'01 Symposium --------------------------------------------- AUSTRALIA Macquarie Island Foxboro pressure recorder, 22 March - 13 June 1964 Tide gauge, January 1967 - March 1971, continuing ? Mawson, Davis, Casey Absolute pressure, i.e. the pressure exerted by the water column and atmospheric pressure. Atmospheric pressure data corrected to sea level, is supplied by the Bureau of Meteorology, and is subtracted from the tide gauge data and correction is made for sea water to give a height of the water column above the tide gauge.
