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

November 2016 to March 2017 daily composites of sea surface temperature derived from hourly Himawari-8 satellite imagery. The dataset maps the dynamics of the seasonal Bonney Coast Upwelling, a key ecological feature in Australian waters. The work was presented at the 2017 Australian Marine Sciences Association Conference.

Use Cases

• Analyze the daily spatial extent and intensity of the Bonney Coast Upwelling based on mapped upwelling signatures.
• Investigate the temporal development of an upwelling event from onset to termination based on daily composites.
• Study connectivity between the Bonney Coast Upwelling and other local features off Kangaroo Island and the Eyre Peninsula.
• Compare satellite-derived sea surface temperature data with other physical oceanographic techniques mentioned in the description.

Strengths

• Provides daily composites, overcoming cloud contamination limitations of twice-daily MODIS and AVHRR passes.
• Focuses on a specific, ecologically important region (Bonney Coast) during a defined season (Austral summer).
• Uses data from the Himawari-8 geostationary satellite, operational since late 2015.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data coverage is limited to a single season (November 2016 - March 2017).
