Southern Ocean Phytoplankton and Carbon Flux Research in Amundsen and Ross Seas

A 2009 research project from AMD_USAPDC on NASA EarthData examines phytoplankton dynamics and carbon export in the Southern Ocean. The study compares the well-studied Ross Sea and the poorly described Amundsen Sea to understand biological responses to physical and chemical controls. Broader impacts included international graduate participation, public outreach, and collaboration with educators.

Use Cases

• Modeling phytoplankton assemblage changes based on temperature, light, iron, and CO2 levels described in the study
• Comparing carbon export efficiency between two distinct Antarctic continental margin regions
• Analyzing mechanisms of the biological pump based on phytoplankton biomass and composition
• Investigating how physical forcing leads to distinct chemical and biological conditions in polar seas

Strengths

• Focuses on a direct comparison between a well-studied and a poorly described region, which may provide unique mechanistic insights
• Research design addresses multiple specific factors: temperature, light, iron supply, and carbon dioxide levels
• Project included broader impact activities like outreach and educator collaboration, suggesting potential for ancillary educational data
