Brief description

Hourly and 15-minute ocean water levels from New South Wales (NSW) coast were provided by Manly Hydraulics Laboratory (MHL) and Australian Bureau of Meteorology (BOM) data for this region. The organisations collect coastal water levels from different ocean tide gauge types that include: onshore bay, onshore river entrance, and offshore open ocean. However, the onshore river entrance gauges are susceptible to large peaks due to rainfall and the offshore open ocean gauges lack a persistent datum. Therefore, the datasets were adjusted to the vertical Australian Height Datum (AHD) and had the rainfall-related peaks removed from the records. Tidal anomalies, which represent the difference between observed water levels and the predicted tide were obtained through the Unified Tidal Analysis and Prediction model (Utide). The aim of the study is to compile a high-quality set of residuals consistent in datum. This data collection accompanies a data descriptor paper in the 'Data' Journal, it has been assigned a DOI and will be maintained in perpetuity by the Australian Ocean Data Network (AODN).

Statement: Nine water levels were provided in kind from different institutions: six from Manly Hydraulic Laboratory (MHL) and three from the Bureau of Meteorology (BoM). the water levels were recorded using different types of ocean tide gauges, including Onshore River Entrance, Offshore Open Ocean and Open Bay or Harbour. Five water level records were recorded every 15-minutes, and the remaining four every one hour. These records were used to obtain residuals, which are the difference between observed water levels and predicted tides. For that matter, Utide predictor was used to reconstruct the predicted tides which were then subtracted from the observed water levels to obtain the residuals.
