Mean hydrography on the continental shelf from 26 repeat glider deployments along Southeas

26 glider missions between 2008 and 2015 collected over 33,600 CTD casts on the continental shelf of southeastern Australia. This dataset provides gridded mean fields for temperature, salinity, density, dissolved oxygen, and chlorophyll-a fluorescence. The data is presented by the Australian Ocean Data Network, offering high-resolution observations of shelf waters adjacent to the East Australian Current.

Use Cases

• Modeling shelf water properties based on gridded temperature and salinity fields.
• Analyzing phytoplankton biomass dynamics based on chlorophyll-a fluorescence data.
• Studying the separation zone of the East Australian Current based on high-resolution spatial observations.
• Investigating cross-shelf gradients in dissolved oxygen based on data gridded along isobaths.

Strengths

• Over 33,600 CTD casts provide a substantial observational record.
• Data spans 7 years (2008-2015) from 26 separate glider deployments.
• High-resolution spatial coverage from the surface to within 5 meters of the seabed.
• Includes five measured variables: temperature, salinity, density, dissolved oxygen, and chlorophyll-a fluorescence.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
