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. {"type": "Polygon", "coordinates": [[[147.05, -41.5], [147.25, -41.5], [147.25, -41.300000000000004], [147.05, -41.300000000000004], [147.05, -41.5]]]} 147.05 147.25 -41.5 -41.300000000000004 HOBO U20L-04 Water level Data Logger DATA ACCESS 1 - raw supplied data pre-July 2016 (flood) (.xlsx worksheets) documentDigital ZIP DATA ACCESS 2 - from Dec 2016-Feb 2018 (.csv) documentDigital CSV SUPPLEMENTARY INFO - additional logger metadata (.pdf) documentDigital PDF imas:Tamar_tidal_height documentDigital MAP - location of loggers WMS RELATED DATA - Tamar sea level data March-August 2018 documentDigital HTML View and download this data through the interactive IMAS Data Portal. documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
