SGER: Antarctic Phytoplankton Experiments on Iron and Vitamin B12 Co-Limitation

A Small Grants for Exploratory Research (SGER) project from 2008 conducted experimental incubations aboard the icebreaker Oden in the Amundsen and Ross Seas. The research investigated the effects of altered pCO2, pH, iron, and vitamin B12 on Antarctic phytoplankton communities, carbon cycling, and nutrient biogeochemistry. The work was organized by AMD_USAPDC and aimed to build international collaborations with the Swedish marine science community.

Use Cases

• Modeling phytoplankton community shifts based on experimental variations in iron and carbon dioxide.
• Studying nutrient co-limitation dynamics based on vitamin B12 and iron enrichment experiments.
• Comparing algal ecosystem responses between the Amundsen and Ross Seas as described in the research objectives.
• Analyzing carbon and nutrient cycling processes under simulated future climate conditions.

Strengths

• Focuses on a unique, opportunistic research platform in the little-studied Amundsen Sea.
• Experimental design includes manipulation of multiple key variables: iron, CO2, temperature, and vitamin B12.

Limitations
