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

Daily sea surface temperature composites for the Austral summer of November 2016 to March 2017, derived from hourly Himawari-8 satellite images. This dataset maps the Bonney Coast Upwelling, a key seasonal ecological feature, using a topographical position index method. The work was presented at the 2017 Australian Marine Sciences Association Conference and aggregated by the Australian Ocean Data Network.

Use Cases

• Analyze the daily spatial and temporal development of the Bonney Coast Upwelling based on mapped sea surface temperature signatures.
• Investigate connectivity between the Bonney Coast Upwelling and other local upwelling features off Kangaroo Island and the Eyre Peninsula.
• Study seasonal wind-driven oceanographic features and their impact on fisheries and blue whale feeding grounds.

Strengths

• Uses hourly Himawari-8 satellite imagery, providing higher temporal resolution than previous MODIS and AVHRR passes (twice a day).
• Covers a specific upwelling season from November 2016 to March 2017, enabling analysis of the full seasonal cycle.
• Applies a topographical position index method to isolate upwelling signatures from daily sea surface temperature composites.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified as the last metadata update is dated 2026-06-27.
