The Impact of Phytoplankton Physiology on Global Climate
A new study explores the relationship between phytoplankton physiology and global climate. Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle. Variations in phytoplankton physiology, particularly nutrient uptake, can impact the chemical composition of the ocean and atmosphere, potentially affecting global climate. The study emphasizes the importance of variable stoichiometry of phytoplankton for regulating dissolved oceanic nutrient ratios and highlights marine oxygen levels as a critical regulator in the Earth system. Understanding these connections could help scientists make more accurate predictions about the future of ecosystems and climate.
