Upper Tamar Tidal Height Data

Two OneTemp HOBO pressure data loggers were installed at the Seaport Marina in central Launceston in June 2014 by Dr Ian Kidd, measuring water depth at 1-hr intervals as well as water temperature. Depth is calculated from temperature, total pressure, and barometric pressure, based on fresh water density. The height of the gauge relative to AHD was measured 23 March 2018 by Launceston City Council surveyor Leigh Cornwell, and a correction applied to the data to give water level in metres AHD. The gauge was installed for the purpose of Dr Kidd's PhD research into sediment transport processes in the upper Tamar, and remains open with data collected monthly by Karen Palmer (IMAS honours student). Both projects were supervised by Dr Andrew Fischer.
