Bonney Coast Upwelling Spatial and Temporal Variability from MODIS, 2002-2016

More than 170 satellite images map a key seasonal upwelling system along Australia's southern coast from 2002 to 2016. This dataset uses MODIS-derived Sea Surface Temperature and Chlorophyll-a data at approximately 1km resolution to analyze the system's dynamics. The research was presented at the 2017 Australian Marine Science Association Conference and aggregated by the Australian Ocean Data Network.

Use Cases

• Mapping the spatial extent of seasonal upwelling based on Topographic Position Index and image segmentation techniques.
• Analyzing inter-annual variability in upwelling intensity and timing based on the multi-year time series.
• Investigating correlations between upwelling events and marine life aggregations (e.g., krill, blue whales) based on described ecological features.
• Studying Sea Surface Temperature and Chlorophyll-a signatures within identified upwelling areas.

Strengths

• Contains more than 170 satellite images providing a 14.5-year time series from July 2002 to December 2016.
• Spatial resolution of approximately 1km allows for detailed coastal analysis.
• Quantifies upwelling impact, noting intensive events can influence over 10,000 km² with SST anomalies >1°C lower than surroundings.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is available only in PDF and HTML formats, which may limit direct machine-readability.
• Row count and specific data structure are unknown, which may limit suitability assessment.
