The Australian Ocean Data Network provides a dataset mapping the East Australian Current (EAC) off northern New South Wales between 28°S and 32.5°S. It uses a 26-year remotely sensed AVHRR Sea Surface Temperature dataset from 1992 to 2018, processed with a Topographic Position Index technique to quantify shoreward intrusion. The analysis provides direct measurements of intrusion area and distance.
Use Cases
- Analyzing seasonal migration patterns of the East Australian Current based on distance-to-coast measurements
- Modeling coastal upwelling and shelf circulations based on the quantified shoreward intrusion data
- Studying the impact of ocean current seasonality on coastal marine ecosystems based on the described bio-physical dynamics
Strengths
- 26-year temporal coverage from 1992 to 2018
- Direct measurement of intrusion metrics (area and distance)
- Quantitative mapping using a Topographic Position Index technique
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
