A 26-year AVHRR Sea Surface Temperature dataset from 1992 to 2018 maps the East Australian Current off northern New South Wales. The Australian Ocean Data Network provides this data, which was processed using a Topographic Position Index technique. The analysis shows the current moves an average of ~6 km closer to the coast in austral summer and autumn, occupying a shelf area ~12% larger.
Use Cases
- Modeling seasonal coastal upwelling patterns based on the quantified shoreward intrusion of the East Australian Current.
- Analyzing long-term trends in shelf circulation dynamics based on the 26-year satellite SST record.
- Validating hydrodynamic models of the East Australian Current using direct measurements of distance-to-coast and occupied area.
Strengths
- 26 years of continuous satellite-derived Sea Surface Temperature data from 1992 to 2018.
- Provides direct, quantitative measurements of current intrusion (distance and area) previously subject to dispute.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
