A 26-year remotely sensed dataset maps the seasonal shoreward intrusion of the East Australian Current (EAC) off northern New South Wales. The Australian Ocean Data Network produced this dataset using AVHRR Sea Surface Temperature (SST) imagery from 1992 to 2018. It enables direct measurement of intrusion area and distance-to-coast.
Use Cases
- Analyzing seasonal migration patterns of ocean currents based on distance-to-coast measurements
- Investigating coastal upwelling and shelf circulation drivers based on intrusion area data
- Modeling bio-physical dynamics on the slope-shelf based on long-term SST observations
- Studying the influence of high-frequency eddy-current systems on low-frequency coastal variability
Strengths
- 26-year temporal coverage from 1992 to 2018 provides a long-term observational baseline
- Direct quantitative measurements of intrusion area and distance-to-coast are enabled
- Analysis reveals specific seasonal patterns, with mean distance ~6 km shorter and shelf area occupancy ~12% larger in summer/autumn
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 bias inherent to the specific study region between 28°S - 32.5°S
