Bonney Coast Upwelling Daily Sea Surface Temperature Composites from Himawari-8, 2016-2017

November 2016 to March 2017 daily sea surface temperature composites derived from hourly Himawari-8 satellite imagery, focusing on the Bonney Coast region of Australia. The dataset was generated by Geoscience Australia to map upwelling signatures using a topographical position index method. It was presented at the 2017 Australian Marine Sciences Association Conference.

Use Cases

• Tracking the daily spatial and temporal development of the Bonney Coast Upwelling from onset to termination.
• Investigating connectivity between the Bonney Coast Upwelling and other local upwelling features off Kangaroo Island and the Eyre Peninsula.
• Analyzing sea surface temperature patterns to mitigate cloud contamination issues present in lower-frequency satellite data.

Strengths

• Uses high-temporal-resolution hourly Himawari-8 satellite data to overcome cloud contamination limitations of previous sensors.
• Provides daily composites for a full upwelling season (November 2016 - March 2017), enabling detailed temporal analysis.
• Applies a specific topographical position index method to isolate upwelling signatures from the imagery.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data freshness should be verified; the record was last updated on 2026-04-20.
