Gap-filled, gridded subsurface physical oceanography time series dataset derived from selected mooring measurements off the Western Australia coast during 2009-2023

This collection presents a gap-filled, gridded time series dataset of daily ocean temperature and current, collected from an array of 6 coastal Integrated Marine Observing System (IMOS) moorings off the southwest coast of Western Australia (WA) during 2009-2023, at depths ranging from 47 m to 500 m. Self-Organizing Map (SOM) is used to fill the data gaps.

The collection also provides a daily gridded mooring dataset of temperature, salinity, and current without gap-filling. Monthly average data are also included. Monthly data were then derived from daily data if there were more than 10 days of data during that month.

This integrated dataset provides an overview of data availability and allows users to have quick access to the mooring data, without the need of manipulating over one thousand files individually. This unique dataset offers an invaluable baseline perspective on water column properties and temporal variability in WA coastal waters. The data can be used to characterise subsurface features of extreme events such as marine heatwaves, marine cold-spells, and to detect long-term change signals along the WA coast, influenced by the Leeuwin Current and the wind-driven Capes Current.
