Modeled Productivity Data for Three Major Antarctic Polynyas

46 Antarctic coastal polynyas are known, with this project focusing on three that account for over 50% of total polynya productivity. Ecosystem models for the Ross Sea, Amundsen, and Pine Island polynyas were developed by researchers from Stanford University and Old Dominion University to assess physical, chemical, and biological controls. The project aimed to understand present-day productivity and potential future changes under different climatic settings.

Use Cases

• Model phytoplankton abundance and productivity using coupled physical-biological model outputs for three polynyas.
• Compare differences in size and productivity metrics between the Ross Sea, Amundsen, and Pine Island polynyas.
• Assess the influence of meltwater runoff from Thwaites and Pine Island glaciers on polynya ecosystem processes.
• Project future changes in polynya function under different physical, chemical, and climatic scenario data.

Strengths

• Focuses on three major polynyas representing >50% of total Antarctic polynya productivity.
• Models are described as high-resolution and coupled, integrating physical and biological processes.

Limitations

• Specific row count, column details, and temporal coverage of the underlying model data are unknown.
• The dataset scope is limited to three specific polynyas, not all 46 known Antarctic coastal polynyas.
