Sea level data
National Tidal Centre (NTC) - Australia
The National Tidal Centre (formerly the National Tidal Facility) is reponsible for sea level monitoring and analysis for the purpose of deriving trends in absolute sea level and producing national tide predictions, tide streams and related information.
The NTC is the primary source of tide tables, tidal streams and tidal constituents provided to the Australian Hydrographic Service. The NTC also manages the national data archive for sea levels and tides.
They hold the great majority of Australian historical tide gauge data and also maintain, and
process and archive data from, two modern arrays of high quality acoustic tide gauges - the
Australian Baseline array (ABSLMP) and the Pacific array (SPSLCMP).
