Pressure loggers deployed in the water recorded total pressure and the inverse barometer effect was accounted for by two additional pressure loggers deployed above ground within 15km of a station. The data include barometric pressure, water temperature, and water level relative to Australian Height Datum (AHD83). The data captures tidal amplification and asymmetry between ebb and flood tides in the estuary for the purpose of a research project completed in 2018 by Karen Palmer. Based on the Tamar estuary model created for NRM North by BMT WBM Pty Ltd using TUFLOW FV (with permission), a new hydrodynamic model was created and calibrated with observed water levels. Different scenarios of sea level rise and bathymetry change were then simulated to model the effects on tidal amplitude and phase. {"type": "Polygon", "coordinates": [[[146.789886412, -41.4601706919], [147.204620257, -41.4601706919], [147.204620257, -41.1386902547], [146.789886412, -41.1386902547], [146.789886412, -41.4601706919]]]} 146.789886412 147.204620257 -41.4601706919 -41.1386902547 DATA ACCESS - All stations (zipped .csv) documentDigital ZIP SUPPLEMENTARY INFO - additional logger info (all stations combined, zipped .pdf) documentDigital ZIP REPORT - Seaport tide gauge calibration report [direct download] documentDigital PDF RELATED DATA - Upper Tamar Tidal Height Data (Seaport tide station WL5 2014-2017) documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
