Upwelling Frequency Along Australia's South-Eastern Coast

Upwelling Frequency Data of the South-eastern Coast of Australia is a GIS data layer showing the frequency of coastal upwelling events. The dataset was generated using 14 years of monthly MODIS sea surface temperature data, with higher values indicating persistent or semi-persistent upwelling and medium values indicating seasonal upwelling. It is hosted by the Australian Ocean Data Network and is detailed in a 2019 publication in Remote Sensing of Environment.

Use Cases

• Identifying persistent upwelling zones for marine protected area planning based on upwelling frequency.
• Analyzing seasonal versus year-round upwelling patterns using the classified frequency values.
• Correlating upwelling hotspots with biological productivity data for ecological studies.
• Validating regional oceanographic models with a 14-year observational upwelling record.

Strengths

• Based on a long-term observational record of 14 years of MODIS satellite data.
• Spatially distinguishes between persistent, semi-persistent, and seasonal upwelling regimes.
• Methodology is peer-reviewed and published in a scientific journal.

Limitations

• Key metadata such as specific column names, row count, file size, and license are not provided on the platform.
• The dataset's temporal coverage is not explicitly stated beyond the 14-year processing period.
• Data format is listed only as ZIP, lacking detail on the internal GIS data structure.
