Sea Surface Temperature Anomalies for Coral Bleaching Risk on Great Barrier Reef

Aggregating Sea Surface Temperature anomalies (SSTa) derived from satellite observations, used to assess coral bleaching risk for the Great Barrier Reef. It provides high-resolution nowcasts based on a 1-day L3S night-only SST product from the Integrated Marine Observing System (IMOS). The system became operational in October 2013, comparing current SST to long-term climatologies from 1993-2003 or 2002-2011.

Use Cases

• Analyze Sea Surface Temperature anomalies (SSTa) to correlate magnitude and duration of warm events with historical coral bleaching patterns.
• Use the 1-day L3S night-only Sea Surface Temperature (SST) product for high-resolution nowcasting of thermal stress over the Great Barrier Reef.
• Identify grid cells with missing SST data due to cloud cover to assess spatial data completeness for environmental monitoring.
• Compare current SST values against the CSIRO Legacy climatology (1993-2003) or IMOS climatology (2002-2011) to calculate long-term temperature deviations.

Strengths

• Provides high-resolution satellite-based nowcasts of Sea Surface Temperature and thermal stress.
• Data supports correlation analysis between SST anomalies and past coral bleaching events.
• Operational system has been in place since October 2013, providing a multi-year time series.
• Product is focused on the Great Barrier Reef region, a critical marine ecosystem.

Limitations

• SST data cannot be calculated in grid cells affected by cloud cover, leading to spatial gaps.
• The specific data volume (rows, size) and columnar structure are not provided, limiting understanding of dataset scale.
• Primary file formats (HTML, PNG, PDF) suggest the data may be presented as reports or images rather than a structured, machine-readable table.
