Which of these is an important phytoplankton nutrient that Martin studied?
Sulfur

Iron
Mercury
Answer
Iron, an essential phytoplankton nutrient, plays a crucial role in marine ecosystems. Martin's research revealed that iron fertilization of the oceans could significantly enhance phytoplankton growth and stimulate carbon dioxide uptake. This process, known as iron fertilization, has far-reaching implications for regulating atmospheric carbon dioxide levels and potentially mitigating climate change.
