This dataset is hourly data values (averaged from 6 minute values), per seaframe station, for sea level, barometric pressure, water temperature, air temperature, sea level Adjusted Residuals, sea level Residuals, wind speed, wind gust, and wind direction*.
(Only sea level data is available, from Lorne and Stony Point stations )
Data is from approximately 1992, from the following 16 tide gauge stations (14 operated by BOM) : Townsville - Cape Ferguson [QLD] (1991+), Rockhampton - Rosslyn Bay [QLD] (1992+), Port Kembla [NSW] (1991+), Stony Point [VIC] (1993+), Lorne [VIC] (1993+), Burnie [TAS] (1992+), Triabunna - Spring Bay [TAS] (1991+), Portland [VIC] (1991+), Adelaide - Port Stanvac [S.A] (1992 to 2010), Thevenard [S.A.] (1992+), Esperance [W.A.] (1992+), Perth - Hillarys [W.A.] (1992+), Broome [W.A.] (1991+), Darwin [N.T] (1991+), Milner Bay - Groote Eylandt [N.T] (1993+), Cocos (Keeling) Islands (Indian Ocean) (1993+)
A summary of each station's position (lat, long, SSBM, AHD) is available from http://www.bom.gov.au/oceanography/projects/abslmp/data/data.shtml
More station detail (including Australian Height Datum in metres above that station's Tide Gauge Zero, latitude, longitude, monitoring equipment, the station's BOM Station#, ANTT#, GLOSS ID, etc), are available by clicking the port name, on the webpage, or by using this URL formula:

(the ANTT# is provided in the Keywords section of this metadata record)
Dates and times, in the data, are given in Universal Time Coordinated (UTC).
Sea level values are in metres above Tide Gauge Zero (e.g. 1.205 metres)
(The Australian Height Datum in metres above tide gauge zero is provided in the station details PDF document.To convert the data to be relative to AHD, subtract that station's AHD value from the observed sea level value.)
Missing or erroneous values are set to a value of -9999
14 of the 16 stations are SEAFRAME stations which measure sea level very accurately, and also record meteorological parameters (such as air and water temperature, pressure and wind observations).
