Using the Earth as an Engine

​Join us for one of the most intriguing ideas in climate science: stimulating microscopic ocean life to help rebalance Earth’s atmosphere.

​The program will highlight the work of Exploring Ocean Iron Solutions (ExOIS) and trace the origins of the Iron Hypothesis, first proposed by renowned oceanographer John Martin. Martin famously suggested that adding trace amounts of iron to nutrient-rich regions of the ocean could trigger blooms of phytoplankton and diatoms. These are microscopic algae that absorb carbon dioxide and release oxygen through photosynthesis.

​Today, advances in ocean science, nanotechnology, and monitoring systems are reopening the discussion about whether carefully managed iron inputs could stimulate diatom blooms that enhance the ocean’s natural carbon cycle. Researchers are now examining how these processes might contribute to climate mitigation while supporting marine ecosystems.

​This event will bring together scientists, innovators, policymakers, and students to explore the science, opportunities, and challenges behind ocean-based carbon solutions.

​Join us for an engaging discussion on how the smallest organisms in the ocean may play a powerful role in addressing one of humanity’s biggest challenges.
