14 years of monthly MODIS satellite data map the spatial and temporal variability of coastal upwelling along 4500 km of Australia's southeastern coast. The dataset identifies two persistent upwelling systems, one in New South Wales and another in western Victoria/South Australia, with varying intensity and drivers. Zhi Huang and Xiao Hua Wang published this analysis in Remote Sensing of Environment in 2019.
Use Cases
- Modeling the impact of El Niño/La Niña events on upwelling intensity based on described ENSO correlations.
- Analyzing seasonal variability in chlorophyll-a concentrations for ecosystem productivity studies.
- Mapping the spatial extent and influence area of wind-driven versus current-driven upwelling systems.
- Studying inter-annual variability in Sea Surface Temperature (SST) anomalies along the coast.
- Correlating upwelling speed and intensity with regional fish catch data for economic analysis.
Strengths
- Data spans 14 years, providing a long-term temporal record for analysis.
- Coverage extends along a 4500 km coastline, offering significant spatial scope.
- The study distinguishes between two major upwelling systems with different drivers and seasonal patterns.
- Analysis includes multiple variables: SST anomaly, chlorophyll-a concentrations, area of influence, and upwelling speed.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
