Abstract
Continuous water level records are required to detect long-term trends and analyse the climatological mechanisms responsible for extreme events. This paper compiles nine ocean water level records from gauges located along the New South Wales (NSW) coast of Australia. These gauges represent the longest and most complete records of hourly—and in five cases 15-min—water level data for this region. The datasets were adjusted to the vertical Australian Height Datum (AHD) and had the rainfall-related peaks removed from the records. The Unified Tidal Analysis and Prediction (Utide) model was subsequently used to predict tides for datasets with at least 25 years of records to obtain the associated tidal residuals. Finally, we provide a series of examples of how this dataset can be used to analyse trends in tidal anomalies as well as extreme events and their causal processes.

The frequent recording of ocean water levels facilitates the effective management of coasts and estuaries, providing data for the investigation of coastal and estuary dynamics, oceanographic and climate research, and long-term sea-level monitoring [1,2,3]
The difference between the predicted astronomic and measured water levels is known as a tidal residual, which represents the non-astronomical effects on the water level [10]
Summary
The frequent recording of ocean water levels facilitates the effective management of coasts and estuaries, providing data for the investigation of coastal and estuary dynamics, oceanographic and climate research, and long-term sea-level monitoring [1,2,3]. Flood removal approaches vary, affecting the magnitude of tidal residuals generated in ORE gauges Given these limitations, not all ocean water level datasets can be used to obtain reliable tidal residuals. This paper describes how data from different ocean tide gauges on the NSW coast were processed to generate a set of high-quality, long-term tidal residuals consistent in datum. It details the process followed to obtain tidal residuals from the observed water levels
