Daily Sea Surface Temperature Composites for Bonney Coast Upwelling

Daily sea surface temperature composites derived from hourly Himawari-8 satellite imagery for the Austral summer of 2016-2017. This study maps the Bonney Coast Upwelling using a topographical position index method to analyze its spatial and temporal development. The data was presented at the 2017 Australian Marine Sciences Association Conference.

Use Cases

• Analyze daily sea surface temperature patterns to track the onset and termination of the Bonney Coast Upwelling.
• Investigate connectivity between the mapped Bonney Coast Upwelling and other local features off Kangaroo Island and the Eyre Peninsula.
• Use the topographical position index method to isolate upwelling signatures from daily satellite composites.
• Study the temporal frequency of upwelling events on a scale of days to weeks during the Austral summer season.

Strengths

• Data overcomes cloud contamination limitations of previous sensors by using hourly Himawari-8 imagery.
• Provides daily composites for a full upwelling season from November 2016 to March 2017.
• Enables first quantitative investigation of the Bonney Coast Upwelling's spatial and temporal development.

Limitations

• Data is limited to a single upwelling season (2016-2017), restricting long-term trend analysis.
• Primary data format is PDF, which may require extraction and conversion for computational analysis.
• Methodology relies on a specific topographical position index technique for signature isolation.
